-1sentinel is sound. Note one interaction with the generated client.Your reasoning at lines 14-19 holds. A bare
doublecannot carry null in proto3 JSON, and zero CPU is a real reading, so-1correctly separates "idle" from "unknown".One consequence travels downstream. go-swagger renders these two fields as
float64withjson:"cpu_usage_percent,omitempty"inapi/om/v1/json/client/om_service/get_topology_responses.goat line 924 and line 927. On marshal,omitemptydrops a legitimate0.0. Decoding the server payload stays correct, because an absent field becomes0.0and the server always sends-1or a measured value. The gap appears only if code re-serializes the client model and a consumer separates absent from zero.No change is required here. Changing the type to
DoubleValuewould contradict the convention you documented. Simply be aware of the asymmetry if a consumer ever round-trips these models.🤖 Prompt for AI Agents

41-42: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick winConsider enums for the status sets PMM itself produces.
Three fields enumerate a closed set in a comment but carry type
string:
- Line 42:
Service.status— "UP" or "DOWN".- Line 177:
Run.status— running, success, partial or failed.- Line 429:
InventoryRunEntity.resolution— name, address or orphaned.PMM produces all three, so the sets are closed and under your control. A proto enum would make each set machine-checkable and would generate typed constants for both the Go client and the TypeScript UI, in place of string comparisons.
One point argues for acting now rather than later. The repository guideline forbids retyping an existing field, so
stringbecomes permanent oncev1ships.Keep
stringfor the fields you proxy verbatim.SourceReport.statusat line 152,InventorySetting.reloadat line 471, andInventoryService.probe_statusat line 320 all originate in SEP, and line 319 says so plainly — "in the payload's own words". An enum there would break when SEP adds a value. Your split is the correct instinct; only the PMM-owned fields merit reconsideration.The decision is yours, Captain.

estate with no rows” case so its name accurately describes the expected
SourcePartial status while retaining the existing assertions and behavior.
In `@managed/services/om/sources.go`:
- Around line 333-334: Update metricsSource.each to evaluate s.vm.Query using
the metricsSource run instant s.now instead of time.Now(), keeping observedAt
and query evaluation based on the same timestamp.
In `@managed/utils/envvars/parser.go`:
- Around line 126-128: Update the environment-variable parsing flow before the
existing logrus.Tracef call to filter PMM_SEP_TOKEN and PMM_SEP_URL, preventing
their original assignments from being logged; retain the existing skip behavior
in the parser’s switch so these keys are excluded from server settings.
In `@ui/packages/plugins/om/src/components/ConfigForm.tsx`:
- Around line 148-157: Update the TextField helperText in the ConfigForm
rendering logic to use kind-specific validation guidance: retain “A whole number
greater than zero.” for int settings and provide an appropriate non-empty text
instruction for text settings such as REPO_URL.
In `@ui/packages/plugins/om/src/constants.ts`:
- Line 119: Reformat the OM plugin sources with Oxfmt: update the
RUN_STATUS_COLOR declaration in ui/packages/plugins/om/src/constants.ts:119, the
wrapped ternaries and toHostRows signature in
ui/packages/plugins/om/src/inventory.ts:84-94, and the joinServiceInventory
assertion in ui/packages/plugins/om/tests/inventory.test.ts:266-270. No logic
changes are needed.
In `@ui/packages/plugins/om/src/inventoryHooks.ts`:
- Around line 186-200: The refresh transition handling must invalidate host and
service inventory queries in addition to runsKey so rows update immediately on
terminal status. Export a shared invalidation helper alongside runsKey and
servicesKey, then invoke it from the transition handler used by RefreshButton
and the scoped refresh controls in HostsPage.
In `@ui/packages/plugins/om/src/InventoryPage.tsx`:
- Around line 340-354: The LastRun component currently renders with rows[0]
before the refresh query has successfully resolved, causing a false empty-run
state during loading or failure without cached data. Update the LastRun
rendering in InventoryPage so it appears only when cached run data exists or the
request completed successfully with an empty response, while preserving the
existing loading and error displays.
In `@ui/packages/plugins/om/src/ServicesPage.tsx`:
- Around line 419-426: Update the isError branch in ServicesPage so the
first-run 503 state retains an available SyncButton recovery action, either by
rendering SyncButton alongside the error Alert or by preserving OmHeader with
its action; keep the existing error message display unchanged.
In `@ui/packages/plugins/om/src/useOmBase.ts`:
- Around line 20-43: Update ui/packages/plugins/om/src/useOmBase.ts lines 20-43
so CHILD_PATTERNS is derived from OM_ROUTE_SERVICES, OM_ROUTE_HOSTS, and
OM_ROUTE_INVENTORY in constants, matching the routes declared by OmApp. Update
ui/packages/plugins/om/tests/useOmBase.test.ts lines 34-44 to replace the stale
topology, runs, and clusters/:id cases with services, hosts, and inventory
cases.

Nitpick comments:
In `@api/om/v1/om.proto`:
- Around line 43-46: Make no changes to the proto fields or their sentinel
representation; retain the double types and -1 unknown-value convention for
cpu_usage_percent and connections_free_percent.
- Around line 41-42: Define protobuf enums and use them for the PMM-owned
closed-set fields Service.status, Run.status, and InventoryRunEntity.resolution,
with values covering their documented states. Leave the SEP-originated string
fields SourceReport.status, InventoryService.probe_status, and
InventorySetting.reload unchanged.
In `@managed/services/om/facts_test.go`:
- Around line 36-42: Replace the shadowed builtin new calls in
managed/services/om/facts_test.go at lines 36-42, 119-121, 126-127, 143, 146,
159, and 186-190 with the appropriate github.com/AlekSi/pointer helpers, using
pointer.To for the existing values. In managed/services/om/projection_test.go at
lines 294-295, replace new("127.0.0.1") with pointer.ToString("127.0.0.1") so
both statements use the same pointer convention.
In `@managed/services/om/inventory_client.go`:
- Around line 147-157: Remove the unused sendEmptyBody field and its explanatory
comment from inventoryCall, leaving the existing body handling and
TriggerInventoryRefresh behavior unchanged.
In `@managed/services/om/inventory_test.go`:
- Around line 98-125: Add a mutex to sepStub and lock it while the HTTP handler
records method, path, query, and body. Introduce a small accessor that acquires
the same mutex before returning the recorded request values, and update test
reads to use that accessor so newSEPStub is race-safe.
In `@managed/services/om/probe_source_test.go`:
- Around line 93-102: Replace context.Background() with t.Context() in every
collect call across the subtests in this test, including the locations
identified in the review, and remove the now-unused context import.
In `@managed/services/om/service.go`:
- Around line 232-245: Update Service.discover so a failed s.running.TryLock
does not wait indefinitely on s.running.Lock: either return the existing
snapshot immediately and codes.Unavailable when absent, or coordinate completion
through a channel that closes when the in-flight collection publishes and select
on ctx.Done(). Preserve the existing collection path for callers that acquire
the lock.
- Around line 156-179: Thread request contexts through the OM database call
chain: update ListTopologyRuns and GetTopologyRun to accept ctx and pass it to
listRuns and getRun; update readInventory, listRuns, getRun, persist, and
restore to accept context and use InTransactionContext(ctx, nil, ...) instead of
InTransaction. Apply changes at managed/services/om/service.go lines 156-179 and
355-396, and managed/services/om/store.go lines 136-165.
In `@managed/services/om/sources.go`:
- Around line 363-372: Replace the local slicesChunk helper with the standard
library slices.Chunk in the queryBatch batching flow, importing “slices” and
passing the existing positive queryBatch constant unchanged. Remove the
now-unused slicesChunk definition.
In `@ui/packages/plugins/om/src/components/ConfigForm.tsx`:
- Around line 219-225: Update the draft seeding in the editable useEffect and
the dirty-detection comparison in ConfigForm to convert nullish setting values
to an empty string instead of the literal “null” or “undefined”; keep non-null
values stringified as before so displayed drafts and change detection remain
consistent.
In `@ui/packages/plugins/om/src/hooks.ts`:
- Around line 348-354: Update useInvalidateOmTopologySnapshot to return a
useCallback-wrapped function with the appropriate dependencies, keeping the
existing topologyKey and runsKey invalidations unchanged while ensuring the
callback identity remains stable across renders.
- Around line 312-318: Update useOmTopologyRun to use a camelCase runId
parameter, add a limit parameter, and forward that limit to useOmTopologyRuns so
it shares the caller’s cache key and request. Preserve the existing run lookup
and returned rest fields.
In `@ui/packages/plugins/om/src/HostsPage.tsx`:
- Around line 193-198: Update the Repository column’s accessorFn to assign
unreachable repositories (repo present with latency_ms null) a finite sort key
that ranks after measured latencies but before Infinity, while retaining
Infinity for hosts without a repo record. Keep RepoCell rendering unchanged.
In `@ui/packages/plugins/om/src/inventoryHooks.ts`:
- Around line 247-257: Update useOmInventoryRun to wrap runId with
encodeURIComponent when constructing the inventory-run request path, and access
the status via optional chaining before calling isRefreshActive so missing run
data does not throw.
In `@ui/packages/plugins/om/src/OverviewPage.tsx`:
- Around line 212-213: Update the TableRow key in the cluster.services.map
rendering to use the unique service_id field instead of the display-only
service_name, preserving stable identity and avoiding duplicate keys for
services with the same name.
- Line 275: Update the getRowId callback to use a cluster-specific fallback
instead of UNNAMED_ENVIRONMENT; introduce and use an UNNAMED_CLUSTER constant,
or use an empty string fallback, while preserving row.cluster_name when present.
In `@ui/packages/plugins/om/src/types.ts`:
- Around line 27-28: Remove the stale orphaned documentation comment about
worker health verdicts and the `unknown` case, leaving the `OmServiceStatus`
documentation comment intact.
- Around line 489-496: Update OmInventoryRunAccepted.status from string to the
existing OmTopologyRunStatus union, matching the status typing used by the other
run interfaces and preserving compatibility with RUN_STATUS_LABEL and
RUN_STATUS_COLOR.
In `@ui/packages/plugins/om/tests/toClusterRows.test.ts`:
- Around line 49-70: Update the topology factory to derive summary.clusters,
services_total, services_up, and services_down from the supplied environments
instead of hardcoding zeros, while preserving the existing environment count and
by_process_role fields.
- Around line 166-197: The test case should also verify that null service states
are excluded from the state roll-up. In the test named “skips services that
report neither, and keeps null when nobody does,” add an assertion that
rows[0].by_state equals { PRIMARY: 1 }, preserving the existing lag, oplog, and
process-role assertions.

Ten of CodeRabbit's thirteen findings, plus both failing checks. Two of
the thirteen are declined with reasons; one is a false positive.
Security:
* PMM_SEP_TOKEN no longer reaches a log. ParseEnvVars traced the whole
original assignment before the switch that skips SEP's variables, so
a bearer token was written at trace level forty lines before the code
that meant to ignore it. PMM_SEP_URL is redacted with it, because a
URL can carry credentials in its userinfo and a rule that relies on
nobody writing one that way is not a rule.
* OM's gRPC writes are no longer viewer. methodRules is keyed
"METHOD /path" and a gRPC method name carries no verb, so
/om.v1.OmService/DeleteInventoryHost walked past every write rule and
landed on the "/om." prefix. The five write methods are now named
exactly in `rules`, beside the agent and RTA endpoints, and
TestResolveRule covers all five plus two reads.
Correctness:
* metricsSource evaluates its queries at s.now rather than time.Now().
observedAt subtracts the reported age from s.now, so the two instants
differed by however long the run had been going. With a 30-second
freshness floor a slow run could push a volatile fact over the line
and read a live service as DOWN.
* observedInt32 drops a value that will not fit rather than wrapping
it. Both callers are a port and a PID, where a wrapped result reads
as a plausible one.
* The estate is invalidated when a refresh *finishes*, not when it is
accepted. The mutation's onSettled fires tens of seconds early, so
hosts and services could sit stale for a full ESTATE_POLL_MS after a
refresh the user asked for and was watching. Both the Inventory
button and the per-row Hosts action use it.
* Services keeps its Sync action when the topology call fails. A 503 is
the expected first-run state and Sync is the way out, so the branch
that rendered only an alert named the fix without offering it.
* The Runs tab no longer claims "no refresh has run yet" while the
first request is in flight or has failed with nothing cached. That is
a statement about the estate, not a loading state.
* useOmBase strips the routes OmApp actually declares. CHILD_PATTERNS
still named topology, runs and clusters/:id from an earlier shape and
matched nothing that ships; it is derived from the route constants
now, so a rename cannot leave a pattern behind. Its tests asserted
the same stale segments, which is why they passed.
* ConfigForm's helper text matches the field kind. The int-only message
appeared on text settings, where the rule is only that the box is not
empty.
* The probe-source subtest name says partial, which is what it asserts.
CI:
* oxfmt. Four of the five files were already clean; the fifth,
apps/pmm/src/router.tsx, is outside the OM package and needed the
formatter run from the UI root, which is where CI runs it.
* api/om/v1/om.pb.go carries the blank line before depIdxs that its
fifty siblings carry, so `make gen` no longer leaves the tree dirty.
Worth knowing: `buf generate` in this workspace emits that line for
no generated file, while CI and every committed file have it, at the
same pinned protoc-gen-go. gofumpt preserves it either way. Until
that divergence is understood, regenerating .pb.go here and
committing it will reintroduce the failure.
Declined:
* Marking UpdateInventoryConfigRequest.values `required` would be
satisfied by `{}`, which is the empty batch the handler already
rejects with a message naming the problem. It would put a vaguer
rejection in front of a specific one.
* The generated swagger clients do not need a license header:
.licenserc.yaml ignores **/json/client/**, and none of the 102
generated client files in inventory/v1, server/v1, backup/v1 or
actions/v1 carries one.

Base branch: this should retarget to
So retargeting changes the diff by nothing - it only puts the PR under the branch it should have been opened against. Doing it now, while the two are identical, is free; once I have not changed it myself, since the base is the sort of thing worth agreeing on rather than switching under a review in progress. Happy to retarget if that reading is right. |

PMM stores cluster and replication_set as flat string columns and has no topology
object, so reconstructing replica sets and sharded clusters is a gap in PMM rather
than a feature belonging elsewhere. Both inputs are already here: the inventory in
PostgreSQL and the exporter metrics in VictoriaMetrics.
Sources emit flat facts keyed by (service, field) and merge by a declared per-field
precedence table, never by call order, keeping each field's provenance. That is what
lets SEP's discovery app contribute on-host facts - installed binary version, config
path, argv - without any source knowing about the others. Its facts are pulled over
HTTP; the source reports itself disabled when SEP is not configured, so a PMM without
it is a normal state rather than a failure.
Three properties of the data are load-bearing:
- VictoriaMetrics instant queries look back five minutes, so a stopped database
reported up for that long. Every selector now states its own window.
- last_over_time does not carry a sample's age, and timestamp(last_over_time(...))
reports the evaluation time rounded to the step, which reads as fresh for a series
last scraped days ago. MetricsQL's lag() is the only honest answer.
- One service can carry several series of one metric, so the merge breaks ties by
recency. Without that the document can call a live primary a secondary.
Facts are read over a long window and kept with their age; a per-field rule decides
what may be read as current. State and the gauges expire, a version does not, so a
stopped database reads DOWN while still reporting what it last was.
Runs and documents are persisted in schema 119, pruned on write, and restored on a
cold start. The document is JSONB rather than a relational tree because the topology
model is still moving; schema_version is what a reader checks.
/v1/pom is viewer-only: the trigger recomputes a document, it does not change the
estate.

ui/packages/plugins/pom is a bespoke plugin like ATW, composing its own routes over the topology document pmm-managed serves at /v1/pom. Three pages, each answering a different question. Overview is the estate the way the document is shaped: a table per environment, a row per cluster, each row unfolding into the services it was rolled up from. The roll-up is derived from the same snapshot the table renders, so the two cannot disagree. Lag takes a cluster's maximum and the oplog window its minimum - lag is a problem at its worst member, a window is a budget that runs out at its tightest - and a service reporting neither is skipped rather than counted as zero. Topology is the whole estate flat, with environment and cluster leading. Sorting and filtering are only useful across the whole estate, which a nested render cannot do. Five columns that are constant, internal, or long start hidden. Discovery shows SEP's pom_discovery sweeps and unfolds a run into a row per service: executor host, how it was matched, outcome, wall-clock, fact count. Two sentinel conventions, kept distinct because they answer different questions. The percentage columns treat -1 as "not measured" and every other value including 0 as a reading, so an idle server never renders as unmonitored. The duration columns treat null as "not applicable", which is what a router reports for an oplog it does not have. Both are handled once, in components/Metric. PomPage keeps the PMM-admin check and drops SepAuthGate: the nav only hides entries, the route still matches on direct navigation, and a page served by pmm-managed must not fail closed on a SEP session exchange. Only the Discovery route is mounted inside SepPage, so only it waits on the bearer. The transport is a same-origin fetch rather than PMM's axios client, which would camelCase the response out from under these hand-written types. Types stay snake_case, matching the wire shape verbatim. The pages refresh themselves. Every query stopped refetching once no run was observed in flight, so a page showed whatever it loaded with while both sides moved on underneath: pmm-managed rebuilds the document every 30s, and SEP's beat runs a sweep every ten minutes. The topology polls, the histories poll slowly when idle and fast while a run is active, and the trigger invalidates on settled rather than on success -- a 409 means a run is in flight and the document is about to change, which is when a refetch is most obviously wanted. A sweep's per-service records are written only when it ends, so its detail is empty until then. That answer was cached indefinitely, which left a finished sweep reporting no detail until the page was reloaded; the detail is now kept only while the sweep is terminal, and polled while it is not. The empty state distinguishes a sweep still running, one that failed before mapping anything, and one that genuinely recorded nothing -- previously all three read as data loss.

`GET /facts` served whatever the most recent completed sweep collected. That shape loses data on exactly the sweeps that matter: a service the newest sweep failed to reach contributed no facts at all, so this merge dropped every probe field for it - version, config path, argv - until some later sweep happened to succeed. A node that went unreachable therefore looked to PMM like a node with nothing installed on it, which is the one conclusion it must never draw. `GET /services` is the app's estate table, upserted rather than replaced. The same service still answers with what it last reported and when, so an unreachable host degrades into aged facts instead of absent ones - which is what the consumer was already built for, since every fact carries its own `observed_at` and merges by precedence. Three things follow from reading rows instead of a run: - **The verdict describes coverage, not a sweep.** `sweepFailed`/`sweepPartial` had no meaning once no single run owns the answer. This counts services covered against services failing: all failing is `SourceFailed` with `probe_all_failing`, some covered is `SourcePartial`, everything covered is `SourceOK`. An estate whose rows exist but have never been probed is `Partial` - not an error, because nothing failed, and not OK, because nothing is known. - **A failing service says why on the receipt.** The row carries `last_error`, `failing_since` and `consecutive_failures`, so the error names a service and its cause rather than sending the reader to another service's logs to find out. - **Each fact is dated from its own row.** `collected_at` was one timestamp for a whole sweep; now it is per service, and a document that is a month stale sits beside one from a minute ago without either being mislabelled. Services the app holds but this PMM does not are counted in `services_unknown` rather than merged. The two inventories are read independently and can be a moment apart in either direction; a fact with nothing to attach to is a normal transient, not a discrepancy worth an error. Signed-off-by: Pawel Lebioda <pawel.lebioda@percona.com>
The browser must not hold a SEP bearer. A page that talks to the discovery app
directly needs one minted from the PMM session, so it is gated on SEP being up,
configured, and willing to exchange the token - and it fails closed, which means a sick
SEP blanks the page instead of showing an estate with an error on it. Proxying costs a
second hop and buys "SEP is unreachable" as an error *inside* a page that still renders,
which is the difference between a diagnosable estate and a blank one.
Mounted at /v1/pom/inventory rather than under /v1/pom/discovery, because two different
things would otherwise be called a "run" one path segment apart. /v1/pom/discovery/runs
is PMM's own collection pass: inventory plus VictoriaMetrics, a tenth of a second, never
touches a host. /v1/pom/inventory/runs dispatches a Nomad job per host and takes tens of
seconds. Nothing but the path tells a caller which one they just started.
**`observed` is carried twice, on purpose.** The attributes a table sorts by are real
proto fields; the whole document rides alongside as a `Struct`. The app stores
observations as JSON precisely so that collecting a new attribute is a payload change
rather than a schema change, and enumerating every attribute here would put that
coupling straight back - while passing only the `Struct` would leave the TS side an
untyped bag with no compiler error when a key is renamed. Confirmed while building it:
`repo.*` was added to the payload by other work in flight, and it appears in the
response with no proto change, no `make gen`, and no code here knowing it exists.
Every nullable field is a wrapper rather than an `optional` scalar, because protojson
drops an unset `optional` entirely even under EmitUnpopulated. A silently absent
`failing_since` is a column that reads "not collected" when the truth is "never failed".
Verified against a sandbox host that has never been probed: the nulls arrive.
One bug found by building it. `POST /runs` marshalled the node-id list straight from the
request, and Go renders a nil slice as JSON `null` while the app types the field
`list[str]` - so every *full-estate* refresh through this proxy would have answered 422
while a scoped one worked. That is the shape of bug diagnosed as "the trigger is broken
sometimes". Materialised as an empty slice, with a test pinning the request body.
Two decisions worth disagreeing with:
- **The app owns validation, this does not.** A config change is forwarded as received
and rejected there; a second set of rules here would drift from the first. The only
thing refused locally is an empty batch, which would otherwise succeed and change
nothing.
- **A rejected credential is not reflected as-is.** The app's 401 becomes Internal
rather than passing through, because a 401 from PMM's gateway tells the browser to
re-authenticate against PMM, and PMM's credential for SEP is what actually failed. 404
and 409 do pass through, since "no such host" and "another refresh holds this host" are
answers a caller acts on differently from a failure.
`PATCH /config` binds the body directly (`body: "values"`), so the request this takes is
the object it forwards, rather than wrapping it as `{"values": {...}}` and making the
proxy's shape differ from the shape of the thing being proxied.
Verified through PMM's own gateway against the sandbox: hosts with their services and an
unregistered mongod beside one, the flat service list, the run history, config, a
full-estate refresh, a scoped one, a 404 for an unknown host, and a 409 naming the run
that holds it. A config change reached the beat schedule row with nothing restarted.
Also here: two lint findings in probe_source.go from the commit that introduced it, and
its startup log line still naming the retired /facts path.

REVIEW NOTE: this commit is on its own because it decides who may do what. **It needs sign-off from the PMM and SEP teams**, together with the related question in PMM-15326's plan §10 - the two are the whole authorization story for POM, and each assumes an answer to the other. The write-up is in the plan at §12. `rules["/v1/pom"] = viewer` carried a comment saying POM only reads, and that was true when the only write recomputed a document from data PMM already held. It stopped being true with /v1/pom/inventory, which can forget rows, change the discovery app's configuration, and run code on database hosts. Left alone, every one of those was a viewer's to do. What is implemented, and the reasoning a reviewer should push back on: - **Refreshing is editor.** It runs SEP's fixed probe payload on the hosts it covers: nothing the caller supplies, no database written. The per-host refresh is the button beside a row that answers "I just fixed this, is it healthy now", and putting that behind admin would gate the routine question on the rarest role. The conservative alternative is admin, on the grounds that it does execute a script on every database host it touches, fixed or not. - **Forgetting a row is admin.** Not suppression - the row returns on the next refresh if PMM still knows the entity - but destructive to that row's history. Arguably editor for exactly that reason. - **Changing configuration is admin.** It sets the sweep schedule for the whole deployment, which is something one person does on everyone's behalf. Method-qualified rather than path-qualified, using the `methodRules` map that already exists for alerting templates, so reads keep the viewer entry they have always had. The prefix walk is what makes any of this apply, and it is easy to get silently wrong: a rule spelled without its trailing slash is stepped straight past on the way down to "/v1/pom", and the surface would be viewer-writable with no error anywhere. So every path is asserted in TestResolveRule rather than assumed, including PMM's own collection pass staying viewer. Signed-off-by: Pawel Lebioda <pawel.lebioda@percona.com>
§12a.3 and §12a.4. Topology becomes Services and gains POM's estate beside PMM's snapshot; Hosts is new and is the page §4 exists for. **The join is a map lookup, and that is the whole payoff of keying the estate on PMM's own service id.** No matching function, no name-or-address heuristic, nothing to get wrong - unlike every other place in this system where two sources are lined up. Rows come from the snapshot, so a service PMM registered since the last sweep still appears with its probe columns saying why they are empty, rather than the row going missing. `version` and `installed_version` stay two columns and are never merged. One is what the running mongod reports over the wire, the other is what the package database on the host says; they disagree exactly when a package has been upgraded and the process not restarted, which is a state POM exists to find and one column could not express. **Hosts answers "which hosts have no database" in three states, not two.** PMM's own inventory cannot tell a bare pmm-client host from an arbiter - same node type, same agents, no services - so a two-state column would report an arbiter as an empty machine and invite someone to install over a port already in use. Confirmed live on this sandbox: `shard00arb0` and `shard01arb0` render as "Unregistered mongod" while `pmm-client-node00..02` render as "No database". The executor cell is one column rather than three booleans, for the same reason the API splits them: what a reader needs is what to go and do. "Not onboarded", "Agent down" and "Driver unhealthy" send them to three different places, and all three are visible on this sandbox right now. Two things worth knowing about the shape: - **`ProbeValue` renders a stale value with its age rather than a dash.** `Unavailable` says "there is no value and here is why"; the estate needs a third answer it cannot express - there *is* a value, it is old, and the last refresh failed. A dash would throw away the only information anyone has; showing it plainly would present three-day-old facts as current. Two new reason codes go with it, separating "POM has no row for this service yet" from "POM has a row and no probe has ever succeeded". - **The estate loading or failing does not gate either page.** The snapshot is PMM's own and always there; the estate is a second service that may be unwell. A page that blanked when it was would be exactly what proxying it through pmm-managed was meant to stop. The delete dialog says what deleting achieves rather than asking "delete this host?". It is not suppression - an entity PMM still knows about returns on the next sweep - and a reader who believes otherwise will use it as a mute exactly once. The mappers are plain functions with 20 vitest cases, following `toClusterRows`: the join and the three-state derivation are the parts with real logic, and they are testable without rendering anything. Verified against the sandbox through PMM's gateway, replaying what each cell renders: 20 hosts across all three database states and all three executor states, and the Services join at 14 of 14 once SEP's inventory copy was resynced. Before that resync it was 4 of 14, which is worth recording - the estate enumerates from SEP's inventory, so a stale copy there shows up here as services that look absent from POM. `cd ui && make lint && make test` both green: 8/8 lint tasks, 7/7 test tasks, 1279 tests. `AlertStatusTable` failed once under parallel load and passes on re-run and in isolation; it is a datetime-picker flake, not this change.

Two additions the Discovery page needs and the proxy did not have. **Host counters**, mirroring SEP `bc2a5e0` above. A refresh attempts hosts as well as the services on them, so a receipt counting only services makes a host-only refresh read as "0 of 0" - indistinguishable from a run that did nothing. **`InventoryRunEntity` on the detail response**, so a partial refresh can say *which* entities it missed. "5 of 14 answered" cannot say which five, on which host, or which host took a minute, and each of those is the first question asked of a slow refresh. Outcomes only, and deliberately so: which entity, on which executor host, matched how, answered or not, how long it took, and the error. What the probe *found* stays on the estate, where it is upserted and stays current. A receipt that also carried the attributes would be a second copy of the estate that goes stale the moment the next refresh runs, which is the duplication splitting the two apart was meant to remove. On the detail response only, never on the list: a real estate has a row per service, and a twenty-five-run history would carry the lot to render a page showing one at a time. Every nullable field is a wrapper. An orphaned entity has no service id, no executor host and no duration, and protojson drops an unset `optional` scalar entirely - so all three would silently arrive as empty strings and a zero. `buf generate --path pom/v1/pom.proto` rather than `make gen`: the full run rewrites 56 API files with a blank-line difference from a protoc-gen-go version that is not whatever produced the committed output. Scoping it keeps the diff to the package that actually changed. Worth knowing before anyone runs `make gen` here and wonders what they touched.

§12a.5, and the step that pays off the proxy. `RunsPage` becomes `DiscoveryPage` reading `/v1/pom/inventory`; `probeHooks.ts`, `RunNodes.tsx` and the `@sep/api` dependency are deleted, the `SepPage`-wrapped `/pom/runs` route is gone, and all four pages mount inside `PomApp`. **No POM path in the browser talks to SEP any more.** That was the point. `SepAuthGate` fails closed, so a SEP that was down, unconfigured or refusing the token exchange blanked this page entirely; now "SEP is unreachable" is an error *inside* a page that still renders, with the schedule below it still readable. It also means §10's open question about whether the service principal is an admin stays a server-side question and never reaches a browser. What the page gained: - **A last-run summary.** The table answers "has this been working"; the summary answers "what does POM know right now", which is the more common question and previously needed reading the first row and knowing it was the newest. A run still `running` shows its age, because that is what distinguishes working from wedged. - **Host counters beside the service ones**, from the commit below. Live on this sandbox the difference is stark: 20 hosts in scope, 3 probeable, 2 answered against 14 services with 1 resolved. The service counters alone said almost nothing about what that sweep did. - **Scope on the row.** Without it a single-host refresh reads as a full sweep that found one host, which looks like a catastrophic failure rather than what was asked for. Full sweeps render "all" in muted text rather than a count, because that is the ordinary case and nineteen rows saying so would be noise. - **A schedule form**, with the three rules that stop it lying: only runtime-changeable fields get an input, the effective value is re-read and rendered rather than the submitted one echoed, and the unit and the cost are stated beside the number. `facts_collected` is gone with the column that fed it, and `RunEntities` shows outcomes rather than observations - which entity, on which host, matched how, answered or not, how long, and the error. What the probe *found* is on Services and Hosts, where it is upserted and stays current; a receipt carrying it too would be a second copy that goes stale on the next refresh. The lockfile change is the `@sep/api` removal and nothing else. A plain `pnpm install` here also bumps two transitive versions and drops an `integrity` hash from `react-data-grid`, which is environment churn rather than intent, so the four lines that should change were applied by hand. `cd ui && make lint && make test`: 8/8 lint tasks with 0 errors, 7/7 test tasks, 1279 tests. Verified through the gateway after rebuilding pmm-managed: the counters populate on a fresh sweep and the detail endpoint returns 14 entities with their resolution, answered flag and host time.

The form had one input, for the sweep interval, and listed the other twelve settings read-only under a heading claiming they "need a restart". Eleven of thirteen are `hot` - they take effect immediately - so that heading was simply wrong about them, and they were read-only because the form stopped at the schedule rather than for any reason worth stating. `reload === 'hot'` is now the filter, and it drops exactly the two that genuinely cannot be edited rather than showing them greyed out to raise the question: - `CREDENTIALS_PATH`, deliberately not overridable. It names a file the payload reads on every database *host* and hands to a driver as a URI, so an editable one turns "configure this app" into "read a chosen file across the estate". - `FASTAPI_ENV`, which belongs to the framework rather than to POM. The input is chosen from the type the app declares, not guessed from the value. That matters for `STALE_RUN_AFTER`: it is a `timedelta` arriving as whole seconds, so a value-based guess renders it as a bare integer and "1800" beside "wedged after" is ambiguous in a way that costs someone an outage. Units are in the labels, and `SCHEDULE__period` is a select over the four periods rather than free text. Grouped by the app's own `is_advanced` flag rather than a list kept in the UI, so a setting SEP adds later lands in the right section without this file knowing about it. The eight advanced ones - timeouts, concurrency, retention - are collapsed, because `MAX_CONCURRENT_PROBES` sitting beside the schedule invites fiddling with something that costs Nomad capacity. **Where a value came from is said once, not per field.** Marking every unoverridden field "from the deployment's configuration" is the same sentence thirteen times: it tells a reader nothing and buries the two or three rows that *are* overridden, which are the only ones where the origin is worth knowing. It sits on the section's own line, and the per-field space carries only the exception - an "overridden" chip and its Reset. The Hosts page already applies that rule to the repository column, which speaks up only when a host cannot reach one. Saved as one batch, which is what the app actually does: a single bad key rejects all of it and writes nothing. Per-field saves would have misrepresented that. Zero is refused client-side for every integer, because each of them breaks at zero - a zero semaphore admits nobody, a zero interval is not a schedule, a zero retention keeps nothing - and saying so beside the field beats a banner after a round trip. Verified against the sandbox through the gateway: all four value shapes round-trip (`bool`, the `Period` enum, `timedelta` as seconds, plain `int`), a batch carrying one bad key leaves the *valid* key in it unwritten, and every override reverts. `cd ui && make lint && make test`: 8/8 lint tasks with 0 errors, 7/7 test tasks, 1279 tests. `ui#test` failed once under parallel load and passed on re-run and in isolation - the `AlertStatusTable` datetime-picker flake, now recorded in `docs/pom-open-questions.md` rather than left to surprise the next person.

The two halves answer different questions on different clocks. "Did the last refresh work" is asked often and skimmed; "how often should it run" is asked rarely and read carefully. Stacked in one column the second sat below a twenty-five-row table and was found by scrolling. The tab is in the query string rather than component state, so `?tab=settings` is a shareable link and a reload leaves the reader where they were instead of quietly returning them to Runs. An unknown value falls back to Runs rather than rendering nothing. Refresh stays in the page header rather than moving inside the Runs tab: it is the page's action, and hiding it while someone reads the schedule would mean going back a tab to act on what they had just changed. `ConfigForm` loses its own "Configuration" heading, which under a tab labelled Settings was the same word twice.

Follows SEP a88d2e14. A sweep refused because another already held its hosts records `skipped` rather than returning silently, so the run history has a status the frontend did not know. The chip is neutral, not red. Skipped is neither a failure nor a success - the sweep did nothing, deliberately - and colouring it as a failure would put a red row in the history every time the ten-minute schedule met a manual refresh.

Unfolding a refresh on the Discovery page showed a table of services, so a machine carrying a PMM client and no database appeared nowhere in it - however many times the refresh had probed it. The counters said three hosts answered; the receipt could name one. That host is the case POM most exists to describe: it is where a database can be installed, and it has no service to be listed through. A sweep attempts **hosts**. It has since a host became probeable for its own sake, and the receipt was the last part still shaped as though services were the unit of work. `nodes` is now one entry per host - node id, name, executor host, how it was matched, whether the host answered, how long it took, its error - with the services on it nested underneath, carrying only what is theirs. Two things fall out of that shape rather than being decided separately: - **A host's duration is reported once.** It used to be copied onto every service the host served, which read as several measurements of several things when it was one measurement of one dispatch. - **"Answered" stops being ambiguous.** Whether the *host* answered and whether its *services* did are different questions, and a host with no database answers perfectly well while having no services at all. Flattened together there was no way to say that. `services: []` is a meaningful answer and renders as "none" rather than as an empty cell, for the same reason `pom.host` keeps rows for hosts with no service. Still outcomes and never observations: what the probe *found* belongs to the estate, which is upserted and stays current. A receipt carrying the attributes as well would be a second copy going stale on the next refresh. The sweep tests move with it, and one of them changes meaning: it used to assert the duration was repeated across a host's services, which is precisely the behaviour being removed. It now asserts the opposite, and a new test covers the case that could not be expressed before - a probed host with no database appearing in the receipt at all. Regenerated with `buf generate --path pom/v1/pom.proto` rather than `make gen`, which rewrites 56 unrelated API files from a different protoc-gen-go.

Two user-visible strings: the sidebar's top-level entry and the Overview page's heading. The comment in `PomHeader` describing that nav entry follows them, so it does not name something the reader cannot find. The remaining "PSMDB Open Manager" occurrences are deliberately left. They gloss where the acronym POM comes from - in `router.tsx`, `lib/constants.ts` and the workspace docs - and that origin does not change because the displayed name got shorter. Renaming them would leave "POM" unexplained. No test pinned the old string, and none needed updating. Signed-off-by: Pawel Lebioda <pawel.lebioda@percona.com>
pom/v1 was missing from api/Makefile's SPECS list, so `make gen` emitted pom/v1/pom.swagger.json only as an intermediate and then deleted it in clean-swagger. POM had no per-API spec, no generated Go client, and no presence in swagger.json or swagger-dev.json: the /v1/pom endpoints existed but were invisible to the Swagger UI, to the published API spec, and to anything consuming the generated clients. Add pom/v1 to the SPECS list in both gen and clean, and to both aggregated spec mixins, with a json/header.json titled "PMM OpenManager API". It goes in the public spec because it is v1 - that spec omits only agentlocal and the protos that are still in beta. Signed-off-by: Pawel Lebioda <pawel.lebioda@percona.com>
The product is OpenManager, not PSMDB OpenManager, so `pom` becomes `om`: the API package is `om.v1` serving `OmService` under `/v1/om`, pmm-managed's service is `managed/services/om`, and the UI plugin is `@sep/plugins-om` mounted at `/pmm-ui/om`. The interesting half is what "discovery" meant, because it meant two things. `/v1/pom/discovery/runs` was pmm-managed deriving the topology document from PMM's own inventory and VictoriaMetrics, while `/v1/pom/inventory/*` proxies SEP's app, whose runs probe hosts. Both were "runs" and only one is the estate, which is exactly the confusion that made a reader check the code to tell which endpoint they wanted. So the word is retired. What pmm-managed derives is **topology**: GET /v1/om/topology the document GET /v1/om/topology/runs ListTopologyRuns GET /v1/om/topology/runs/{id} GetTopologyRun POST /v1/om/topology/runs TriggerTopologyCollection with `om_topology_runs` / `om_topology_snapshots` behind them, and `OmTopologyRun` / `OmTopologySnapshot` / `OmTopologySourceReport` in the models. What SEP's app holds stays **inventory**, and the UI page that reads `/inventory/runs` is now Inventory at `/pmm-ui/om/inventory`, which is what its nav entry always should have said. Nothing in the two subsystems' behaviour changes; only the names stop overlapping. Migration 119 is edited in place rather than followed by a rename migration. It has not shipped - the branch is unmerged - and a rename migration would keep the old table names in the tree permanently for databases that exist only on our own laptops. An existing `/srv` therefore still has `pom_runs` and will not migrate across; reset it (`./om reset data`) and let the bootstrap rebuild. Everything under `api/om/v1/json/`, the `.pb.go` files and both aggregated swagger specs come from `make gen` followed by `make format`, not from a text substitution. `om.pb.go` embeds the file descriptor as length-prefixed strings, so rewriting `pom.v1` to `om.v1` in place would have left every prefix one byte too long and corrupted the descriptor. Two things are deleted rather than renamed. The `/pmm-ui/sep/pom` redirect went: it existed for links from when POM's backend was a SEP app, and nothing that URL points at is being kept. And the comments citing SEP's `pom_worker` and `pom_api` went with it - those apps were deleted and their commits will be squashed, so a renamed citation would name something no history contains. Verified: `go build ./...`, golangci-lint clean on every renamed package, `managed/services/om` tests, 54 plugin tests, 385 UI app tests, and `tsc --noEmit` for both the plugin and the app. The DB-backed `managed/models` tests and the Grafana auth tests need a live PostgreSQL and Grafana and were not run.

Reviewed api/om/v1/om.proto against the PMM API Guidelines and fixed
everything the guidelines ask for. Twelve findings; eleven are changed
here and one is a deliberate keep, recorded below.
None of this was caught by CI: `buf lint` was clean before and after.
The one actual defect, which is not a style matter:
* The `executor` filter on ListInventoryHosts was a StringValue
documented as "only hosts served by this Nomad client", while the
app types it `bool | None` and filters on whether an executor is
matched at all. Every hostname was a 422 from the app, surfaced as
a 400 from PMM, so the documented filter could not be used. It is
a BoolValue now. The test asserted the broken shape against a stub
that never validated, which is why nothing failed.
Methods and paths, so the standard methods are actually standard:
* `PATCH` -> `PUT` on /v1/om/inventory/config. The guidelines require
an Update to be PUT, and this was the only `patch:` in all 53
protos against eight `put:`. SEP keeps PATCH: its overrides are
applied by a generic settings router that patches every class, so
the verb there is not this app's to pick, and translating one
method is what a proxy is for.
* UpdateInventoryConfig answers with the whole configuration rather
than the submitted keys. The app returns one row per key named in
the request, which is misleading for a nested write: overriding a
parent moves what its children resolve to and no row says so. The
handler reads back after the write. A failed read-back does not
fail the call, because the write already landed and an error would
invite a retry of a change that applied.
* The two triggers carry the colon verb the guidelines require for a
custom method: POST /v1/om/topology/runs:collect and
POST /v1/om/inventory/runs:trigger. It matters most on the second,
which returns an accepted run that finishes tens of seconds later,
where POST /runs answering 200 reads as "done".
* Reverting one setting moved from /config/{key} to
/config/overrides/{key}. `config` is a singleton resource - Get
returns it, Update replaces part of it - so using it as a
collection in one method made it both at once. `overrides` also
names what is removed: the setting always exists, the override on
it is the thing with a lifecycle.
Types, where a string was standing in for a closed set:
* Six enums - ServiceStatus, ProcessRole, RunStatus, SourceStatus,
ExecutorResolution, SettingReload - replacing strings whose
permitted values lived only in a comment. Every status-like field
elsewhere in PMM is already an enum, and none of these carried a
validation rule, so nothing caught a typo.
Two real gaps fell out of having to enumerate the values.
RunStatus was missing SKIPPED, which SEP has and the plugin's own
union already carried, so a refresh declined by the single-flight
guard would have arrived unrecognised. SettingReload nearly lost
NESTED_ONLY, where a parent refuses a whole-object write while its
children accept one - collapsing it would have made a form refuse
to edit a leaf the API accepts.
The wire is more verbose for it: "success" is now
"RUN_STATUS_SUCCESS", because protojson serialises enums by name
and buf requires the type prefix on every value. Persistence stays
on the lowercase strings, translated in store.go, so a run row
stays readable in psql and renumbering cannot reinterpret history.
The SEP boundary has its own mappers in inventory.go, all falling
through to UNSPECIFIED, so a value the app grows later reaches a
caller as unknown rather than as a plausible wrong answer.
* node_ids is bounded and rejects empty entries. `values` is a
Struct and cannot carry field rules, so its one precondition stays
in the handler and now says so.
Names:
* started_at/finished_at -> start_time/end_time, the two spellings
the standard-fields table names outright.
* Counts read prepositively - total_services, orphaned_services,
probeable_hosts, successful_probes - rather than as postpositive
adjectives, which the guidelines call out and which made an int32
read like a repeated field three characters from the real one.
* by_process_role -> process_role_counts. A field name should not
lead with a preposition.
* Service/Run/RunCounts/RunError -> Topology*. The RPCs were renamed
to say Topology and the messages were not, leaving unprefixed
names beside InventoryService and InventoryRun with nothing but
convention to say which was which. `Service` is also the word the
guidelines single out as historically problematic, and it meant
three things across omv1 and models.
Not changed, deliberately: Get responses wrap the resource rather than
being the resource, which the guidelines ask for. All of PMM wraps,
buf's RPC_RESPONSE_STANDARD_NAME effectively requires it, and fifteen
Get responses elsewhere carry more than one field. GetInventoryRun
returning `run` alongside `entities` is the same shape as GetLogs
returning `logs` alongside `end`; putting entities on InventoryRun
instead would make an empty list on the list response ambiguous
between "not requested" and "attempted nothing".
Verified with buf lint, buf breaking, go build ./..., go vet, the om
and offline grafana test packages, tsc, the plugin's 54 tests, oxlint
and oxfmt. Regenerated the spec, the Go client and both aggregate
swagger documents; om/v1 is not in descriptor.bin, so buf breaking
passes and the enum change is still free until `make descriptors`.

Ten of CodeRabbit's thirteen findings, plus both failing checks. Two of
the thirteen are declined with reasons; one is a false positive.
Security:
* PMM_SEP_TOKEN no longer reaches a log. ParseEnvVars traced the whole
original assignment before the switch that skips SEP's variables, so
a bearer token was written at trace level forty lines before the code
that meant to ignore it. PMM_SEP_URL is redacted with it, because a
URL can carry credentials in its userinfo and a rule that relies on
nobody writing one that way is not a rule.
* OM's gRPC writes are no longer viewer. methodRules is keyed
"METHOD /path" and a gRPC method name carries no verb, so
/om.v1.OmService/DeleteInventoryHost walked past every write rule and
landed on the "/om." prefix. The five write methods are now named
exactly in `rules`, beside the agent and RTA endpoints, and
TestResolveRule covers all five plus two reads.
Correctness:
* metricsSource evaluates its queries at s.now rather than time.Now().
observedAt subtracts the reported age from s.now, so the two instants
differed by however long the run had been going. With a 30-second
freshness floor a slow run could push a volatile fact over the line
and read a live service as DOWN.
* observedInt32 drops a value that will not fit rather than wrapping
it. Both callers are a port and a PID, where a wrapped result reads
as a plausible one.
* The estate is invalidated when a refresh *finishes*, not when it is
accepted. The mutation's onSettled fires tens of seconds early, so
hosts and services could sit stale for a full ESTATE_POLL_MS after a
refresh the user asked for and was watching. Both the Inventory
button and the per-row Hosts action use it.
* Services keeps its Sync action when the topology call fails. A 503 is
the expected first-run state and Sync is the way out, so the branch
that rendered only an alert named the fix without offering it.
* The Runs tab no longer claims "no refresh has run yet" while the
first request is in flight or has failed with nothing cached. That is
a statement about the estate, not a loading state.
* useOmBase strips the routes OmApp actually declares. CHILD_PATTERNS
still named topology, runs and clusters/:id from an earlier shape and
matched nothing that ships; it is derived from the route constants
now, so a rename cannot leave a pattern behind. Its tests asserted
the same stale segments, which is why they passed.
* ConfigForm's helper text matches the field kind. The int-only message
appeared on text settings, where the rule is only that the box is not
empty.
* The probe-source subtest name says partial, which is what it asserts.
CI:
* oxfmt. Four of the five files were already clean; the fifth,
apps/pmm/src/router.tsx, is outside the OM package and needed the
formatter run from the UI root, which is where CI runs it.
* api/om/v1/om.pb.go carries the blank line before depIdxs that its
fifty siblings carry, so `make gen` no longer leaves the tree dirty.
Worth knowing: `buf generate` in this workspace emits that line for
no generated file, while CI and every committed file have it, at the
same pinned protoc-gen-go. gofumpt preserves it either way. Until
that divergence is understood, regenerating .pb.go here and
committing it will reintroduce the failure.
Declined:
* Marking UpdateInventoryConfigRequest.values `required` would be
satisfied by `{}`, which is the empty batch the handler already
rejects with a message naming the problem. It would put a vaguer
rejection in front of a specific one.
* The generated swagger clients do not need a license header:
.licenserc.yaml ignores **/json/client/**, and none of the 102
generated client files in inventory/v1, server/v1, backup/v1 or

The Checks job runs golangci-lint through reviewdog with --filter-mode=added, so three findings landed on lines the previous commit touched: - godot wanted the buildSummary comment to open with a capital, so it now leads with "The process_role_counts map" rather than the bare field name. - noinlineerr on the config read-back. err is already in scope from inventoryProbe, so this is a plain assignment rather than a third //nolint in the same function. - thelper on newSEPStub, which delegates to newSEPStubSeq and so never marked itself. No behaviour change. The make gen blank-line workaround from the previous commit held: "Check files are formatted and no source code changes" passed, and CI (oxfmt) is green.

CodeRabbit's follow-up on the values field: it accepted that
(validate.rules).message.required buys nothing on a Struct, since {}
satisfies it and the handler already rejects that case by name, but
asked for the structural bound underneath. That part is right.
Nothing bounds this on either hop. Measured against this tree,
protojson accepts 200k fields in a 2.3MB body - inside the 4MB default
gRPC message size - and nests to just under 10k before it refuses. The
app on the far side is Python, where the default recursion limit is
1000, so PMM would be the thing that broke SEP.
The settings class this proxies has ten fields and nests one level
(SCHEDULE and its children), so 100 fields and 10 levels cannot reach a
real caller. A test asserts the deepest legitimate shape - a
whole-object SCHEDULE write - still passes through.
This bounds shape, not meaning: which keys exist and what values are
legal stay the app's business, so there is still one set of validation
rules.

The generated client was pmm_open_manager_api_client.go while everything else in the API spells om. The lever is the swagger title, since go-swagger derives both the filename and the client type from it. Registering om as an initialism is what makes OM a word rather than two letters: without it the title yields pmm_o_m_api_client.go. That list is where PMM already keeps qan, ha, psmdb and pxc for exactly this reason. Signed-off-by: Pawel Lebioda <pawel.lebioda@percona.com>

Following up on the redaction fix discussed on #5811: the secret-redaction code for PMM_SEP_URL/PMM_SEP_TOKEN that landed here (across a few commits) turned out to duplicate that PR's fix. Both are now rebased onto the same updated PMM-15299-open-manager, which carries the consolidated version (reusing redactSecretEnvVar, ported from main's ba67206), so this branch's own copies were dropped rather than kept as a second implementation. |
