PMM-15326: Add the OM UI plugin

[plebioda]

Ticket number: PMM-15326

Feature build: N/A on its own - this package is not mounted anywhere until the navigation PR stacked on top of it lands. A build covering both is more useful than one per PR; happy to produce one.

What

@sep/plugins-om, the OpenManager plugin: four pages over pmm-managed's /v1/om, plus the shared components, hooks and types behind them.

• Overview - the topology document rolled up by environment and cluster.
• Services - one row per monitored MongoDB service, joined against the inventory estate.
• Hosts - the page a host with no database appears on, which no other OM page can show: it has no service to be listed through.
• Inventory - the collection run history and the app's runtime settings.

Two things worth knowing before reading

The plugin depends on @sep/api nowhere. Every page reads PMM's own origin, so no request it makes needs a SEP bearer - pmm-managed proxies SEP's estate at /v1/om/inventory and the Grafana session authorises the call. That is the whole reason this is a PMM plugin rather than a SEP one.

The types are hand-written, not generated. OM is not in PMM's checked-in OpenAPI client set, and types.ts says so at the top. The fields are typed ?: T | null because the wire form is a proto3 optional scalar: protojson omits an unset one rather than emitting null, so a missing key is what arrives, and every reader here uses == null, which catches both.

Two conventions the tables depend on, and they differ on purpose

cpu_usage_percent and connections_free_percent are -1 when not measured, never absent and never 0 - zero CPU is a real reading, so the numeric sentinel is what keeps "idle" and "unknown" apart in a numeric column.

replication_lag_seconds and oplog_window_seconds are absent when they do not apply - a router and a standalone have no replica-set oplog. That is a different statement from -1's "we could not measure it".

Both are documented in types.ts and mirrored in om.proto. If you would rather one convention covered both cases, that is worth saying now rather than after the columns ship.

The lockfile is split on purpose

ui/pnpm-lock.yaml here carries only this package's own importer block. The three lines adding '@sep/plugins-om' to the apps/pmm importer land in the navigation PR, with the package.json that declares the dependency - otherwise pnpm install --frozen-lockfile fails on both branches: this one would declare a dependent that does not declare the dep, and that one would be missing its own entry. Both branches were checked against --frozen-lockfile after the split, and again after the review round below.

What that block declares changed in review. It now carries date-fns and @vitejs/plugin-react, and no longer carries @vitejs/plugin-react-swc. date-fns is the monorepo's date library and already a dependency of apps/pmm; @vitejs/plugin-react is what main moved to. Both changes are scoped to this package - the rest of the tree is still on -swc because this branch's base predates that change on main.

Reviewing this

~6.3k lines, of which ~900 are tests and 580 are types.ts. The parts carrying the most judgement: topologyHooks.ts and inventoryHooks.ts (what is fetched, and when), topology.ts and inventory.ts (the roll-ups, the joins and the freshness helpers), then the four pages. api.ts is the transport both halves share.

Review round 1 (2026-08-25)

Fourteen inline comments from @fabio-silva across thirteen threads, and nine from Copilot. Twelve of thirteen taken, and all nine, across six commits (4c395dc → 504d7a7); each is answered in its own thread.

commit	what
8a38150	Services no longer reads a pending estate as an empty one; Overview keeps Sync in its error state; both refresh buttons derive "running" from every run rather than runs[0]; the Hosts table is keyed on node_id
c700ad7	pom.v1 → om.v1; the inventory types are exported; the dead useOmTopologyRun is deleted; aria-label on the config switches
4149c92	isRefreshActive folded into isRunActive; query keys uppercased; both triggers drop bodies they do not need; the timedelta wire contract documented
428084b	@vitejs/plugin-react; format.ts onto date-fns
e1d2c3c	hooks.ts split into api.ts / topology.ts / topologyHooks.ts; refreshAll() / refreshHosts() replace mutate(undefined); components converted to arrow functions
fc5e93a	the estate queries follow their own refreshes, so Services no longer shows pre-refresh rows for a minute

One thing held back, and it is the open question on this PR: the suggestion to change != null to !== null throughout. Proto3 optional fields are dropped by protojson rather than nulled - they sit in a synthetic oneof, which unpopulatedFieldRanger skips - so under !== the cluster roll-up admits undefined into Math.max and reports NaN for max replication lag and min oplog window on every row. Reasoning and references are in the thread on ProbeValue.tsx.

Two changes worth a second look, both deliberate but both visible:

• formatTimestamp moved from toLocaleString() to a fixed yyyy-MM-dd HH:mm:ss in local time. Run timestamps are compared down a column, so a stable format beats a familiar one - but it is a rendering change and easy to revert.
• The compact duration formatter was kept rather than replaced, and renamed formatCompactDuration. date-fns emits 2 days 3 hours where these cells need 2d 3h; the rename also ends a collision with date-fns' own export.

Related work

Sixth of seven stacked PRs splitting #5795 ("OpenManager initial implementation") into area-owned reviews.

• PMM-15326: Stop logging the SEP URL and token values #5811 - PMM_SEP_URL / PMM_SEP_TOKEN redaction
• PMM-15326: Add the OM topology tables and models #5812 - the OM topology tables and models
• PMM-15326: Add the OM API #5813 - the OM API this reads
• PMM-15326: Authorize the OM routes by role #5815 - the role rules for these routes
• PMM-15326: Implement the OM service in pmm-managed #5816 - the service that serves them

This PR targets PMM-15299-open-manager directly and depends on nothing else in the stack at compile time - the plugin's own vitest suite runs without the app declaring the dependency, because pnpm picks packages up by workspace glob rather than by dependent.

One thing the reviewer should know: PMM-15299-open-manager currently conflicts with main, and ui/pnpm-lock.yaml is one of the seven conflicting files - because the same pnpm toolchain migration (PMM-15288) landed on main as #5728 and on this branch via its own line. That conflict is not this PR's and does not affect merging into the base, but reconciling it later will touch this file.

Two different table libraries sail in the same plugin, mate.

This page uses material-react-table directly. InventoryPage.tsx (line 32) uses Table from @percona/percona-ui. Prefer the shared wrapper so that sorting, density, and theming stay consistent across OM pages. If the shared Table cannot express expanding rows plus row actions, record that limitation in a comment here.

As per coding guidelines: "Use MUI and @percona/peak-ui components for consistent styling — browse the Storybook catalog before building a component from scratch".

One refresh locks every oar.

refresh.isPending is a single mutation state, so a per-row refresh disables the Refresh button on every row and the "Refresh all" button too. Consider tracking the pending node IDs, or use useMutationState scoping, so only the acted-upon row is disabled.

- Around line 38-42: Update RESOLUTION_LABEL to use the prefixed
OmExecutorResolution enum values as keys, including every declared value and
EXECUTOR_RESOLUTION_UNSPECIFIED, while preserving the existing human-readable
labels.

In `@ui/packages/plugins/om/src/components/SnapshotBar.tsx`:
- Line 19: Update the Chip import in SnapshotBar.tsx to use Chip from
`@mui/material` instead of `@percona/percona-ui`, leaving its existing usage

In `@ui/packages/plugins/om/src/hooks.ts`:
- Line 55: Replace the hard-coded OM_BASE value with the applicable shared PMM
URL constant imported from src/lib/constants.ts, preserving the existing OM_BASE

ui/packages/plugins/om/src/OverviewPage.tsx at lines 275-275 and 432-432:
replace UNNAMED_ENVIRONMENT with stable identifiers derived from each topology
entry so unnamed clusters produce unique getRowId values and unnamed sibling
sections produce unique key values.

In `@ui/packages/plugins/om/src/ServicesPage.tsx`:
- Around line 374-395: Update the useOmInventoryServices integration and
joinServiceInventory flow to distinguish an inventory query failure from a
successful empty inventory: keep topology rows visible, mark inventory values as
unavailable rather than not_in_inventory, and expose a non-blocking inventory
error in the page. Ensure failingCount and failingOnly do not treat unavailable
inventory as healthy or as a successful empty result.

In `@ui/packages/plugins/om/src/types.ts`:
- Around line 96-630: Convert the exported OM models, including OmService,
OmServiceRow, OmServiceInventoryRow, and the related topology, run, probe,
inventory, host, and settings interfaces, to camelCase property names. Introduce
wire-only *Wire types retaining snake_case for axios responses, then map each
API response once in the data hook so UI state and exported TypeScript models
use camelCase consistently.

• This effect resets every draft whenever React Query supplies a new settings array. Since this query is immediately stale and refetches on window focus by default, switching away while editing can silently discard all unsaved changes when the user returns. Reconcile only untouched fields (or otherwise guard dirty drafts), while still reseeding after successful save/reset.

Thanks @fabio-silva - review round pushed, 4c395dc → fc5e93a. Replied in each thread; the summary:

Taken (13 of 15)

commit	what
8a38150	Services no longer reads a pending estate as an empty one; Overview keeps Sync in its error state; both refresh buttons derive "running" from every run rather than runs[0]; Hosts table keyed on node_id
c700ad7	pom.v1 → om.v1; the inventory types are exported; dead useOmTopologyRun deleted; aria-label on the config switches
4149c92	isRefreshActive deleted in favour of isRunActive; query keys uppercased; both triggers drop their unnecessary bodies; the timedelta chain documented
428084b	@vitejs/plugin-react; format.ts onto date-fns
e1d2c3c	hooks.ts split into api.ts / topology.ts / topologyHooks.ts; refreshAll() / refreshHosts() replace mutate(undefined); 30 components converted to arrow functions
fc5e93a	the estate queries follow their own refreshes, so Services no longer goes stale for a minute

Held back (1) - the != null → !== null change, and specifically the ask to apply it to the remaining operators. Proto3 optional fields are dropped by protojson rather than nulled, so under !== the cluster roll-up admits undefined into Math.max and reports NaN for max replication lag and min oplog window on every row. Full reasoning in the thread - happy to be argued out of it, and I have offered a version of the underlying fix I do think is right.

Two things to know before re-reading

• The lockfile block changed. The PR body says this branch carries only its own importer entry, which is still true, but that entry now declares date-fns and @vitejs/plugin-react and no longer declares @vitejs/plugin-react-swc. pnpm install --frozen-lockfile re-verified on this branch and on PMM-15326: Mount OM in the PMM app and its navigation #5818 separately. I will update the body.
• formatTimestamp moved from toLocaleString() to a fixed yyyy-MM-dd HH:mm:ss. Deliberate - run timestamps are compared down a column - but it is a visible change and easy to revert if you would rather keep the reader's locale.

Vite plugin and arrow components were applied to this package only; the rest of the tree is still on -swc and function declarations, and those are not this PR's to move.

Screenshots still to come.

Ported five commits from the integration branch, implementing Adamo's UI feedback on PMM-15326 comment 477895 plus two bugs a follow-up review found in that work:

• 34131a5f6 — Inventory: nine quick-filter chips (15m/30m/1h/4h/8h/today/week/month/all) over the server-side date window from PMM-15326: Add the OM API #5813/PMM-15326: Implement the OM service in pmm-managed #5816.
• 669e486c8 — Hosts: Not monitored/Monitored/All filter (defaults to All -- tried defaulting narrower first, reverted after a monitored host vanished from the page on load and read as a sync bug), a Reachable/Unreachable chip replacing raw latency, and bulk row selection wired to live Refresh/Forget actions.
• 598c2c85e — Overview: P/S badges beside the service name (traced state to replSetGetStatus().stateStr, unmapped, ten real values -- amber covers the ones outside Adamo's ask, gray for hidden/delayed is flagged as a separate backend gap rather than faked), mongos's own red badge, Member state column removed from both views.
• cca306294 — fixes the Inventory since window freezing at click time and silently growing past its own chip label the longer a tab stayed open.
• d353526e3 — fixes bulk Forget retrying (and re-deleting) hosts that had already succeeded, and Cancel clearing the row selection it shouldn't have touched.

Fast-forward push, no rebase. tsc --noEmit, oxlint, oxfmt --check clean; 66/66 Vitest tests pass.
