The deploy script already enables flow control via the
ENABLE_EXPERIMENTAL_FLOW_CONTROL_LAYER env var on the EPP. Patching
the EPP with --config-file on v0.5.0-rc.1 causes it to restart and
break Gateway routing (HTTP 500). The scale-up latency test proves
the Gateway works when the EPP is left untouched.

- Skip ensureEPPConfig() call so the EPP is not modified
- Restore direct vLLM fallback as safety net if Gateway still fails
- Keep EPP config helpers in codebase for future use
- All EPP queue metric sampling is retained

Made-with: Cursor
The deploy script sets ENABLE_EXPERIMENTAL_FLOW_CONTROL_LAYER env var
on the EPP. Using --config-file with featureGates: [flowControl]
caused a conflict on v0.5.0-rc.1 that broke Gateway routing (HTTP 500).

New approach:
- Use --config-text to pass EndpointPickerConfig inline (no volume mount)
- Remove the deprecated ENABLE_EXPERIMENTAL_FLOW_CONTROL_LAYER env var
  since config-text featureGates supersede it
- Wait for Gateway health after EPP rollout (5min timeout)
- Gateway is now a hard requirement (no fallback to direct vLLM)
- Scorer weights: queue=2, kv-cache=2, prefix-cache=3

Made-with: Cursor
The Helm chart already deploys the EPP with --config-file pointing to
its own ConfigMap (with scorer weights 2/2/3). Adding a second
--config-file or --config-text flag broke the EPP and caused Gateway
HTTP 500.

New approach:
- Find the EPP deployment's existing ConfigMap volume
- Update the ConfigMap data to add featureGates: [flowControl]
- Trigger a rollout restart via annotation (no arg/volume/env changes)
- Wait for Gateway health after EPP restart
- Gateway is a hard requirement — no fallback to direct vLLM

  • Scaler: prometheus-adapter
  • Workflow run

The CI workflow sets E2E_TESTS_ENABLED=true, which causes install.sh
to already configure the EPP with:
- Image v0.5.0-rc.1
- ENABLE_EXPERIMENTAL_FLOW_CONTROL_LAYER=true env var
- ConfigMap with scorer weights queue=2, kv-cache=2, prefix-cache=3

Any modification to the EPP (adding featureGates to config, adding
--config-text, etc.) conflicts with the existing env var and breaks
Gateway routing (HTTP 500).

Replace ensureEPPConfig with verifyEPPConfig that only inspects and
logs the EPP state without modifying it. Gateway connectivity is
validated with a 5-minute retry before benchmark starts.

The Gateway returns HTTP 500 with empty body even when EPP is correctly
configured (flow control enabled, weights 2/2/3, pod Running/Ready).
This is a pre-existing infrastructure issue — not caused by our EPP
modifications.

Add diagnostics to capture in a single CI run:
- EPP pod logs (last 50 lines) after failure
- Gateway/Istio pod logs (last 30 lines)
- All service ports (not just first port)
- InferencePool and InferenceModel resources (via unstructured client)
- Verbose curl output with response body and debug headers

The cluster's Istio 1.29 only watches inference.networking.k8s.io/v1
InferencePool resources, but the v0.3.0 llm-d guide creates them with
inference.networking.x-k8s.io/v1alpha2. This caused Istio to ignore the
InferencePool entirely, resulting in cluster_not_found errors from Envoy.

install.sh now auto-detects when the cluster supports the v1 CRD and
patches the gaie values before helmfile deploy. The HTTPRoute backendRef
group is also updated to match.

- HPA test now creates VA(min=1, max=2, cost=10) + HPA(min=1, max=10)
  to match colleague's setup instead of pure CPU-based HPA
- WVA test cost changed from 30.0 to 10.0 for consistency
- Added model_id, va_config, hpa_config, achieved_rps, error_count,
  incomplete_count fields to result JSON
- Enhanced PDF reports with detailed autoscaler configuration section,
  error/incomplete request tracking, and achieved RPS
- PR comment table now includes failed/incomplete requests and RPS rows

Made-with: Cursor
The external metrics API (prometheus-adapter) can be transiently
unavailable, causing all benchmarks to fail. Change the check from
a hard failure to a best-effort warning with diagnostics, so the
benchmark runs and collects data even when HPA cannot scale.

@llm-d llm-d deleted a comment from github-actions bot Apr 3, 2026
KEDA on the OpenShift cluster continuously reclaims the
external.metrics.k8s.io APIService, preventing prometheus-adapter
from serving wva_desired_replicas. The existing guard only ran
during the deploy step and was dead by the time tests started.

Add a background guard loop that re-patches the APIService every
8 seconds during the actual benchmark run so HPA can scale.

The cluster already has a working prometheus-adapter setup in
workload-variant-autoscaler-monitoring with wva_desired_replicas
rules configured. Using SCALER_BACKEND=prometheus-adapter was
deploying a second adapter and re-patching the APIService, which
then got reclaimed by KEDA, breaking all external metrics.

Switch to SCALER_BACKEND=none to preserve the existing working
external metrics API setup.

Made-with: Cursor
The throughput/ttft/itl fields use omitempty in Go — when GuideLLM
metric extraction fails, these keys are absent from the JSON results.
Add a safe accessor helper and use .get() throughout the plotting
code to handle missing fields gracefully.

Made-with: Cursor
The APIService guard patch was failing with:
  "spec.insecureSkipTLSVerify: Invalid value: true: may not be
   true if caBundle is present"

KEDA sets a caBundle when it reclaims the APIService, which is
mutually exclusive with insecureSkipTLSVerify=true. Adding
"caBundle": null to the merge patch clears it before setting
insecureSkipTLSVerify, matching the state that worked on April 2.

Also switches SCALER_BACKEND back to prometheus-adapter and
re-adds the APIService guard to the CI run step.

Made-with: Cursor
- TTFT mean in PR comment showed "ms" but value was already divided
  by 1000 (should be "s")
- Achieved RPS was always 0.00 because GuideLLM may not expose
  rate.completed_rate; add fallback: completed_requests / duration

The benchmark was deploying vLLM with --max-num-seqs=5 (only 5 concurrent
requests per pod), causing 2-3% KV cache utilization and ~1 RPS instead of
the expected 60-100% KV cache and ~9 RPS. Removing this allows vLLM to use
its default (256), matching the colleague's benchmark configuration.

Also aligns WVA saturation thresholds (kvSpareTrigger, queueSpareTrigger)
to chart defaults (0.1, 3) to match the colleague's setup.

V1 analyzer scales by +1 replica per 30s cycle and blocks during pod
transitions, limiting scaling to ~3 replicas in a 600s test. V2 uses
demand-based calculation (ceil(requiredCapacity / perReplicaCapacity))
and can jump to the needed replica count in one decision, matching the
colleague's benchmark behavior.
