What does this PR do?

Filters expected HyperShift guest-cluster node bootstrap events from
legacy-node-invariants during a bounded five-minute startup window:

  • Force-deleted pods in kube-system
  • Kubelet system:anonymous authentication failures
  • ErrImagePull pull-QPS-exceeded errors

The filter applies only to external control-plane topology and preserves intervals that continue beyond the startup window.

Why is this needed?

These events can occur while HyperShift guest nodes join and images are pulled during initial cluster setup. They currently appear as node-invariant failures. Later events and unrelated topologies remain evaluated.

Testing

  • go test ./pkg/monitortests/node/legacynodemonitortests
  • go vet ./...
  • Targeted retries of unrelated connectivity tests
  • git diff --check

OCPBUGS-115112

Summary by CodeRabbit

  • Bug Fixes

    • Improved monitoring test evaluation for clusters using external topology.
    • Startup-related node intervals during the first five minutes are now filtered or truncated, reducing false test failures caused by expected startup activity.
    • Handles relevant force-deleted system pods, kubelet authentication failures, and image-pull rate errors while leaving unrelated events unchanged.
    • Improved handling of empty cluster topology and cluster-data lookup errors.
  • Tests

    • Added coverage for startup interval filtering across supported and excluded scenarios.

Walkthrough

The change filters selected node intervals during the first five minutes of external-topology startup. Legacy monitor tests store the collection start time, apply the filter before assertions, and return cluster-data errors.

Changes

Startup interval filtering

Layer / File(s) Summary
Startup interval classification and filtering
pkg/monitortests/node/legacynodemonitortests/startup.go, pkg/monitortests/node/legacynodemonitortests/startup_test.go
The helper removes fully contained startup intervals and truncates intervals that cross the five-minute boundary. Tests cover force-deleted pods, kubelet authentication failures, image-pull QPS errors, and excluded cases.
Legacy monitor evaluation integration
pkg/monitortests/node/legacynodemonitortests/monitortest.go
The monitor test stores the collection start time, validates cluster topology, filters final intervals before assertions, and returns cluster-data construction errors.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~15 minutes

The startup filtering integration preserves cluster-data error handling and scopes filtering to the intended external-topology startup window. No merge-blocking risk remains.

Done. Legacy node monitor evaluation now preserves JUnit results when optional cluster metadata lookups fail, fails early only when topology is unavailable, and returns sanitized errors. Focused tests, go vet ./..., and go build ./... pass.
