Summary

  • Remove PodOOMKilled from pod-alerts.yaml — redundant with OOMKillRateHigh in capacity-alerts.yaml
  • The per-pod rule fires indefinitely on any historical OOM (checks last_terminated_reason state, not rate)
  • OOMKillRateHigh already provides smarter rate-based OOM detection

Changes

  • core/manifests/monitoring/rules/pod-alerts.yaml: Removed PodOOMKilled rule

Test plan

  • ArgoCD syncs monitoring-rules app
  • PrometheusRule resource updates
  • OOMKillRateHigh in capacity-alerts continues to provide OOM coverage

OOMKillRateHigh in capacity-alerts.yaml already covers OOM detection
with a smarter rate-based expression. The per-pod PodOOMKilled rule
fires indefinitely on any historical OOM, generating constant noise.
