AUTO-003 HPA target workload or metrics issue

Summary

An HPA targets a workload (scaleTargetRef) that does not exist or is invalid, or the metrics it uses are unavailable. The HPA cannot scale correctly.

Severity

Warning

Example

N/A

Symptoms

  • Report shows: HPA target workload or metrics issue
  • HPA status shows no scale target or metric errors

Resolution

  1. Verify scaleTargetRef (apiVersion, kind, name) points to a valid Deployment, StatefulSet, or other scalable resource
  2. For resource metrics ensure metrics-server is running and pods have requests set
  3. For custom/external metrics ensure the metrics API and adapters are installed and returning data
  4. Check HPA events: kubectl describe hpa <name> -n <ns>
