Doc Text: |
Cause:
When containers have a high (or > 1) restart count, the Kubelet could inject duplicate container metrics into the metrics stream.
Consequence:
This would cause the /metrics endpoint on the Kubelet to throw a 500 error.
Fix:
The fix is to only include metrics of most current (running or stopped) container.
Result:
The metrics endpoint will no longer throw a 500 and allow metrics to flow to Prometheus.
