Description

Below mentioned hpa metrics have been added.

  • kube_horizontalpodautoscaler_metadata_generation
  • kube_horizontalpodautoscaler_spec_max_replicas
  • kube_horizontalpodautoscaler_spec_min_replicas
  • kube_horizontalpodautoscaler_status_current_replicas
  • kube_horizontalpodautoscaler_status_desired_replicas
  • kube_horizontalpodautoscaler_labels

have skipped adding kube_horizontalpodautoscaler_status_condition as it seems to have too many conditions and will increase metric cardinality.

Ref:https://github.com/kubernetes/kube-state-metrics/blob/master/docs/horizontalpodautoscaler-metrics.md

Testing performed
  • ci/build.sh
  • Redeploy fluentd and fluentd-events pods
  • Confirm events, logs, and metrics are coming in
