1. To enable runtime metrics, KubeBlocks must be deployed with ENABLED_RUNTIME_METRICS=true, set following values when install KubeBlocks through HELM

# values.yaml
serviceMonitor:
  enabled: true
  goRuntime:
    enabled: true

2. To check the metrics/

curl <kb-pod-ip>:8080/metrics

Then you can customize the dashboard to your needs based on these metrics.
