Summary

Documents the Cluster metrics view on the Infrastructure dashboard, which now charts CPU, memory, and storage for Porter's in-cluster Prometheus stack in addition to the existing Ingress NGINX charts.

Changes

  • Added a Cluster metrics section to cloud-accounts/cluster-observability.mdx describing the metrics picker
  • Documented the Ingress NGINX arm (CPU, memory, request rate, latency, status codes)
  • Documented the new Prometheus arm (prometheus-server CPU/memory/storage, kube-state-metrics CPU/memory) with a note that storage is TSDB size, not PVC utilization
  • Called out that gaps during a Prometheus outage are expected since the charts are served by the Prometheus they chart

Context

Triggered by porter-dev/code#7280, which adds the Prometheus arm to the cluster metrics picker to help operators diagnose in-cluster Prometheus OOM and disk-fill incidents.
