Observability
Grafana
Dashboards for the metrics Prometheus collects
What it does
Grafana turns time-series metrics into dashboards, so cluster and application health can be read at a glance instead of queried one metric at a time.
How it runs here
Runs in the monitoring namespace with Prometheus configured as its default data source, and its dashboard JSON is provisioned from a ConfigMap rather than clicked together by hand. Dashboard state itself lives on a small Longhorn-backed volume.

Why I chose it
Dashboards provisioned from Git can be rebuilt on a fresh cluster and are reviewed like any other manifest change.
