Kubexa

work in progressThis site is being written now: pages appear and change as the cluster does. The AI layer is the most incomplete part.

Monitoring stack

What is collected, where it lands, which alerts exist, and how to read them.

Collection

signal component storage
metrics VictoriaMetrics, single node ceph-block, 30 days
logs Vector, node and pod sources 7 days
traces services that instrument themselves best effort

VictoriaMetrics keeps PromQL and costs less per series than Prometheus at this size, so one store answers cross-signal questions without a second query surface.

Alerts

Every alert here has an action attached. An alert without one gets deleted rather than tuned.

  • a certificate expiring inside seven days
  • a Ceph pool or a volume above 85 percent
  • a Postgres replica lagging more than 30 seconds
  • a controller failing to reconcile for more than 15 minutes
  • a node NotReady for more than 5 minutes

CPU sitting high is not an alert. A cluster using its capacity is doing its job.

Dashboards

Three, deliberately: cluster (nodes, pods, restarts), storage (pools, OSDs, volume usage), databases (replication, connections, WAL). A dashboard nobody opens is a maintenance bill disguised as observability.

Access

Grafana is served at grafana.kubexa.tech behind the gateway with Zitadel as the identity provider, so there is no separate password to rotate.
