Grafana

Dashboards and visualization for BlumeOps observability.

Quick Reference

Property	Value
URL	https://grafana.ops.eblu.me
Tailscale URL	https://grafana.tail8d86e.ts.net
Namespace	`monitoring`
Helm Chart	grafana (mirrored to forge)
Values	`argocd/manifests/grafana/values.yaml`

Authentication

Grafana supports two login methods:

SSO via authentik — OIDC login through Authentik (auth.generic_oauth). Users click "Sign in with Authentik", authenticate at Authentik, and are redirected back as Admin.
Local admin — break-glass login using the password from 1Password ("Grafana (blumeops)"). Always available if Authentik is down.

The OIDC client secret is injected via external-secrets (grafana-authentik-oauth secret in monitoring namespace).

Datasources

Prometheus	prometheus	`prometheus.monitoring.svc.cluster.local:9090`
Loki	loki	`loki.monitoring.svc.cluster.local:3100`
