"content": "**Everything firing right now**, read from the `ALERTS` series Mimir's ruler writes back (same rules that feed the Discord Alertmanager). This is a read-only view — to **silence or ack**, go to Grafana → **Alerting → Silences** on the *Mimir Alertmanager* datasource. Grafana's native `alertlist` panel can't render an external Alertmanager, so this uses the `ALERTS` metric instead."
