Silence alerts
Briefly turn off notifications from specific alerts during a maintenance window
Required permission: OperateOPERATOR · ADMIN
During times when you know alerts will fire, such as node maintenance, set a silence so notifications do not flood in. The silence is created in Alertmanager and lifts by itself when the time you set has passed.
- Go to Alerts (경보) → Silence (음소거) tab and fill in the input row. Enter ① the label (default
alertname), ② the value (the alert rule name), ③ the duration (how many hours) and ④ the reason, then ⑤ press Silence (음소거).Silences tab of Alerts — ① label ② value ③ duration (hours) ④ reason ⑤ Silence - The silence appears in the list with its end time. To lift it early, press End (해제).
- Find the rule name in the Alerts (경보) list or on the Rules (룰) tab. Pressing the Silence (음소거) button on an alert's detail screen opens this tab with the values already filled in.
- A silence applies only to your tenant's alerts. The server automatically adds the condition
tenant=<current tenant>, so alerts with the same name in other tenants are not hidden. The list also shows only silences created by your tenant. - A silence blocks notifications from alerts that go through Alertmanager (Prometheus rules, for example
GeoTenantTrainingQueueStalled). Handle alerts the platform creates itself, such as edge monitoring and drift, with Acknowledge (확인) and Resolve (해결). - On installations without Alertmanager connected, "Alertmanager is not configured (Alertmanager가 설정되지 않았습니다)" is shown and you cannot create silences.
