# Configure silences
|
|
|
|
Silences stop notifications from getting created and last for only a specified window of time.
|
|
|
|

|
|
|
|
- Inhibition rules are not supported in the Grafana Alertmanager.
|
|
- The preview of silenced alerts only applies to alerts in firing state.

## Add silences
|
|
|
|
To add a silence, complete the following steps.
|
|
|
|
1. In the left-side menu, click **Alerts & IRM** and then **Alerting**.
|
|
1. Click **Silences**.
|
|
1. From the **Alertmanager** dropdown, select an external Alertmanager to create and manage silences for the external data source. Otherwise, keep the default option of Grafana.
|
|
1. Click **Create silence** to open the Create silence page.
|
|
1. In **Silence start and end**, select the start and end date to indicate when the silence should go into effect and expire.
|
|
1. Optionally, in **Duration**, specify how long the silence is enforced. This automatically updates the end time in the **Silence start and end** field.
|
|
1. In the **Label** and **Value** fields, enter one or more _Matching Labels_. Matchers determine which rules the silence will apply to. Any matching alerts (in firing state) will show in the **Silenced alert instances** field
|
|
1. In **Comment**, add details about the silence.
|
|
1. Click **Submit**.
|
|
|
|
## Edit silences
|
|
|
|
To edit a silence, complete the following steps.
|
|
|
|
1. In the left-side menu, click **Alerts & IRM** and then **Alerting**.
|
|
1. Click **Silences** to view the list of existing silences.
|
|
1. Find the silence you want to edit, then click **Edit** (pen icon).
|
|
1. Make the desired changes, then click **Submit** to save your changes.
|
|
|
|
## Create a URL to link to a silence form
|
|
|
|
When linking to a silence form, provide the default matching labels and comment via `matcher` and `comment` query parameters. The `matcher` parameter should be in the following format `[label][operator][value]` where the `operator` parameter can be one of the following: `=` (equals, not regex), `!=` (not equals, not regex), `=~` (equals, regex), `!~` (not equals, regex).
|
|
The URL can contain many query parameters with the key `matcher`.
|
|
For example, to link to silence form with matching labels `severity=critical` & `cluster!~europe-.*` and comment `Silence critical EU alerts`, create a URL `https://mygrafana/alerting/silence/new?matcher=severity%3Dcritical&matcher=cluster!~europe-*&comment=Silence%20critical%20EU%20alert`.
|
|
|
|
To link to a new silence page for an external Alertmanager, add a `alertmanager` query parameter with the Alertmanager data source name.
|
|
|
|
## Remove silences
|
|
|
|
To remove a silence, complete the following steps.
|
|
|
|
1. In the left-side menu, click **Alerts & IRM** and then **Alerting**.
|
|
1. Click **Silences** to view the list of existing silences.
|
|
1. Select the silence you want to end, then click **Unsilence**.
|
|
|
|
> **Note:** You cannot remove a silence manually. Silences that have ended are retained and listed for five days.
