In the Grafana menu, click the **Alerting** (bell) icon to open the Alerting page listing existing alerts. 2. On the Alerting page, click **Silences** to open the page listing existing silences. 3. From Alertmanager drop-down, select an external Alertmanager to create and manage silences for the external data source. Otherwise, keep the default option of Grafana. 4. Click **New Silence** to open the Create silence page. 5. In **Silence start and end**, select the start and end date to indicate when the silence should go into effect and expire. 6. Optionally, in **Duration**, specify how long the silence is enforced. This automatically updates the end time in the **Silence start and end** field. 7. In the **Name** and **Value** fields, enter one or more _Matching Labels_. Matchers determine which rules the silence will apply to. 8. In **Comment**, add details about the silence. 9. In **Creator**, enter the name of the silence owner or keep the default owner. 10. Click **Create**. ## Edit silences To edit a silence, complete the following steps. 1. In the Grafana menu, click the **Alerting** (bell) icon to open the Alerting page listing existing alerts. 2. Click **Silences** to view the list of existing silences. 3. Find the silence you want to edit, then click **Edit** (pen icon). 4. 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 Grafana menu, click the **Alerting** (bell) icon to open the Alerting page listing existing alerts. 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.
