+# Alert panels
+
+To view alerts in a dashboard, add **Alerts** panels that show selected alerts. Each panel can display either **Observability** or **Security** alerts with the rule tags and rule types that you select. 
+
+## Create an alerts panel
+
+1. From your dashboard, select **Add panel**.
+2. In the **Add panel** flyout, select **Alerts**. The configuration flyout appears.
+3. ({{stack}} deployments only) Under **Solution**, select either **Observability** or **Security** to specify the type of alerts you want to display. 
+4. Under **Filter by** select either **Rule tags** or **Rule types**. 
+5. (Optional) To use both types of filters, first define one filter, then use the boolean **+ OR** or **+ AND** options that appear to define the second filter.
+5. Click **Save**. Your panel appears on the dashboard.

+## Take action on alerts 
+
+There are several actions you can take on alerts in the alerts panel. Under **Actions**, click the three dots next to an alert to open a menu with the following options:
+
+- **View rule details**: Open the details page for the rule that created the alert.
+- **View alert details**: Open the alert details flyout.
+- (**Active** rules only) **Mark as untracked**: Change the alert's status from **Active** to **Untracked**.
+- (**Active** rules only) **Mute**: Mute alerts from the associated rule.
+
+## Edit an alerts panel
+
+To edit an existing alerts panel, hover over the panel. Three buttons appear:
+
+- **Edit** {icon}`pencil`: Update which alerts appear in the panel.
+- **Settings** {icon}`gear`: Update the panel's title or description, or add a custom time range.
+- **More actions** {icon}`boxes_vertical`: Duplicate, maximize, copy to another dashboard, or remove the panel.
