 ### Prerequisites
 
   - You might need to enable collection of custom metrics for your cluster. See [Metrics collected by Container insights](container-insights-custom-metrics.md).
   - See the supported regions for custom metrics at [Supported regions](../essentials/metrics-custom-overview.md#supported-regions).
 
+### Enable and configure metric alert rules
+
+#### [Azure portal](#tab/azure-portal)
+
+#### Enable metric alert rules
+
+1. On the **Insights** menu for your cluster, select **Recommended alerts**.

+    :::image type="content" source="media/container-insights-metric-alerts/command-bar-recommended-alerts.png" lightbox="media/container-insights-metric-alerts/command-bar-recommended-alerts.png" alt-text="Screenshot that shows recommended alerts option in Container insights.":::
+
+1. Toggle the **Status** for each alert rule to enable. The alert rule is created and the rule name updates to include a link to the new alert resource.

+
+1. Alert rules aren't associated with an [action group](../alerts/action-groups.md) to notify users that an alert has been triggered. Select **No action group assigned** to open the **Action Groups** page. Specify an existing action group or create an action group by selecting **Create action group**.

+
+#### Edit metric alert rules
+
+To edit the threshold for a rule or configure an [action group](../alerts/action-groups.md) for your Azure Kubernetes Service (AKS) cluster.
+
+1. From Container insights for your cluster, select **Recommended alerts**.
+2. Select the **Rule Name** to open the alert rule.
+3. See [Create an alert rule](../alerts/alerts-create-new-alert-rule.md?tabs=metric) for information on the alert rule settings.
+
+#### Disable metric alert rules
+
+1. From Container insights for your cluster, select **Recommended alerts**.
+1. Change the status for the alert rule to **Disabled**.
+
+### [Resource Manager](#tab/resource-manager)
+
+For custom metrics, a separate ARM template is provided for each alert rule.
+
+#### Enable metric alert rules
+
+1. Download one or all of the available templates that describe how to create the alert from [GitHub](https://github.com/microsoft/Docker-Provider/tree/ci_dev/alerts/recommended_alerts_ARM).
+1. Create and use a [parameters file](../../azure-resource-manager/templates/parameter-files.md) as a JSON to set the values required to create the alert rule.
+1. Deploy the template by using any standard methods for installing ARM templates. For guidance, see [ARM template samples for Azure Monitor](../resource-manager-samples.md).
+
+#### Disable metric alert rules
+
+To disable custom alert rules, use the same ARM template to create the rule, but change the `isEnabled` value in the parameters file to `false`.

+# Migrate from metric rules to Prometheus rules (preview) 
+If you're using metric alert rules to monitor your Kubernetes cluster, you should transition to Prometheus recommended alert rules (preview) before March 14, 2026 when metric alerts are retired.
+
+1. Follow the steps at [Enable Prometheus alert rules](#enable-prometheus-alert-rules) to configure Prometheus recommended alert rules (preview).
