 # How to update Azure Monitor for containers to enable metrics
+
 Azure Monitor for containers is introducing support for collecting metrics from Azure Kubernetes Services (AKS) clusters nodes and pods and writing them to the Azure Monitor metrics store. This change is intended to deliver improved timeliness when presenting aggregate calculations (Avg, Count, Max, Min, Sum) in performance charts, support pinning performance charts in Azure portal dashboards, and support metric alerts.

 Either process assigns the **Monitoring Metrics Publisher** role to the cluster’s service principal so that the data collected by the agent can be published to your clusters resource. Monitoring Metrics Publisher has permission only to push metrics to the resource, it cannot alter any state, update the resource, or read any data. For further information about the role, see [Monitoring Metrics Publisher role](../../role-based-access-control/built-in-roles.md#monitoring-metrics-publisher).

+Before you start, confirm the following:

 If you choose to use the Azure CLI, you first need to install and use the CLI locally. You must be running the Azure CLI version 2.0.59 or later. To identify your version, run `az --version`. If you need to install or upgrade the Azure CLI, see [Install the Azure CLI](https://docs.microsoft.com/cli/azure/install-azure-cli).
