Use the Datadog Azure integration to collect metrics from Azure Application Gateway. ## Setup{% #setup %} ### Installation{% #installation %} If you haven't already, set up the [Microsoft Azure integration](https://docs.datadoghq.com/integrations/azure.md) first. There are no other installation steps. ## Data Collected{% #data-collected %} ### Metrics{% #metrics %} | | | | | **azure.network\_applicationgateways.cpu\_utilization**(gauge) | Current CPU utilization of the Application Gateway.
