 Metrics provide information about the app or the App Service plan's behavior.
 
 For an app, the available metrics are:
 
 | Metric | Description |
 | --- | --- |
-| **Average Response Time** | The average time taken for the app to serve requests, in seconds. |

 | **Average memory working set** | The average amount of memory used by the app, in megabytes (MiB). |
