Show Kudu sites in "Metrics per Instance" chart
The "Metrics per Instance" chart accessed from an App Service Plan blade is invaluable for diagnosing load on an app service plan shared between different app services.
The overall CPU / memory load of the ASP doesn't always make sense however, as the app services are not the only things running. If the Kudu web app is running out of control (see https://github.com/Azure/azure-webjobs-sdk/issues/1050 for an example) this is tricky to identify. Showing the Kudu web apps on the "Metrics per Instance" chart would make this much easier.
