All instances are not running in Azure App Service


I am using Azure App Service which hosts application that reads data from Event hub using EventProcessorHost. I have allocated 6 instances(Manual Scaling) to run. I checked the Metrics(CPU Time) in App Service and found only 5 instances are running.

I am getting different instances count for different metrics. Data In metrics shows 6 instances while CPU Time metrics shows 5 instances. I am confused. Please suggest.

Solution

  • the AlwaysOn feature is used to keep your app loaded, particularly when it's not receiving any traffic.

    However, I am aware of numerous instances of AppServices, across a number of Azure Regions, where the metrics were showing the instance count different to the number of instances deployed. This was since yesterday. I believe there have been underlying Azure issues.

    In the Azure Portal, under the menu for your WebApp, you should be able to see the recent health of your WebApp within the 'Resource Health' section.

    I would advise that you raise a ticket with Microsoft, just to be sure.
