How to see Azure App Service memory usage?

Question

We have an Azure subscription through a Cloud Service Provider (CSP), which causes some limitations on what we can get and see in Azure. Nevertheless, we can see CPU and Memory usage per App Service Plan.

How can we see the same for specific App Services under the plan?

If I see abnormal CPU/memory utilization for the plan, how can I tell which App Service is causing it?

Answer 1

Here are some of the ways to check for memory usage in 2025:

Options 1:

1. Go to any site (app) that's part of the App Service Plan
2. Click on "Diagnose and Solve Problems"
3. Search for "memory usage" in the search box labeled "Search common problems or tools" (at the top of the view)

Option 2:

1. Go to any site (app) that's part of the App Service Plan
2. Click on "Metrics" under "Monitoring" tab in the side bar
3. Select "Memory working set" in the metric drop-down

Answer 2

You can check this under any Site -> scroll down to the "Metrics (App Service Plan)" option. There you will be able to see the metrics across all sites which are in the plan and filter the data the way you want:
