I have a web app which is deployed in Azure. Yesterday an alert has triggered mentioning 'Disk Queue Length greater than 5 (Count) in the last 5 minutes' as this is Specific to Service Plan
I've two Apps under the specific Service Plan. I also configured the Application Insights for each App. I need to which App is causing the issue and which operation makes the Disk Queue length getting higher.
So far Investigation I tried the below query in App Insights.
| where timestamp >ago(12hr) |top200by timestamp desc
which gives the operations of the CPU/IO/Memory, but I've no idea how to troubleshoot it to find the root cause
