HI, Our app pool stopped automatically. i dont see huge number of web requests around that time. iNot sure why the app pool stopped. Would we be able to dig it down using dynatrace? would we be able to find the number of transactions around that time? or any other better way to approach this issue? Please share the steps.

Hi Mahendran,

I would suggest starting with the Infrastructure and Process Health dashboards. Initially, from the Infrastructure dashboard, locate your host and open the host health dashboard for the timeframe when your app pool stopped: investigate whether maybe an insufficiency of resources may have contributed to it. From this dashboard, you can then drill down into the actual app pool process and see if there are any process health issues which may have contributed to it.

Finally, you may want to pull some metrics in a custom dashboard to investigate any patterns in behaviour. You can get the number of transactions for that time by charting PurePath Response Time, with the aggregation set to 'count', filtered by the agent monitoring your app pool. Maybe also have a look at the Thread Count for that agent, and possibly more in depth memory metrics (if anything seems out of the ordinary in the process health dashboard).

Regards,

Radu
