Hi All,

One of our web apps triggered 2 http monitor alerts a couple weeks back, I have tried investigating into what could of caused it but could not find much, see the below screen shots of the triggered alert:User's image

Anyone have any ideas to how i can investigate into why these alerts were caused?

We have not had any recently but of course need to make sure we can prove why these happened.

Kind regards,

Ben

    Hi @Ben Woodman

    I would suggest reviewing Tutorial: Troubleshoot an App Service app with Azure Monitor for suggestions on how to monitor your app service. The AppServiceHTTPLogs will help isolate which request(s) resulted in any 5xx/4xx errors. But also enabling application insights in addition will give you further insights into what led to a 5xx HTTP error code in the first place. Also, look at Diagnose and solve problems blade can also help you further investigate application errors you're seeing.
