I have taken over an existing MVC website which uses entity framework and hangfire and is hosted on Azure and uses Azure database. Every so often the website times out.

I'm new to Azure portal, entity framework and hangfire.

If I increase the DTU's it clears the timeout issues?

I'm looking for ways of how to diagnose why the website times out. I have added error logging using elmah and checked hangfire but this doesn't give me any further information.

Is there anything in azure portal that can help?
