Exceptions not showing up in Application Insights

Question

We've just installed Application Insights on our server.

Everything seems to be working fine, but exceptions thrown on the server is not showing up in the portal.

We're logging exceptions with our custom tool, but we wanted to be able to see them in AI too, especially the unhandled ones.

It's a plain installation of the AI agent, on a Windows Server 2012.

Answer 1

There is a blog post that describes what is collected out of the box and what you need to do in other cases: http://blogs.msdn.com/b/visualstudioalm/archive/2014/12/12/application-insights-exception-telemetry.aspx

Answer 2

AI will not see the exceptions that you may have handled in any global exception handlers. I suspect that may be contributing to what you find. If you do use global exception handlers, you could use the TrackException from AI SDK in the handler, that will then send them to AI.
