SharePoint 2010 itemadded event receiver - how to check logs?

Question

I have created a custom SharePoint 2010 Item added event receiver on a document library. I also log all exception which might be fired during this event receiver. This event receiver fires perfectly fine almost all of the times. There are, however, only a few cases during which the event receiver does not fire. and since the event receiver does not fire I don't see any exception log. These types of events are scattered and not concentrated on a particular timespan of the day.

My question is whether there is some log that I can check on a SharePoint server that will tell me why the event receiver did not fire or probably what went wrong. Thanks in advance.

Answer 1

In my experience, event receivers will just stop when an uncatched exception occurs. So they will not log exceptions themselves.

What you should do is make your event logic exception-proof, so catch everything you can and log it yourself to the ULS.
