When I was in the US last week, I commented that it would be great if SharePoint and Project Server made it easier to look up the relevant ULS log entries for a specific correlation id. Of course, the traditional way of viewing these is to navigate to the ULS log location within the farm and view the relevant log file, or to use the excellent ULS Viewer tool to interrogate the files.

Every now and again, I check the epmsource logs to see what people have been searching for on the site. A couple of weeks ago I was surprised to see that people were searching for Correlation ID’s that are raised when an error occurs in Project Server or SharePoint. As a result, I thought a blog post might be appropriate to restate what Correlation ID’s are and how you can leverage them to gain insights into what is really going wrong.
