The system log contains information on background processes and errors that occur asynchronously. You can view the system log by going to the /systemlog.aspx page. The log consists of multiple lines listed chronologically. Often the messages are cropped to fit on the screen and can be expanded by clicking the ellipses.

You can clear the system log by adding &clear=true to the end of the request.

The system log will be capped at about 1000 lines, after that older entries will be cropped.
