Troubleshooting with the User Log
The user log is an ASCII file that can be viewed in any editor. It contains a record of system events,
including startup, shutdown and errors. You can use the Logger to view the user log to determine whether
or not the system is functioning properly, as well as for technical support purposes.

The Logging System
Events are logged to one of two log files. After a file reaches maximum capacity, the events logged in
that file are then temporarily archived. New events are then automatically logged to the alternate log file.
When the second log file reaches maximum capacity, the system then reverts to logging events to the
first log file, thus overwriting the temporarily archived information stored in that file.
Basic operations include:
•
Copying the User Log to an external source
•
Viewing the User Log
•
Clearing the User Log
•
Viewing/clearing the User Log counters
