Refer to The User Log (on page 8-4) for an explanation of commands related to the user log.
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
