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
