Appendix C. Error Log Information
This appendix provides a brief overview of the Error Log and the
associated commands used by the AIX Operating System.
Additional information and detailed descriptions are provided in
the A/X Operating System Commands Reference manual and the
software problem determination part of the Problem Determination
Guide.
The Error Log Information is useful in determining the failing area
of the system unit or the software. Where possible, both
intermittent and permanent failures are recorded in the Error Log.
Intermittent failures of the hardware and software may not be
detected by the diagnostic programs.
The errdemon command is used to start logging error data in the
Error Log.
The errstop command is used to stop the logging of error data in
the Error Log.
The errpt command is used by the AIX Operating System to read
the data in the Error Log and display or print a report from that
data.
The following pages briefly describe the commands and the reports
they produce. See Error Log Command Examples in this appendix
for examples of commands.
