Appendix A
System Event Logging
This appendix describes the entries that may be logged by the system event log. Of particular impor-
tance is the log event’s Category – this is the minimum severity level that must be set in order that the
event be logged.
Most of the events discussed in the following tables are used primarily during troubleshooting and
should be turned off in normal operation:
Use caution when changing Categories from their default levels. If too many sources have their
Category values set too low, the number of messages being logged in a given period can be very
large. If too many messages are being logged too rapidly, system performance can be adversely
affected.
