SYSTEM EVENT LOGGING

The ATLAS 550 Event Log is used to log various message types at settable threshold levels. This section describes the entries that may be logged by the system event log.The Event Log’s CATEGORY is particularly important – this is the minimum severity level that must be set in order that the event be logged.

Use caution when changing CATEGORY values 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.

The Event Log is a useful tool for troubleshooting switchboard (or call connection) activities including the viewing of digits received, digits transferred, and ISDN Messages. Since most of the events discussed in the following tables are used primarily during troubleshooting, they should be turned off in normal operation.
