Logging Overview

The two primary types of logging supported in the OS are event logging and accounting logs.
Event logging controls the generation, dissemination and recording of system events for
monitoring status and troubleshooting faults within the system. The OSgroups events into three
major categories or event sources:

Event control assigns the severity for each application event and whether the event should be
generated or suppressed. The severity numbers and severity names supported in the OS conform to
ITU standards M.3100 X.733 & X.21 and are listed in

Events that are suppressed by event control will not generate any event log entries. Event control
maintains a count of the number of events generated (logged) and dropped (suppressed) for each
application event. The severity of an application event can be configured in event control.
