5.1 Logging Overview
The two primary types of logging supported on the 7705 SAR are:
• Event Logging
• Accounting Logs
5.1.1 Event Logging
Event logging controls the generation, dissemination and recording of system events
for monitoring status and troubleshooting faults within the system. Events are
messages generated by the system by applications or processes within the
7705 SAR. The 7705 SAR groups events into four major categories or event
sources:
• Security events — security events are generated by the SECURITY application
and pertain to attempts to breach system security
• Change events — change events are generated by the USER application and
pertain to the configuration and operation of the node
• Debug events — debug events are generated by the DEBUG application and
pertain to trace or other debugging information
• Main events — main events pertain to 7705 SAR applications that are not
assigned to other event categories/sources
The applications listed above have the following properties:
• a timestamp in UTC or local time
• the generating application
• a unique event ID within the application
• a router name identifying the VRF-ID that generated the event
• a subject identifying the affected object
• a short text description
Event control assigns the severity for each application event and determines whether
the event should be generated or suppressed. The severity numbers and severity
names supported in the 7705 SAR conform to ITU standards M.3100 X.733 and X.21
and are listed in Table 29.
