Logging Overview
The two primary types of logging supported on the 7705 SAR 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. 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 — events that 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
• the VRF-ID
• 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 25.
