System Logging
System Logging Introduction
The C360 System Logging feature is capable of storing system messages on a device,
outputting messages to the CLI console, Telnet session, or SSH session, and reporting
remotely to a Syslog server. System Logging is an important tool used for routine maintenance,
auditing, and monitoring access to the device.
The components of System Logging include:
● Logging Messages
● Sinks
● Message Facilities
System Logging Messages
System logging messages provide the following information:
● Module ID – The number of the module from which the message originated.
● Event Time – The time the event occurred. The Event Time is included only if a time server
is configured for the device.
● Message Facility – The software sub-system from which the message originated.
● Severity Level – The severity level of the message. Severity levels from the highest
severity to the lowest include: Emergency, Alert, Critical, Error, Warning, Notification,
Informational, Debug
● Message Content – A description of the event.
In order to reduce the number of collected and transmitted messages, filtering options should
be used. The filtering options are based on message classification by Message Facility and
severity. For a specified sink, you can define the threshold severity for messages output by
each Message Facility. Messages with a severity lower than the defined threshold are not sent
to the specified sink.
In addition, the session sink filters the messages using the access level of the user. Only
messages the user is permitted to access are output to the console or Telnet/SSH session.
