Syslog messages are free form text, containing 5 types of information:
- message text.
- machine source.
- timestamp.
- facility.
- urgency level.
syslogger accepts the syslog message and generates an event when the facility and urgency level meet the conditions specified in the syslogger section of entuity.cfg. In entuity.cfg, you can limit syslogger to only handle messages from managed devices.
syslogger takes the information from the syslog message and, where the devices are managed by Entuity, uses the Entuity database to identify the device and possibly add additional information, e.g. CPU utilization, buffer rcapacity and mismatches in protocol.
syslog event details has the format:
tag:message
where:
- tag indicates the syslog message type, e.g.:
- %PAGP-5-PORTFROMSTP, a spanning tree messages.
- %LINK-3-UPDOWN, a link up and down (physical).
- %LINEPROTO-5-UPDOWN, a line up and down (layer 2).
- message, the content of the syslog message.
