System Log
The system log is a history of all system events (messages) and is used for support issues.
Each message has a timestamp, a source and a severity level.
Severity levels are:
- Emergency
- Alert
- Critical
- Error
- Warning
- Notice
- Info
- Debug
Debug messages are not logged by default. If support requests you, you have to enable logging of debug messages on the log configuration page.
During normal operation there is little need of monitoring the system log. You should consult the system log for messages if the unit is behaving incorrectly, or you have made some configuration but it is not activated. Check then for error messages.
Easiest way of copying the system log to e.g. an e-mail is using Ctrl+A, Ctrl+C
Filter
The Display Filter on the System Log page is for post-grab-filtering - it controls display of already recorded data.
To configure what packets to log in the system log use the Log Configuration page.
Thus for example if you have not enabled “Debug messages in system log” then no debug level entries will be logged. Thus enabling Debug on the Display Filter will not show any such events as they never become logged.
Export
You can export the system log to various receivers (syslog server, SNMP server, e-mail, USB, etc) on the log configuration page.
