What is SYSLOG ?

The syslog is fundamentally the procedure that created the syslog message. On the off chance that you take a gander at a portion of the syslog messages above, you can see %LINEPROTO which monitors line conventions, %SYS for general framework messages and %LINK for interfaces that went up or down.

The seriousness level is an essential one, it discloses to us how critical the message is. Not everything that occurs on your switch or switch is similarly imperative.

The mental aide is a short code for the message. For instance, "UPDOWN" for interfaces that go up or down. "CHANGED" for when the interface status changes et cetera. These can be valuable on the off chance that you are looking over some syslog messages, searching for specific message sorts.

Syslog Severity Levels

We should investigate the seriousness levels. There are diverse seriousness levels for logging data. An interface that goes down is most likely more vital to know than a message that discloses to us we left the worldwide arrangement. Altogether there are 8 seriousness levels:

0. Emergency
1. Alert
2. Critical
3. Error
4. Warning
5. Notice
6. Informational
7. Debug

The lower the number, the more imperative the syslog message is. Alarm and crisis are utilized when something terrible is going on, similar to when your switch comes up short on memory and a procedure crashes. The basic, blunder and cautioning messages are utilized for imperative occasions like interfaces that go down.
