Problem with Log rotation


#1

I did a search and was unable to find anything on this.

I am having a problem with log rotation, Nagios is creating the new log files but the ‘current’ log file still contains all of the old alert records.

Does anyone have any ideas as to what is happening?

Here is a example of the alert history problem.

How didi you set the log_rotation_method option in nagios.cfg


#3

Sorry, yes log_rotation_method=d. Like I said it creates the new files it just does not clean out the original when it does.


#4

Hm, very strange, haven’t seen this ever…
Have you tried to reinstall Nagios or check the permissions on the nagios.log file and it’s folder?


#5

I have not tried to reinstall nagios, the file is set to:

ls -la nagios.log

-rw-r–r-- 1 nagios nagios 2704710 2008-12-23 08:40 nagios.log
