Nagios Logrotation removing notification on rotated files

[jose-martins]

Hello all.

I've been using Nagios on my corporation with great success.
But there's a behavior on logrotation that I not quite understand.

Logrotation is enabled, but no notifications are kept on rotated files.
log_file=/opt/nagios/nagios/var/nagios.log
log_rotation_method=d
log_archive_path=/opt/nagios/nagios/var/archives

For the current day (viewing the log_file), I get all notifications sent.
For any history (pressing the back red arrow), I always get the "No notifications have been recorded in this archived log file".

Any help solving/debugging, would be appreciated.

Are you using the standard Logrotate tool?

[jose-martins]

I'm using Nagios logrotate method, didn't change anything.

How do I even debug such behaviour? Is there any "flag"/anything I can do to see logrotation steps and try and debug why is it not rotating some lines?

Are your logs being rotated correctly? Check the archives:

Code: Select all

ls -la /opt/nagios/nagios/var/archives

If they are there, tail one to make sure they are readable.

[jose-martins]

They are there, and readable.
But they "lost" some information. As if they where filtered when they where rotated.

[abrist]

hmmm. Never heard of that. What type of information is missing from the archived logs?

[jose-martins]

Notifications, for example.

[abrist]

Alright. Are there any notifications logged in the current nagios.log file? Or are the notification logs missing from that file as well?

[jose-martins]

Nope. The current file is all OK. Only the rotated logs are missing the notifications.

Run the following command and post the results in a code wrap. We are going to check logging options in nagios.cfg

Code: Select all

$ cd [path to nagios.cfg dir]
$ cat nagios.cfg | grep log
