Hi Team,

We need to do a log rotation for directory"/drbd/nagios/var/archives" as the disk is getting filled very often.

Need to know how to do it and will it create any impact or data loss if we do a log rotate on /drbd/nagios/var/archives directory.

Please suggest.

[root@nagios archives]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/centos-root 150G 34G 117G 23% /

Hi

/usr/local/nagios/var/nagios.log
The Nagios Core log, includes checks, notifications, external commands, and events. This file is rotated
daily into the /usr/local/nagios/var/archives folder (default setting in nagios.cfg) by rsyslog.
Logs located in the /usr/local/nagios/var/archives folder are used as the data source for the
Availability and SLA reports. Deleting them would cause these reports to show inaccurate data.

What does this show:

Code: Select all

ls -l /drbd/nagios/var/archives

It should have one log for each day:

Code: Select all

-rw-r--r--  1 nagios nagios   3633 Oct  1 23:10 nagios-10-02-2021-00.log
-rw-r--r--  1 nagios nagios   3633 Oct  2 23:10 nagios-10-03-2021-00.log
-rw-r--r--  1 nagios nagios   3633 Oct  3 23:10 nagios-10-04-2021-00.log
-rw-r--r--  1 nagios nagios   6236 Oct  4 23:16 nagios-10-05-2021-00.log
-rw-r--r--  1 nagios nagios   3633 Oct  5 23:16 nagios-10-06-2021-00.log
-rw-r--r--  1 nagios nagios   3633 Oct  6 23:16 nagios-10-07-2021-00.log

If you do:

Code: Select all

head nagios-11-17-2021-00.log

you can see if the log rotations is being used:

Code: Select all

[1637038800] LOG ROTATION: DAILY
[1637038800] LOG VERSION: 2.0
[1637038800] CURRENT HOST STATE: 192.168.23.84;UP;HARD;1;OK - 192.168.23.84 rta 5.158ms lost 0%
[1637038800] CURRENT HOST STATE: 192.168.23.87;UP;HARD;1;OK - 192.168.23.87 rta 8.070ms lost 0%

You could try using an NFS mount for /drbd/nagios/var/archives but if you have issues with the I/O on the
NFS some of the reports may take a very long time to run .

Thanks
