What is the purpose of cleaner.log files located in "/usr/lo

[skywalker]

Hi,

We have a system running nagios XI 2014 R1.2. Sometime The filesystem is full.
So, I excuted the find command in linux to find a reason.

root@nagiosxi var]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/vda2 9.7G 9.3G 0 100% /
tmpfs 939M 0 939M 0% /dev/shm
/dev/vda1 194M 34M 151M 18% /boot

[root@nagiosxi var]# find /usr -type f -size +1048576
/usr/local/nagiosxi/var/cleaner.log-20140629
[root@nagiosxi var]# ls -alh /usr/local/nagiosxi/var/cleaner.log-20140629
-rw-r--r-- 1 nagios nagios 4.9T 2014-06-30 09:26 /usr/local/nagiosxi/var/cleaner.log-20140629

As a result of filesystem Full, we can't access the web pages because we can'nt access db.
The strange strings(^@) are included in this files.

What is the purpose of cleaner.log files located in "/usr/local/nagiosxi/var/" ?

The "cleaner.log" logs various cleanup jobs that are run on a cron schedule (removing old nom checkpoints, nagiosql backups, etc.).

Code: Select all

grep cleaner /etc/cron.d/nagiosxi

You shouldn't be concerned with the cleaner.log, but with the fact that you are running out of disk space...

You can delete old files in the "/var/log" directory and sub-directories. You can also delete whatever you don't need in the /tmp/" directory. Maybe you have some old backups that you can delete in "/store/backups/nagiosxi".

After you clear some room, add more disk space to your Nagios XI server. Please, review our Nagios XI - Resizing the VM Disk SIze" document here:

http://assets.nagios.com/downloads/nagi ... M_Disk.pdf

Note: Almost always, when you run out of disk space, you will end up with database errors. You will need to run our database repair script to fix corrupted tables:

Code: Select all

cd /usr/local/nagiosxi/scripts
./repairmysql.sh nagios
./repairmysql.sh nagiosql
