perfdata directory size increases rapidly

[sandeepatil]

We are facing issue with perfdata directory. Directory size increases automatically and causes to disk full issue.

Please share solution for the same.

Are you talking about the /usr/local/nagios/share/perfdata/ or some other directory?

How large is your Nagios XI instance (number of hosts/services)?

How much room do you have on the hard drive?

Code: Select all

df -h

Is this a physical server or a VM? If this is a VM, you could resize it, by following our official documentation on the topic:

https://assets.nagios.com/downloads/nag ... M-Disk.pdf

[sandeepatil]

perfdata location is "/usr/local/nagios/var/spool/perfdata"

Number of hosts/services: 1000/68000

This is a VM server.

Observed this issue facing ones in a week, currently data deleting manually.

If there are way too many files in "/usr/local/nagios/var/spool/perfdata", this means that npcd is not running and not processing these files.

It is possible that the load on the server is too high - higher than the load_threshold value, specified in the /usr/local/nagios/etc/pnp/npcd.cfg file (10.0 by default). I would recommend that you first find out what is causing the high load (if this is the case) and fix the issue. You can also increase the load_threshold's value to a higher number and restart npcd:

Code: Select all

service npcd restart

Note: The value of 10.0 is meant for 1 core CPU. You could use 20.0 for dual core, 40.0 - for quad core, etc. Make sure you have enough resources before increasing the value.

If you don't have way too many perfdata files in the "/usr/local/nagios/var/spool/perfdata" directory, ncpd *may* be able to *catch up*, and process the files. If however, you have thousands of files in there, you will have to delete/recreate the directory.

Example:

Code: Select all

cd /usr/local/nagios/var/spool
rm -rf perfdata
mkdir perfdata
chown nagios.nagios perfdata
chmod 755 perfdata

Only the "old" perfdata (the files that are currently in the "/usr/local/nagios/var/spool/perfdata" directory) will be lost.

Hope this helps.

Surely this details help us.

Please share how to stop perfdata generation.

If you don't want to use performance data simply do the following
edit /usr/local/nagios/etc/nagios.cfg
change

Code: Select all

process_performance_data=1

to

Code: Select all

process_performance_data=0

save
restart nagios

Code: Select all

service nagios restart

We done change as you suggested, till now Nagios XI working fine.

You can close the thread.

If same issue facing again, we will create new thread.
