Can you share your nagios.cfg ?

I have a feeling you are writing performance data files somewhere and not having something reap them

Can you also share the command definitions for these commands

Code: Select all

process-host-perfdata-file
process-service-perfdata-file

Please find command definition,

Code: Select all

define command{
       command_name    process-service-perfdata-file
       command_line    /bin/mv /opt/app/nagios/pnp4nagios/var/service-perfdata /opt/app/nagios/pnp4nagios/var/spool/service-perfdata.$TIMET$
}

define command{
       command_name    process-host-perfdata-file
       command_line    /bin/mv /opt/app/nagios/pnp4nagios/var/host-perfdata /opt/app/nagios/pnp4nagios/var/spool/host-perfdata.$TIMET$
}

Ok, so do you have something reaping the filed out of this directory? like npcd?

Code: Select all

/opt/app/nagios/pnp4nagios/var/spool
What is the output of this command

Code: Select all

ls /opt/app/nagios/pnp4nagios/var/spool|wc -l

Now issue under control, I have stopped httpd and nagios service, delete checkresults directory and created new.

But this issue occurring repetitively. How to avoid and monitor before occurring.

Code: Select all

# ls /opt/app/nagios/pnp4nagios/var/spool|wc -l
18

Oh the files are in the checkresults directory?

Is the path you cleared /opt/app/nagios/var/spool/checkresults ?

Well this looks like it is fluctuating up and down which it should if you have a lot of passive results coming in.
