Can't get Nagios Core to work with PNP4Nagios

Post by Sholmo »

Hello,

I've read thru some similar topics on this forum but haven't found an answer.

Both Nagios and PNP installed with yum. I think I have set everything up correctly yet on ..1/pnp4nagios I'm greeted with:

Code: Select all

PNP4Nagios Version 0.6.25
Please check the documentation for information about the following error.
perfdata directory "/var/lib/pnp4nagios/" is empty. Please check your Nagios config. <a href="http://docs.pnp4nagios.org/faq/3">Read FAQ online</a>

file [line]:
application/models/data.php [109]:
And tbh I'm out of ideas. I'm gonna dump (hopefully) all related cfgs.

Re: Can't get Nagios Core to work with PNP4Nagios

Post by bwallace »

Thanks for all of the details, but what OS/version is the Nagios Server?

For starters, I'm curious to see if npcd is running on it. Could you post the output of ps -ef | grep npcd

If it is not running can you start it ?
service npcd start

Have you checked some of the items which pnpfornagios recommends?

https://docs.pnp4nagios.org/faq/3
https://docs.pnp4nagios.org/pnp-0.6/verify_pnp_config

Also, could you post /etc/pnp4nagios/npcd.cfg

Are you trying to setup your server using bulk mode with NPCD?
If so, it looks like the commands are defined wrong.
Here is the example from the PNP4Nagios web site.
https://docs.pnp4nagios.org/pnp-0.6/con ... _with_npcd

Code: Select all

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

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

Thank you for your reply.

Now I'm kind of lost with paths you have posted, only instances of *-perfdata on my system (according to find ;) ) are:

Code: Select all

/var/lib/pnp4nagios/host-perfdata
/var/log/pnp4nagios/host-perfdata
/var/log/pnp4nagios/service-perfdata

This is going to vary based on how you installed pnp4nagios, as we did not write pnp4nagios it is a bit difficult to support. Did you follow a specific guide when setting up your graphing?
