Nagios Support Forum

Hi

I have successfully installed PNP4Nagios 6.0 and added host/service details to get the graph but it is not displaying any graph.

When I try to check the configuration, I am getting the following error:

CRIT] Command looks suspect (/bin/mv /usr/local/nagios/var/service-perfdata /usr/local/nagios/var/spool/xidpe/$TIMET$.perfdata.service)

Following is my commands.cfg and nagios.cfg configuration details. Is there anything should I change:

Commands.cfg
============

define command {
command_name process-host-perfdata-file-bulk

}

define command {

command_line /bin/mv /usr/local/nagios/var/host-perfdata /usr/local/nagios/var/spool/perfdata/host-perfdata.$TIMET$
}

define command {

Is the system you installed PNP4Nagios an Nagios XI server or an Nagios Core server?
The Nagios XI server should already have PNP4Nagios installed.
Can you login to the server as root, run the following and post the full output?

Yes, I am using Nagios XI server.

Please find the command output below:

/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg

[root@INTRVSUK-NG01 ~]# /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg

If you're using XI, you will need to use the built in version of PNP4Nagios which is 4.x. At this time, 6.0 is not supported.

OK, How to roll-back to version 4.x

We don't really have rollback instructions documented since we don't support other versions, but you can try the following:
I would strongly recommend taking a VM snapshot first if you can, otherwise an XI backup:

Thank you

Please let me know if it possible to use any external plugin like Nagiosgraph in Nagios XI

Nagios XI already has graphs built in, what exactly are you looking to accomplish?

Using PnP4nagios like tool we can see Host, memory, CPU, Disk, Uptime and Ping utilization of multiple servers in same page.
When we try to get the same info from Nagios Xi (Graphs - Performance Graphs) it displys only host graph details.

E.g:
If I type a name INTRN in host selection option under "Performance Graphs", then it will display only Host graphs for all host starting with the name INTRN.

The same when I search from PnP4nagios then it will display all graphs (Host, memory, CPU, Disk, Uptime and Ping) for all host starting with the name INTRN. We configure like below in the PNP4nagios configuration file:

Another advantage is we can create a seperate user account in Pnp4nagios for customer use, using this customers able to verify the performance graphs. Through this way we can avoid giving direct access to Nagios XI console for users.

Is it possible to use the same features in Nagios Xi ?

While it may be possible, I don't think we can support it.

If you're looking for graphs on a service level, you should still be able to. Are you running into issues seeing this? Attached is a screenshot of the service 'current load' for my localhost machine.
