Nagios Support Forum

Hi Team,

We are seeing issue with Performance Grapher in Nagios XI. We tried to start it from GUI, we are not able to do so. We are using Nagios XI 5.6.8 version. We found that "npcd" service is not running. We tried to restart the service but, unable to do it. Below is the error:

[root@eu2napu003 hosts]# systemctl restart npcd.service
Job for npcd.service failed because the control process exited with error code. See "systemctl status npcd.service" and "journalctl -xe" for details.
[root@eu2napu003 hosts]#

We checked the status as below:

[root@eu2napu003 hosts]# systemctl status npcd.service

I checked the perfdata.log file as well:

We referred to https://support.nagios.com/kb/article.php?id=9 as well and made the changes accordingly, still the issue persists.

Please help us on the same.

Thanks in advance!!

You're getting the error above that is stopping it from starting, can you post the output of the following so we can see what is erroring on line 146

Hi,

PFB the output for cat /usr/local/nagios/etc/pnp/npcd.cfg command:

Hmm, that looks normal, Can you post the output of the following commands

Hi,

That's weird you are missing a directory

Lets run the following

Hi,

We have created the missing directory, its working now. We are good to close the ticket.
Thanks a lot!!

Hi,

We checked the graphs after starting npcd service.
We are not able to see any graph data. Do we need to perform any additional steps?

It may take a bit for them to appear, if you still have none, can you get a profile.zip from Admin -> System Profile and PM it to me for inspection

thanks

Hi,

We can see the graphs now.
We are good to close the ticket.

Thanks a lot again!!
