Nagios Support Forum

Dear Nagios Support Team,

we have an issue with the Verification of the Configuration. If we want to Apply the Configuration we run into the following error:

Applying Configuration

Command submitted for processing...
Waiting for configuration verification...............
Nagios restart command failed.

An error occurred while attempting to apply your configuration to Nagios Core. Monitoring engine configuration files have been rolled back to their last known good checkpoint.

The Write Config Tool can't find any Errors.

And I have been already through this documentation:
http://support.nagios.com/wiki/index.ph ... n_Problems

Please find attached our Nagios profile.txt and the created cmd.txt and reconfig.txt. If you need further information, please contact us.

Thank you very much for your help!

Best regards,

Heiko Bornemann

Can you run the following from the command line
I am thinking that somehow the pid file is missing or maybe we have multiple copies of Nagios running.

Hi,

I am sorry for the late reply.

And I am sorry, but your solution did not work unfortunatly.

the command "killall -9 nagios" couldn't find any processes.

Any other ideas?

Thanks!

Heiko

You're running XI on Fedora 15, which is not a supported platform for Nagios XI. Here's your problem:

System Profile:

Fedora release 15 (Lovelock)

Total Warnings: 0
Total Errors: 0

Things look okay - No serious problems were detected during the pre-flight check
RET: 0
Failed to issue method call: Access denied
Restarting nagios (via systemctl): [FAILED]
OUTPUT=Restarting nagios (via systemctl): [FAILED]
RETURNCODE=6

systemctl is preventing the restart command from working.

Thanks for the replay.

But than I have one more question, please.

Why can I restart nagios than, if I am using "Tools -> Write Config Files" in the Nagios Core Config Manager?

And why is it not supported?

In your System Requirements Fedora is listed.

It would be great, if you could help me.

Thanks!

Could you, please, show us where did you see Fedora listed as "supported" OS? It is not supported and we must rectify this if we made a mistake. Here's what we have on our wiki page and on the Administrators Guide:

http://support.nagios.com/wiki/index.ph ... tributions

http://assets.nagios.com/downloads/nagi ... quirements

Did you look at some other place? Can you provide a URL?

I found it in your pdf file.

Here: http://assets.nagios.com/datasheets/nag ... atures.pdf

On the last page is a System Requirements box.

Everything is working fine, only this "Apply Configuration" button is not.

This document hasn't been updated for a while... We will have to go over it... Regarding the Apply Configuration, our script uses:
It seems like, for some reason, this gets "passed" to systemctl in Fedora 15. We will have to do some digging... Check what you have in the sudoers file - a simple edit may resolve your issue.

Here is the content from the sudoers file.

What needs to be changed, please?
