About the failed snapshot: I know what you mean by the red one. But it isn't generated for some reason.
The automated snapshot (everyday around 22:00 hours) is ok (?)
But when I do a manual Apply config, I see this:

The apply configuration fails, and you are rolled back to the "last known good checkpoint", but you don't have any snapshots with config errors (in red color)? Can you go to Admin->Config Snapshots and post a screenshot of this page?

Also, run the reconfigure_nagios.sh script from the command line as root and as nagios, and show us the output:

Code: Select all

cd /usr/local/nagiosxi/scripts
./reconfigure_nagios.sh

su nagios
cd /usr/local/nagiosxi/scripts
./reconfigure_nagios.sh

Re: apply config fail

Post by lmiltchev »

Are you using a proxy? If you are, please follow our recommendations about proxy configuration on our FAQ wiki page here:

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

Make sure you exclude localhost in "/etc/wgetrc", i.e.

Code: Select all

no_proxy=localhost,127.0.0.0/8,10.0.0.0/8,172.16.0.0/12,192.168.0.0/16 # Hosts to exclude from proxying
Can you also run the following command and show us the output:

Code: Select all

ll /usr/local/nagiosxi/scripts/nagiosql*

I got another one on another Xi srver

Code: Select all

Error: Invalid max_check_attempts value for host 'dcf-fr-s07'
Error: Could not register host (config file '/usr/local/nagios/etc/hosts/dcf-fr-s07.cfg', starting on line 14)
Host does not exist anymore. I've tried to writ the config manually via CCM-Write config and so on.
My pending changes are execued allright, but apply config still fails.. (on both errors)

I can't help it, but these 'ghost fails' seem to have increased since version 2014Rx.x

Humor me here for a minute. We have seen issues with sudoer rules on r2.6. Try removing "sudo" from the statement on line #44 in the file:

Code: Select all

/usr/local/nagiosxi/scripts/restart_nagios_with_export.sh
Change:

Code: Select all

    sudo $BASEDIR/manage_services.sh restart nagios
To:

Code: Select all

    $BASEDIR/manage_services.sh restart nagios
Save out. Now remove the host and service config files:

Code: Select all

rm -f /usr/local/nagios/etc/hosts/*
rm -f /usr/local/nagios/etc/services/*
And then try to run reconfigure nagios from the cli:

Code: Select all

cd /usr/local/nagiosxi/scripts
./reconfigure_nagios.sh
Post the output.

Re: apply config fail

Had to edit /etc/wgetrc to get rid of proxy isssues. But after that the above reconfiguration steps worked for me.
Thanks a bunch.

I do, however still have one issue where the apply config reports a host error stating that the host that cannot be a child/parent of itself.
I've obviously looked in the host config. No parents.
I was hoping that above steps would clear this one too, but too bad. still there..

Do you see any config errors when you run the Write Config Tool?

CCM->Write Config Files->Write->Verify

Have you tried deleting the configs via the Write Config Tool and applying configuration?

Delete->Write->Verify->Apply Configuration (if there are no config errors in the previous steps)
