i have deleted services of a particular node that i am monitoring but the services are still visible in the service detail link.....
i ran the repair database script but still no luck

Posted: **Thu Mar 14, 2013 12:34 pm**

How did you delete the services? Did you delete them from the command line? Or through the Core Config Manager and Applying configuration.

i deleted them from core config manager.
i have applied the configuration as well

What version of XI are you running? There was a bug with a few previous versions where a change of the "config name" of a host or service would spawn ghost copy that would have to be removed by hand. It was resolved in 2012R1.3, but any "ghost" configs still have to be removed manually from the CLI.

To remove the "ghost service", do the following:

Code: Select all

root@localhost$ cd /usr/local/nagios/etc/services

This directory contains the cfg files written out by XI when you click "Apply Configuration". Get a listing of the directory and you should find the ghost service. Remove it.

Code: Select all

root@localhost services$ ls -la
root@localhost services$ rm <name of ghost service>

Now, before you "Apply Configuration" in XI or restart the Nagios server, try to "Write Configs to File". You will find this option in the CCM under "Tools" in left hand nav pane. Once they are written, click "Verify". If verification fails, you may have missed a ghost service cfg or you have other configuration problems. The output from the "Verify" button is in invaluable here.

If "Verify" fails DO NOT restart Nagios or "Apply Configuration". This will revert your configuration to the broken state (and subsequently write the ghost cfg files back to disk) . Instead, look for hints to the offending service or host in the verification output. Once you have fixed any new issues, "Write" and then "Verify" the config once again. You may have to "Write" and then "Verify" multiple times to hunt down all the issues/ghosted files.

Only "Restart" Nagios once all verification errors have been resolved (warnings do not need to be resolved to fix this issue). If Nagios restarts cleanly, "Apply Configuration" in XI. This will save a new, working configuration snapshot for any future configuration failures to roll back to.

Now restart nagios.

Code: Select all

root@localhost hosts$ service nagios restart

If all checks out and your ghost host issue is fixed, now would be a good time to upgrade to 2012R1.3 if you have not already. Let me know if this solved your issues or if you have any other related problems.

Make sure you do not have multiple instances of Nagios running:

Code: Select all

service nagios stop
ps -aef | grep nagios
killall nagios
service nagios start

Run the following from the cli and post the output here in code wraps:

Code: Select all

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

i see the following processes after i stop nagios
do you want me to kill all these
