Nagios Support Forum

Ok cool thanks.

I've run the update, it;' failed on the config again , not the update itself by the looks of it but loading the config.

Full backup / upgrade output attached.

So at this point, am I right in thinking the cleanest way out of this is to delete the offending host and re-create?

You could either delete it of verify that the host is setup correctly for that service.
You can run this to verify your config files are good.

Ok thanks

This is the output from the UI after a failed 'apply config' :

***> One or more problems was encountered while processing the config files...

Check your configuration file(s) to ensure that they contain valid
directives and data defintions. If you are upgrading from a previous
version of Nagios, you should be aware that some variables/definitions
may have been removed or modified in this version. Make sure to read
the HTML documentation regarding the config files, as well as the
'Whats New' section to find out what has changed.




And then this is the verify output:

Things look okay - No serious problems were detected during the pre-flight check
[root@localhost ~]#

Please run this command:
Then try to run an apply configuration from the web interface and post the full output, I want to see if it gives us any further details.

Output attached.

This is where it is failing:

Error: Failed to expand host list '15GSRicoh1' for service 'Printer Status' (/usr/local/nagios/etc/services/Printer Status.cfg:14)

Go Into CCM
Find the "Printer Status" service
Disable it
Tools > Write Config Files
Click the Delete button
It will say "Successfully deleted all Host / Service Config Files"
Click the Write Button
It will show an output of all the files it creates
Click the Verify button
The output should end with "Total Errors: 0"

Do you get 0 errors?

If you don't please go and resolve the highlighted problem and then perform the steps above again (quickest way is to disable the service it's complaining about).

If you don't have any errors what happens when you Apply Config?
Quick Tools > Apply Configuration
Click the Apply Configuration button

Ok so a colleague picked this up and had come across the problem before.

He went into the service config screen and checked the attached hosts, which I had already done, however I cancelled out and he hit apply as he had found this necessary before in a similar situation. Essentially this rewrites the file I guess, or lists it for re-write.

That and he removed the renamed host from it's group, again hit apply and then added it back in.

This removed the ghost entry and the config is now clean and applied.

I guess the situation arose due to the way we attach a service to multiple hosts, not directly but through groups. If you want me to provide config snapshots etc so you can test and try to re-prodcue the bug in order to try and remove it then I'm more than happy to provide those.

Otherwise thanks and case closed
