Can't remove hosts?

[dawesinnz]

Hey guys - I'm new to Nagios and hit a bit of an issue. Can't find anything on the mighty interweb either. I have 2 hosts that I have deleted the associated services from and then the hosts from within Core Config Mgr, but still show up in the main screen showing all hosts.

Any clues on how to tidy these up?

Cheers
Mike

After you deleted the services and hosts did you Apply Configuration?

[dawesinnz]

I thought I had. So I went in and re-added the hosts, then added services, then deleted the services on one and then the host, then applied the config. That has worked for 1 server but doesn't for the other. I'll re-do and post the exact error shortly. Thanks for your assistance.

Before you apply configuration, you can check if you have any config errors via the Write Config Tool. Nagios cannot start or restart with bad configuration, so it is a good idea to verify your configs, fix any errors that you might have, and then apply configuration. Here is some info on how to use the Write Config Tool:

Hope this helps.

And when i try to delete I get:

Applying Configuration

Command submitted for processing...
Waiting for configuration verification......
Configuration verification 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.

Hey guys - don't worry I have it working now. Still can't delete but have actually got the host doing what I needed so happy it can stay there.
