I have inherited a Nagios installation when the old admin left. He was in the middle of getting the configuration finished so there is a lot of stuff missing.
One of the things he did (and I’m not sure how much of this is default behavior and how much is what he did) is create a hostgroup named “Unallocated” that does not have any members in it. Somehow it’s getting ALL the hosts defined in Nagios. Not only that but when I remove it and run the verification script the script throws errors saying that various hosts are looking for the Unallocated group, even though it’s not in their host.cfg files.
Any help would be appreciated.
