excellent, thanks for the help.

Understood, thank you for the help.

This issue could be caused by multiple instances of nagios running, but it can be also caused by a config that is "left over" (was not deleted). Did you read the "Host Still Visible In XI After Deletion From the CCM " section on our FAQ wiki page? rm -rf /usr/local/nagios/etc/ho...

Interesting stuff. One observation I have made is that both servers have these files (by both, I mean what I consider the main nagios box and the worker box): mod_gearman_neb.conf mod_gearman_worker.conf Main server: both gearmand and mod_gearman_worker services running.

The fix is to delete the configs and re-write them with an Apply Config. I am still a little confused because the solution to the problem description (which is hosts showing up in the status tables but not at all under Hosts or Services) seem to point to multiple instances of Nagios. This is accord...

Hello, under 'All service problems' I see many legacy systems (i.e. ones we don't use anymore) are failing service checks (obviously).
