To Nagios XI Tech Support Specialist:
I am unable to remove hosts or entities as we call it here at our company from the "All Hosts Problems" list. I already deleted them from the Core Config Manager from the Monitoring lists under Hosts and as well as Services, but they keep showing up in the "All Hosts Problems" list. Have I missed another location other than Services to delete them from????

If you deleted some hosts and services from the Core Config Manager but they are still visible, try troubleshooting by following the steps described on our wiki pages:

Also, make sure you the host actually got deleted in the CCM. The CCM spits its errors out at the bottom and not the top so sometimes its easy to miss if there was an error during an operation. Did you delete the services before the host? If you don't do it the proper order, the CCM not delete it due to dependency issues (and show an error at the bottom).

A write was mentioned in your notes or attached info. Where is the "write tool" exactly located for me to manually remove the phantom host or ghost host? Dependency on services does not seem to be the issue. I already removed the services before the host........

Go to Configure->Core Config Manager and click on "Write Config Files" under "Tools" from the left panel menu.

Find the problematic host config file and delete it manually from terminal. For example:
