Host Information Not Available


Hey Guys,

I have a problem with some of my hosts not appearing on the Host Pages.
It will sometimes appear and show that they are active, then they will completely disapear.

On the status map page all the hosts show up, but it shows them greyed out. While they are Grey’d out the mouse over shows Host Information Not Available.

I must have missed something somewhere for these hosts or something?
Has anyone seen this in there world?

Any help is greatly appreciated.



Yes, you have made changes to your config files, but you didn’t restart nagios, or you have more than one nagios running. Reboot your pc.
