I looked in the logs and found that icinga2 was trying to connect to the wrong database. I corrected this, and now nothing shows up on the web view. Unfortunately I don't have the knowledge to go any further with this. I've only ever setup icinga for use on single hosts. I've never tried to to a setup where there are multiple hosts.

So the checks are working but the checks that are non-tools1 are running on tools1.

I don’t feel comfortable trying to puppitize icinga or icingaweb
