Downed hosts not showing on Problems page

Hi,
We have a few hosts that went down and are not showing up in the general or problems view in nagios.
If you click on Hosts under the Problem section you see them all listed there.
Has anyone seen this issue ? and if so can it be fixed ?
Thanks

Hello, are you able to see any hosts in the section where your downed ones disappeared from?

Yes I do.
The hosts that don't show up don't have any service checks assigned to them. So I am wondering if that is the issue here. maybe there is a slight bug in nagios that does not show up anything in the normal dashboard unless it has service checks assigned to it.

Without checks, a host will only show up in the hosts view. So at least assign a secondary ICMP/ping check beyond the host-keep-alive check if you want the hosts populated in the other views.

So this is a design feature then ?
It sounds a bit futile adding in ANOTHER ICMP check when nagios is already doing one when you add a host to the config just to get it to show in the general problems dashboard.

I don't know if it is a feature per se, but more an extension of the logic in core. With just the keep alive check, you are just monitoring host up/down. When the host is down, it will populate the "Problems-->Hosts" list. Almost all usage cases will have more checks than that anyways, which will populate the "Problems-->Services" list when there is an issue.
