The nova-network service on labnet1002 is critical and needs to page. As of today, it is configured to do so.
Alas, if the whole system goes down, the icinga PING test will suppress the nova-network service test. And the PING test does not, itself, page. So we'll get pages if the service dies but not if the whole box goes down.
Is there a way to mark a particular host as critical so that we get paged if the PING test fails? If not, we need a way.
