When I look at the scheduling queue - only services are listed to be
scheduled (whereas before it used to include the hosts as well - the
service column was blank for host checks.)
The host checks definitely are longer than a minute - so it has taken
effect from the previous config - in the view config, 'enable active
checks' reads 'No' for all hosts.
Can you see anything wrong here - this is a status printout for one of
the hosts:
Host Status:
UP
