nagios not running host check_command

Hi,
I have a basic nagios setup using the rpms;
nagios-2.0-0.b4.1.1.el3.test
nagios-plugins-1.4-2.1.el3.rf
Its running fairly vanilla minimal.cfg, with a separate hosts file. In
nagios.cfg host checks are enabled;
execute_host_checks=1
I have about 20 servers, for which I have no specific services to monitor, but
which I am interested in their host status, ie the check_command in the host
entry in the hosts.cfg file is set to check-host-alive.
However, it appears that the host check_command is never executed, and
availability for the host is always Undetermined - Insufficient Data 1d 0h 0m
0s 100.000%
Also the status in Host Status detail is always pending, though there are no
other checks configured for this host.
If I explicitly add a check-host-alive for the host in a service configuration,
then the host appears as up in the Host Status Details list, but obviously I
would expect it to appears as UP due to the check_command
Any ideas on whether this is the expected behaviour for the check_command
directive?
Thank,
Tom
