Subject: [Nagios-users] Automatic Host Checks


I have been reading through the docs and I cannot find a definitive
answer to this.  Does Nagios do a ICMP host check automatically?  Is
this something that need to put in the nagios.cfg file?  I have been
defining an ICMP "check-host-alive" command on each host.  Now I think
that Nagios is double ICMP checking all hosts.

Using Plugins For Host Checks 

Using plugins to check the status of hosts may be a bit more difficult
to understand. In each host definition you use the <host_check_command>
argument to specify a plugin that should be executed to check the status
of the host. <em>Host checks are not performed on a regular basis</em> -
they are executed only as needed, usually when there are problems with
one or more services that are associated with the host. 

<emphasis mine ;)>

This directly ties into
