I do not understand why you would need to make all services dependent on a check_ping service when the Nagios Documentation states: In the "Theory Of Operation" Chapter, Section entitled: "Determining status and reachability of network hosts":<a href="http://tahoe.examen.com/nagios2/docs/networkreachability.html"></a> <tt>Whenever a service check results in a non-OK status level, Nagios will attempt to check and see if the host that the service is running on is "alive". Typically this is done by pinging the host and seeing if any response is received. If the host check command returns a non-OK state, Nagios assumes that there is a problem with the host. In this situation Nagios will "silence" all potential alerts for services running on the host and just notify the appropriate contacts that the host is down or unreachable. If the host check command returns an OK state, Nagios will recognize that the host is alive and will send out an alert for the service that is misbehaving.</tt> By adding the dependency on a check_ping service aren't you adding another level of complexity that is already handled by default?? -Emmett Leonardo Henrique Machado wrote: <blockquote cite="mida3c20c3005011013394d38bb3f@mail.gmail.com" type="cite"> <blockquote type="cite"> <pre wrap="">I think I'm a little confused about dependencies.
