service checks are ran before host checks. So, ping service might be down but the host might still be up. It also depends on how many times you specify a service to be checked before it goes to critical state. Nagios will run all service checks before it runs host check.<div> </div><div>Alex <div class="gmail_quote">On Tue, Apr 1, 2008 at 7:48 AM, <<a href="mailto:D.Parise@iaea.org">D.Parise@iaea.org</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;"> -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Dear All, I have configured my hosts with the check-host-alive with check_ipmc and all of them have also the ping service. Now I receive the notifications when the ping is down, but not the notifications for the host down, and I do not understand why. Often the ping do not go down for long, maybe it is not enought to put the host down. The second question is what's the real point to have the ping service configured on all the hosts if the host check is done via icmp.
