I have them all setup as active hosts that nagios pings to indicate they are up. Since they are all behind firewalls all I'm doing for host status is in fact just pinging the firewall. I'm a little confused about using passive checks and not sure if this is the right way to go about doing what I want. I monitor the firewall and know that is up, and for all those hosts behind I'm just pinging the fw, no need to do that. I use nrpe or nsclient to monitor the services and really that's all I need. Can someone point me in the right direction so I can stop the active host status pings for all hosts behind the firewalls. </blockquote><div> If you dont want to open up ping on the firewalls you could ether have a dummy hosts check (a check that just returns 0) or have nrpe as the hosts check (eg a check that just checks if nrpe is responding, again an nrpe check that just returns 0 ) client nrpe command like this command[check_nrpe_alive]=/patch/script/that/<a href="http://returns.0.sh">returns.0.sh</a> Nagios command: define command{ command_name check_nrpe_alive command_line $USER1$/check_nrpe -H $HOSTADDRESS$ -C check_nrpe_alive } define host{ name behind_firewall use generic-host hostgroups +behind_firewall register 0 } then a use clause in your host config of behind_firewall Ritchie -- <-- <a href="http://23.me.uk/2" target="_blank">http://23.me.uk/2</a> --> <--Time flies like an arrow; fruit flies like a banana. --> </div><div> </div><blockquote class="gmail_quote" style="margin:0pt 0pt 0pt 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">Thanks Doug ------------------------------------------------------------------------------ Try before you buy = See our experts in action!
