Hi, Thanks all. The following works best: define service { .... check_freshness 1 freshness_threshold 300 check_command check_dummy } define command{ command_name check_dummy command_line $USER1$/check_dummy 2 "Stale data: The server has not responded." } <div class="gmail_quote">On Fri, Jan 8, 2010 at 4:30 PM, Getchell, Kristoffer M <<a href="mailto:K.Getchell@kingston.ac.uk">K.Getchell@kingston.ac.uk</a>> wrote: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> <div class="im">Hi Could you enable freshness checking and set the check command to something that sets the status to critical (for example you could write an external command into the external command queue)? So long as passive results were received within the freshness threshold, the check command won't be executed, so the status you see will be what is reported by the passive check result. If no passive check results are received you will then be notified of a critical situation as the freshness check command would then be executed and return a critical alert. To this end, I would redefine your passive service command as follows: </div><div class="im">define service { use passive_service service_description HW Sensors hostgroup_name hgp_webservers, hgp_db, hgp_search, hgp_image check_command check_dummy active_checks_enabled 0 passive_checks_enabled 1 </div> check_freshness 1 <div class="im"> freshness_threshold 300 check_command issue_critical_alert ; this command is run only if the service results are "stale" } Kind regards, Kris </div><div class="im">From: Pankaj [mailto:<a href="mailto:penguinhead@gmail.com">penguinhead@gmail.com</a>] Sent: 08 January 2010 07:30 To: Nagios Mailinglist Subject: [Nagios-users] non sticky passive checks </div><div><div></div><div class="h5">Hi, I've configured passive service checks and am reporting back the results using nsca.
