<div>All,</div>
<div> </div>
<div> I have various services which provide pasive results to Nagios. I want to know or assume that any service which has not checked in in over 30 minutes is tardy and crticical. I tried making it use "check_dummy 3 warning ncnet dead" with the check_freshness_ option and I can't seem to get dummy to generate any critical alerts.
</div>

<div>Can someone please provide an example of a working setup that will achieve what I'm looking for?</div>

<div>Thanks!</div>
