<p class="MsoNormal">Hi - <o:p></o:p></p>
<p class="MsoNormal">I've got a little problem wih Xymon 4.3.12 xymond_alert dumping core when trying to use the SCRIPT keyword in alerts.cfg. We're trying to create a script that will contain some custom logic for whether to send alerts based on specific
processes or not: we have a situation where we need to disable process checking for one particular process on certain hosts at a certain time of day but want the other process checks to continue and can't find any way of doing this with the standard arguments
so we figured we'd have to pass along the checking to a custom script.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">However when I try to set up the alert, I get a coredump, and the script does not run. My alerts.cfg statement is:<o:p></o:p></p>
<p class="MsoNormal">HOST=%^rqstp.* SERVICE=procs<o:p></o:p></p>
<p class="MsoNormal"> SCRIPT /home/bb/RQTimedProcAlerts.sh rqit@readq.com DURATION>1m REPEAT=10 RECOVERED COLOR=red TIME=W:0801:1830
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I have also tried to eliminate some of those other keywords and gone to the simple:<o:p></o:p></p>
<p class="MsoNormal"> SCRIPT /home/bb/RQTimedProcAlerts.sh rqit@readq.com COLOR=red<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">But I still experience the coredump. Here is a backtrace:<o:p></o:p></p>
