Subject: Re: Generating mon trap for use as heartbeat

David,
That would be great if you try it and post the results.
Also, thanks to Ed for the montrap script and Kastus for pointing out
the mon.monitor. I did not see the mon.monitor and it looks like it
would detect some problems that the heartbeat does not.
Cheers,
Michael Vogt
The script I wrote is attached. The config blocks on my servers look like
this:
One the server where I want to generate the trap:
watch mon-services-slave
service mon-heartbeat-generator
description Generate Mon Traps to a remote Mon system, to prove
that this Mon system is queuing processes interval 1m
monitor mon-trap.monitor --group mon-services-slave --service
mon-heartbeat-trap hostname-of-destination-server-here ;;
On the server where I want to receive the trap and timeout if I stop
receiving traps:
watch mon-services-slave
service mon-heartbeat-trap
description Receive Mon Traps from a remote Mon system, to verify
the remote system is queuing processes traptimeout 5m
period Mail_Log: wd{1-7}
alert mail.alert logging-address-here
upalert mail.alert logging-address-here
alertafter 2
alertevery 6h
<other period definitions, insert your own as heeded>
So far it seems to be working as expected.
