The following check returns a CRITICAL state, when the value is a negative number (in my case more messages were dequeued than enqueued) : command_line $USER1$/check_jmx4perl --url http://$HOSTADDRESS$:$_HOSTPORT$/j4p --name enqueued-on-myQueue --mbean jboss.messaging.destination:name=myQueue,service=Queue --attribute MessageCount --delta 60 --critical 30 --warning 5 --label "Increase of messages enqueued on myQueue: %v" I assume that this is not expected behavior. If it is not a bug, it would be great to know a possible workaround. Thanks!

The specification of the critical and warning threshold follows the
"Nagios Plugin Development Guidelines"
--> http://nagiosplug.sourceforge.net/developer-guidelines.html#THRESHOLDFORMAT

I.e. if you want to allow all rates between [-infinity,30], then you should specify " ~:30" as
threshold.

Or, for your use case above:

--warning "~:5" --critical "~:30"

hope this helps ...

Yes, it works, I didn't know the thresholds specification. Thanks for help and sorry for bugging you.
