Hi All
I'd like to set special monitoring for a queue.
If any message is not processed within certain amount of time (like 5mins)
, i.e, if there is no mqget activity against the queue we would like to be notified.
How can this be done? any hints, tips, docs, links appreciated.
Using mq 6.0.2.4 in unix
thx |

Look up "queue service interval events" in the WMQ documentation.

If you've got influence over the message being sent, you could also use report messages

I dont have influence over the message being sent as these are spesific applications using queues.
searched for this option; "queue service interval events"
I dont think this will help either as this also generates events when you put messages on the queue with like mqput.
I am looking only for some type of event generated when any message not consumed from the queue, i.e, no mqget against a queue for like 5 mins. In another words, no activity to process(consume) messages in the queue.

I never said it would be as simple as just picking up a message. You might have to do some work, like determining if the event is one of the ones that you're interested in.

What you're describing is the queue service interval high event, which as you correctly point out is produced in association with other events. If you don't think that will help you then you're down to writing custom monitoring code.
Which experience teaches is less efficient & more troublesome than the events. But you know your needs best. You wanted a hint, that was mine & based solely on what I've done in the past when I've had a requirement similar to yours.

You could also look at the options available for monitoring the LastPutTime on the queue.
I forget if there's a specific event message or statistics message for that. |

ok, I looked more in detail to "queue service interval events"
I made the test setup
ALTER QMGR PERFMEV(ENABLED)
ALTER QLOCAL(<qname>) QSVCINT(10000) QSVCIEV(HIGH)
How do I read for these events from "SYSTEM.ADMIN.PERFM.EVENT"
MQRC_Q_SERVICE_INTERVAL_HIGH
MQRC_Q_SERVICE_INTERVAL_OK
do I need coding to read these?
I only have some perl and I haven't done any mq coding.
thx |

The perl modules for MQ in CPAN have a lot of helpers in this area... |

You might also want to look into specific monitoring software.
You can monitor the time on queue and get rate and alert on that.
You will need to check the product specification. We do alert on that and we use QPasa.... (in the process of upgrading to the latest version called BMC Middleware and Performance Monitoring or something like that).
Have fun

You can also use MQ APIs to get the age of oldest message on the queue (MSGAGE).
Based on the oldest message present on the queue you can have alerts. |
