Hi all,
I'll try to be as brief and descriptive as possible.
Setup:
I have a system that e.g. does the following:
sourceQ --> intermediateQ --> destinationQ.
I put a message on the sQ, it goes onto the iQ, then lastly it gets put on the dQ.
Task:
I want to create a small model to assess performance by checking the put times of each message to see how long it takes from one checkpoint (Q) to another.
I've done this so far by checking the avg. intervals between the put times but this proves to be a bit slower due to the queueing theory.
Checking Logs:
So what I want to do now is to potentially check the logs in /var/mqm/log/qMgr/active/*.
If I send 200 messages through, is there an easy way to say using trace, or dmpmqlog to pipe the contents of a unique identifier (for only PUT DATE/TIME) into a file and have a look at them this way?
I've assessed the requirements and our circular logging of 3x16mb should be more than enough for the 200x180kb messages (incl. overheads of the logging).
I know ideally I should look into better monitoring/performance solutions, but currently we do not have a budget to do so...
Any constructive help would be greatly appreciated! |

No you don't. The logs are not intended to be read by anything other than the queue manager.

No easy way no.

If you say so, though I don't see the connection to your other questions.

I was going to suggest writing an exit.. but why do that when a support pac is available

Without any support packs or other means, here is a quick self help...
Make sure the qmgrs will record the msgage  check the manuals on how to do that 
Run some mqsc type script at fixed intervals (every 5 mins?) against the corresponding local and xmit queues. Check why you would see either queue depth or message age...
Most of the delays are (in my experience) caused by an application (scaling, design etc...). However you have the odd one out where you need a PMR to get a fix... or a network admin for some help... So make sure you checked your turf first. (any FDC's?).
You can also use the MQroute check app (see the manuals) for each leg to determine if there is a network slow down...
Have fun
