Experts..
I have a query to find the property of the queue to check the in out statistics of message. It may be alias or any other queue, the statistics of the queue before and after firing the message has to be captured. So could anyone let me know the parameter which helps us in determining this.
Queue-->Qlocal/alias Queue/Remote Queue.
Thanks |

have your putting/sending and receiving/getting application capture and print the timestamp for you...

This is circular. Answering the question "why do you want to know this" with "because I want to know it" doesn't help. If you don't tell us your requirements, what you're trying to achieve, we're unable to offer alternatives if what you're actually asking isn't possible.

This isn't actually what you asked for in your original post. If you're trying to capture "in out statistics" as you originally stated (more formally called EnqCount & DeqCount) then performance events will capture these.
If you want the time stamp of the last message processed, then you'll need to build something. Having first determined if you mean the time stamp the message was processed or the time stamp of the message itself (which is the time it was put at the sender end, not picked up at the receiver). Note also that both alias and remote queues don't actually store messages themselves.
This goes back to elucidating your requirement as I said above.

Requirement:monitoring queues like whther message is landed on queue or not, If landed what is the time when message put to the queue and what is the time message processed from queue.
even I need same on alias/remote queues as well.
Suggetions. |

Sounds suspiciously like a COA/COD scenario to me...

in case you want to trace for one particular msg then you can hv a look at last message sent time of channel.... provided, sendinga nd receiving application are connecting to MQ using different channels...

This is a bad requirement. Your site is paying a lot of money for WMQ, and one of the reasons this has been done is because WMQ offers assured delivery. Hence you don't need to monitor if the message has landed on the queue, you need to monitor if WMQ is working properly. This is a standard requirement, is described in the Monitoring manual and has been discussed here a lot.

Do you actually want the time spent in transit of each individual message, or do you actually want the time messages spend sitting on a queue?
| bkRaju wrote: |

Why? What would this measure give you? Given that you're apparently monitoring the local queues?

Clarify your requirements and read some discussions.

With all the usual good reasons not to do it, and the problems COA/COD cause.

| I will give you a hint. Enable Queue Mon and Channel Mon in queue manager (V6.0 and above). This should help you in what ever you want to achieve. But yes this is not a correct way for monitoring bulk messages as advised in previous posts.. |

May be you can use some tool like Patrol.
May be you can write an exit considering all pros and cons of it.
And may be, you can modify the application putting/getting messages on a queue to record that time for you (an easier option).

amqsmon sample may help you. It will tell you how many PUTs and how many GETs occured on this queue during a specified interval(default: 1800 second). It will not provide the information for each and every individual msg.
thanks. |

The two statements have different treatment.
For the first one you need to setup either script or if you are using broker then some esql code to capture the time of in and out for all the messages, by capturing mqmd parameters and its value from the message.
For the second one, you should know when the application is done with putting the messages and its not going to put anymore.. because for active applications, they'll send the messages all the times and queue depth will grow (and would be picked up by some target appl. ) so how you'll come to know this message is the last message. It could be possible for batch interfaces, which fire a set of messages to the queue and then you can capture last message time.

Why dont to check the input and output count on the queue , just for the sake that messages are being put and received by applications at both the ends.
I am agree with all other posters that the requirement definition must be clear and specific., so that.. to the point suggestions can be given by without flogging the dead horse.
You can use "IS02: WebSphere Message Broker Explorer Plug-in" for mq explorer, to get the accounting n stats details at broker level., you'll get time stamp of message in/out (if by any chance you are using broker 6.1)
