    Hi Surbhi,

    You might find this blog post (Graphing queue get/put rates) that I wrote for another purpose (comparing graphing in our tools) useful, as it starts by comparing the two main mechanisms for obtaining what you want, messages in and messages out.

    You can ignore mention of the tools and scroll down to the heading "Which should I use?" for the details to help you.

    Any questions beyond what is in that post, please ask them here. 

    Cheers,
    Morag

    Your site likely has enterprise monitoring tools deployed across the environment. One or more of those tools likely has officially support for Monitoring and Alerting for IBM MQ. I would start there. The bosses will smile warmly if you choose the enterprise's monitoring solution versus rolling your own.

    Richard Nikula said in another thread:

    "I have heard IBM say that activating queue monitoring is actually negative overhead.  That is, they actually have to do work to not report it.  It is always collected for internal MQ usage.   That is consistent with our experience.   When we were recently doing our performance benchmarking for different messages services (see     https://www.nastel.com/performance-benchmarking-april-2022/), we did testing with and without queue monitoring enabled and it made no significant difference in the results.  We recommend all customers run with it on as the added statistics are very valuable in almost every situation.  As noted for queues, all selections including High are the same."

    Hi Surbi,

    There are various third party tools available that can help you with this. Unsurprisingly I would recommend the one from my company. We have a recent blog post here - What is IBM MQ Monitoring?
