Hi All,
We were recently trying to capture MQ Statistics on the zOS platform to bring it in line with what we have on the distributed systems at our middleware estate.
However I see that on the zOS qmgr - the MQ Statistics Monitoring is only available for the Channel and not at the queue level.
I tried to check this at the queue level too. We only have the Monitoring and Accounting feature available but not Statistics (distributed has all 3).
IBM documentation on the subject also state the same - what I found above.
Is this feature supported only on the distributed platforms then?
If so, is there a way to achieve this on the mainframe zOS?
We use the MQ statistics published by the qmgr to derive some useful history as to how many messages passed through a queue at any given point.
Thanks much |

Thanks
yes I have seen the SMF records and they present a pureplay mainframe view of the MQ performance stats that can be views on the host.
i was hoping to find something that works like on distributed (with stats published as messages on SYSTEM queues) which can then be fed into inhouse tools to present a single view of the stats throughout the middleware estate.
Looks like thats not supported! |

Hi Aravind,
Thanks for bringing this up ? I?ve been wondering about the exact same thing!
I?m still learning my way around MQ on z/OS, but from everything I?ve seen so far, it does seem like IBM has structured the monitoring features quite differently between platforms. On distributed, having all three ? Monitoring, Accounting, and Statistics ? makes it much easier to pull specific data points like queue-level throughput, which I find super useful for historical tracking and capacity planning.
But yeah, on z/OS, I?ve only ever been able to access Accounting and Monitoring data as well. Like you said, Statistics seem to be reserved mostly for channels. I?m guessing it might have to do with performance overhead on the mainframe?
I?d love to hear if anyone has found a workaround ? maybe by using SMF records or even leveraging Accounting class 3 data to simulate queue stats over time? I?m still trying to wrap my head around how feasible that would be without adding too much overhead.
Really curious what others have done to close the gap between distributed and z/OS in terms of queue-level visibility.  |
