Is it possible to determine the average and/or peak message rate for a queue manager as a whole (including both client and bindings mode applications)? WMQ 7 on AIX. |

Am not sure if you are looking for the online and/or statistics monitoring on the queue manager !

I suspect he's looking for a simplified way of aggregating the statistics of the qmgr, without having to accumulate and sum them.
I don't know that there is a simple way. |

So I would have to enable stats on all the queues and then add them up?
Anyone written a nice script to do this? |

In this case, when I said "I don't know", I meant "i haven't checked the documentation to be sure"...
So it might be easier than enabling stats on everything and then collecting and aggregating...
but on the other hand, I figured you would have checked that first...  |

I have wanted, for some time, to craft a custom report in QPasa that would do that very thing.
But then, I'd like a unicorn as a pet and that is unlikely happen, either. <sigh> |

@zpat:
Out of curiosity, what is the motivation behind this request?  _________________ MQ & Broker admin |

mqtimes2 is the program provided by rfhutil ih03 (v7.0.1) for diff. platforms (including aix).
you can have a look at that, which reads the msgs from the queue and reports the msgs processed per second.
Document says.. Timeout is the maximum time in seconds to wait for a message. The program ends when the maximum number of messages is read or a time out occurs.

Yes, I have done that already.
The problem I now have is calcuating what percentage of the maximum rate, that we are currently using in production. i.e. what is the headroom? |

You will have a different rate for 10 byte messages vs. 10 Megabyte messages.
You will have a different rate for persistent messages vs. persistent messages.
You will have a different rate for NP messages depending on whether you have waiting getters at the time the putter puts.
If your environment processes a very predictable set of work as per the above variables (and maybe others) then you might be ok to use stats for the purpose you wish. If there is any significant variation in the above variables, then maybe the stats could mislead. |

I would first look at average and max rates for the SLA monitored channels/queues and check what else is happening when the SLA cannot be met...
This might give you an indication of where a bottleneck might be. It could be as simple as needing more logs / or a bigger log, or more buffer space etc...
It could also be that you need to scale some consumers...
As general rule, estimate correctly the traffic, estimate the log size, estimate correctly the different page set sizes, and give a decent buffer size (monitor the size) and you should not have much problems.
Remember also that on Zos some problem can arise from peripheral systems. If you have a CICS transaction consuming messages waiting on ressources from DB2, you are likely to blow your SLA... nothing to do with MQ though... OS/SYSPROG team can help you with prioritizing the resources...

If you are fortunate enough to have WMQ for z/OS, you an turn on SMF accounting and statistics capturing WMQ, DB/2, and related server address spaces. _________________ I like deadlines. I like to wave as they pass by.

no Z/OS unfortunately.
I am aware of the issue of message size (and the average size would be another useful metric).
It would be nice if MQ explorer could summarise all the stats for a given set of queues in a filter. |

The Acct&stats for MQExplorer supportPac should let you export a set of data as a CSV file for import into your favorite database or spreadsheet product for further analysis. |
