MQSeries.net :: View topic - Message flow Transaction time calculation

Hello everybody,

We are supporting performance testing of message flows running on wmb 8. The tool we are using is Enterprise Test Robot. This tool was awesome until Friday as the only requirement we had from client was to capture the server capacity in terms of transactions per sec (tps) meaning capture the tps count when server hits 90% utilization.

Now client came up with a valid question "what was the transaction interval (duration of picking the message from queue + transform the message + put message to destination queue) when the CPU utilization was 90%?" I say this valid because the server may be processing an expected number of transactions but if its taking too much time to respond, the purpose is still defeated. Our SLAs are in milliseconds. So transaction time is indeed crucial.

I tried the Flow statistics through MB Explorer but wasn't useful as it overwrites data and doesn't capture transaction interval. So we are trying to establish a method to capture the transaction interval but are indeed running out of ideas. We can't use any other tools as client is not willing to purchase license.

Please suggest how best this might be accomplished. Thanks in advance.
