Looking at 6.0 as I have no experience yet with 6.1 the only thing you can get from the admin perspective is the number of "additional" instances deployed to the broker. If you want to see if any additional instance is being used by the broker you need to look at the input queue status and check for the number of instances with the name DataFlow that have the queue open for input.

The CMP with the use of it's APIs can give you the number of additional flow instances deployed. MS0B inquiring on the input queue should be able to give you the number of instances actually used by the broker (this is dynamic depending on broker resource availability). To make sure that the number of instances is adequate make sure there is no queue depth on the input queue. (avg time of the message on the input queue should be counted in ms).

Remember it really all depends on your SLA. If your SLA is 24 hours it may well be adequate to only have one instance of the flow and let the input queue even out the load.

Have fun
