Does WMQ fire event(s) when message is 'put' or 'get' onto/from a queue? If so, how can I capture them? Target OS is Windows 2003.

I'm thinking about either writing some sort of windows service, which will watch WMQ events and respond to them, use some soft of monitoring tool's API (preferably free), or use something that's already build into WMQ 6.0.

Basically what we want to do is to route messages from one queue (in) to another one (out). The problem is that these messages need to interface with another application, which uses interval based adapters (every so on it will go and check the queue for messages). Let's say that polling is every 5 min. then what happes is that once the adapter is fired it pulls messages in bigger chunks that it is capable of processing, so we lower the batch size. But this really doesn't solve our problem. We don't want the application to sit idle for 5 min. and then be flooded with number of messages that it can't manage. We would much rather see it work for 5 min. at its peak efficency.

What we would really like to have is some sort of throtling junction, which would monitor queues for put/get events, automatically pull messages off queues and forward them to an application, which has event-centric adapter. Obviously this is the same application but unfortunately it does not have an adapter that's event based.
