I am curious how others set up sampling intervals in their various monitoring products. I am thinking about how to balance the overhead of the sampling itself and the network traffic it creates against the currency of the sampled data.
Do you set different sampling intervals for development and production? Different intervals by object type, for example channels versus queues?
Or perhaps you set your intervals per specific MQ object, based upon the nature of the application using particular MQ objects? For example, a channel used for asynchronous batch processing might only be sampled every five minutes, but a channel used for real-time synchronous processing might get checked every 15 or 30 seconds?
I'll appreciate your thoughts on this topic. Thanks very much.

I would never, ever, ever under any circumstances configure the monitoring of a zOS queue manager at 15 second intervals... without a signed document from the CIO approving the CPU cost for running the command server.

Usually we sample our distributed QMGRs every 30 seconds and the MF ones every minute.

We use QPASA and the agents report once a minute across the board. Sometimes a minute can feel like forever when your waiting for the screen to refresh! But we found it a good balance between getting timely data and overloading our QPASA DB with data and our MQ command servers with requests.
