[zeromq-dev] Is there a way to query ZeroMQ statistics

[Martin.Belanger at dell.com]

Hi,

I'm trying to fine tune my PUB-SUB system. I've set the high water mark (RCVHWM/SNDHWM) to zero (no-limit) and now I would like to see how high the "water" actually gets after running the system for a while. 

Using zmq_getsockopt() with ZMQ_RCVHWM/ZMQ_SNDHWM only retrieves the high water marks that were previously set with zmq_setsockopt() (i.e. 0), but not the actual level that was reached.

Is there a way to query the actual "water level" that was reached?

Thanks,
Martin
