Sure, there is also a high level API in python for doing that.

Carl, Thanks for the reply.
Is there any way i can subscribe for these stats and aggregate them in a
normal python client, rather than learning qmf? I was under the impression
that the broker was publishing these stats?
Or can i talk QMF using python?
Thanks

Hi,
I 'm trying to setup a performance load testing framework for evaluating
the
subscription performance and I need to measure the load rates.
The reason i need this is that i'm trying to bombard my broker from
multiple
sources and i need to measure the single effective rate of incoming
messages
at the broker end.
The qpid-queue-stats tools gives me the enque rate, but i cannot use this
because i'm not trying to enqueu everything i recieve onto other
subscribers
due to infrastructure bottle-necks. (maybe later but not right now).
Is there any way i can get this rate from the broker? What other stats are
available from the broker?
Thanks

There are a tone of stats, I am note sure there is a broker wide load
number however, that would need to be aggregated
I would think. All the rate info for each connection or queue can be
retrieved via QMF and then it can aggregated.
Best would be to use qpid-tool to find the stat to aggregate and then write
a QMF client to pull those stats, connection can
give you in bytes.

An easier way would be to use the data off the exchanges, as their are less
of them to aggregate.
