Hi,
I have some doubts about the tools and environment in general and would
someone clear them for me please ?
1. What is the rate of stats displayed by qpid-queue-stat. I'm confused
by the fact that it displays "Sec" as 10. So are the stats at 10 sec rate or
1 sec rate but measured only every 10 secs?
qpid-queue-stat displays the statistics as they are published by the
broker. By default, this is every 10 seconds. You can change the rate
using the --mgmt-pub-interval switch on the broker's command line. The
rates displayed by qpid-queue-stats are normalized to units-per-second.
2. How do i clear the exchange, server and client queue stats before
re-running stats - currently i have to bring everything down to get fresh
stats - this seems extremely cumbersome.
There's no support for clearing the stats but qpid-queue-stats only
shows rates and depths which should go to zero by themselves between tests.
3. Does C++ clients support a management queue like cpp broker, to get
stats etc?
No.
4. I create queues with the same name everytime. When i bring down my
cleitn and reconnect again i seem to get the data from the old queue though
i have not mentioned persistence as an attribute of my queue. What gives?
You should add "auto_delete=True" to the session.queue_declare
function. Otherwise, the queue stays in place between test runs.
connection.start()
session = connection.session(str(uuid4()))
server_q_name = "pyclient-feeds-queue"
session.queue_declare(queue=server_q_name, exclusive=True)
local_q_name = "local feeds queue"
local_q = session.incoming(local_q_name)
session.message_subscribe(queue=server_q_name, destination=local_q_name)
local_q.start()
Thanks
