That is correct. If you bind a queue to that exchange, you can receive
management updates. If they're simply dropped, there's no buildup of
resources.

Rob/Steve,
Thank you for your reply, i assume it wont hold any resources and it wont
cause any performance issues.

As Steve mentioned, the exchanges don't queue messages, they only
route them (to queues). That is, there are no messages 'in' the
exchange, as they dont hold messages.
Those numbers are simple counts of what has occurred during operation.
The broker keeps those records and then supplied them to qpid-stat
when it queried for the information.

I am confused now, in previous email you said "They are not held in
memory". When qpid-stat says there are messages in that exchange those
messages should be some where right either in memory or in FS or
qpid-stat
is displaying false output? so dropped messages will be gone and they
wont
be in memory or in FS? if that is the case how qpid-stat knows about that
message count?
Thanks,

Thank you Steve, do you know what are those exchanges for? when it say
drop those messages are still in file system so will file system grows
as those
msg count grow?

The message counts you see for qpid.management are "drops" - they
were
not routed to a queue (no topic matches on any of its bindings).
They
are not held in memory. Exchanges route messages, they do not queue
them.
So there's no resource issue with those numbers.

One more thing to add, does it impact qpid performance?

Hi,
Do you know what are these messages in these exchanges and why
they didn't get consumed and will it cause any issue if those
msg
number grow if so how to resolve that issue? restarting qpidd
may
clear those messages but wanted to know if we can configure to
set
threshold and
clear them automatically.
