Good day,

I just installed rabbitmq 2.1.1 via .deb package on Ubuntu 10.10 and
got the .ez files for the jsonrpc-channel and management plugins. When
I visit http://localhost:55672/ I see Management Console, HTTP API,
Command Line Tool entries. However - there is no entry for
jsonrpc-channel (for the examples). I've managed to get it running
with rabbitmq 1.7, but no luck with 2.1.1. Attaching the logs.

Regards,
Emil

Hi Emil. The .ez file for jsonrpc-channel does not install the examples,
since there would be no obvious way to remove them for production use.
And the rpc and js_root contexts don't appear in the list since there's
no point directly clicking on them.

Unfortunately this does mean it's not exactly obvious that anything is
happening! If you go into the management plugin overview page and expand
"Applications" you should find rabbit_jsonrpc, rabbit_jsonrpc_channel
and rfc4627_jsonrpc applications running.

I'll have a think about how we can make this clearer.

Cheers, Simon

Hi

beam.smp is taking ebtween 70% - 90% of my CPU and around 780M RES and 980
VIRT.

I'm running rabbitmq-server 1.8.1
and Erlang R14A (erts-5.8) [source] [64-bit] [smp:2:2] [rq:2]
[async-threads:0] [hipe] [kernel-poll:false]

Any ideas please?

Thank you in advance
Mutaz

It *is* a problem though when the groups are formed dynamically on
a per message basis, i.e. when each consumer has a unique secret
token, known to the producer, and the producer constructs the
recipient group of the message on the fly by including all the
intended recipient's tokens in the message headers.
I understand you now, and above is exactly the situation I have. I
wonder if a custom exchange type can remove headers from a message
prior to delivery.
Here is a design:

Allow CC and BCC fields* when publishing. These are given to exchange
types** when routing (i.e., they are part of the envelope); and, the
routing code removes Bcc before actually delivering to queues.

Full semantics left as an exercise*** for the reader.

* They would probably have to be put in message headers, but possibly
they could be given specific support in our clients.

** We'd update direct and topic to take account of them; fanout and
headers don't need to, and other types given be given the fields and do
what they like.

*** For example, "" is a valid routing key, so how do you send to
multiple recipients just with BCC field?


Michael

    Rabbit certainly shouldn't be consuming 70-90% of the CPU when handling
    just a few messages an hour.

    What do 'rabbitmqctl list_queues' and 'rabbitmqctl list_connections' show?

    Also, 1.8.1 is quite old. Please upgrade to the latest version. While I
    don't recall any bug fixes in relation to the problem you are
    describing, it will be much easier to identify the cause if you can
    reproduce the behaviour in the current rabbit release.

    Regards,

    Matthias.
