Hi, Jim...<br>
<br>
Someone on the Rabbit team just pointed out to me that metronome currently doesn't work. We have a bug reported internally on it.<br>
<br>
Can you say a bit about what you're trying to do with it? Are you aiming to write a Rabbit plugin of your own and were planning to use metronome for guidance?<br>

That was helpful - I got farther - but not there yet.<br>
<br>
I did the checkout of the umbrella with the command above:<br>
<br>
hg clone <a href="http://hg.rabbitmq.com/rabbitmq-public-umbrella" target="_blank">http://hg.rabbitmq.com/rabbitmq-public-umbrella</a> -r bug23568<br>
<br>
but I did the 'make co' without any special parameters, so I assumed<br>
that it did hg commands with respect to the bug23568 branch.<br>
<br>
I built the metronome project as outlined on the Rabbit site and added<br>
the rabbit_metronome-0.0.0.ez and amqp_client.ez files to the<br>
rabbitmq-public-umbrella/rabbitmq-server/plugins directory, but when I<br>
start it up I get:<br>
<br>
linus:make run<br>

{"Kernel pid terminated",application_controller,"{application_start_failure,rabbit_metronome,{shutdown,{rabbit_metronome,start,[normal,[]]}}}"}<br>
<br>
Crash dump was written to: erl_crash.dump<br>
Kernel pid terminated (application_controller) ({application_start_failure,rabbit_metronome,{shutdown,{rabbit_metronome,start,[normal,[]]}}})<br>
<br>
And as advertised it creates a big honkin' dump file.<br>
<br>
I also had to create symbolic links so that the code would build. In my<br>
rabbitmq-public-umbrella/rabbit_metronome directory I created:<br>
<br>
amqp_client -> ../rabbitmq-erlang-client/dist/amqp_client<br>
rabbit_common -> ../rabbitmq-erlang-client/dist/rabbit_common<br>
<br>
The server works fine if run without adding plugins, but when I add them<br>
it bombs, so I know the plugins are the problem (Right?).<br>
<br>
I'm new to Erlang (interesting language), so all I did was cut and paste<br>
the example Erlang code, so if that code is out of date then it would be a problem.<br>
<br>
Also: I changed the port to 5679 so it would not interfere with the official<br>
installed RabbitMQ server on the same machine, and I set RABBITMQ_NODENAME<br>
to 'bunny'.<br>
<br>
Thanks,<br>
<br>

Nope. bug23274 has been abandoned. bug23568 replaces it, but is yet to<br>
go through QA. None of the documentation regarding writing plugins has<br>
been updated.<br>
<br>
> If not, what is the Mercurial command to get it?<br>
<br>
hg clone <a href="http://hg.rabbitmq.com/rabbitmq-public-umbrella" target="_blank">http://hg.rabbitmq.com/rabbitmq-public-umbrella</a> -r bug23568<br>
<br>
But you'll need to make sure all the plugins are also on branch bug23568<br>
for them to work with the new build system.<br>
<br>
If you're writing plugins from scratch, be sure to read the<br>
rabbitmq-public-umbrella/README.makefiles file, which has a helpful<br>
section on "Creating a new package".<br>
