Roughly, the RabbitMQ metronome plugin in Elixir.
The tricky bit of getting an Elixir plugin to work is that you need to build .ez archives of all the dependencies, including Elixir. Metronomex builds archives for dependencies, while building one for Elixir is a bit more involved.
Just run make ez and various dirty tricks will be executed to create the needed archives.
Checkout the Elixir source code. MAKE 100% SURE YOU HAVE THE SAME OTP VERSION AS YOUR TARGET RABBITMQ INSTALLATION! (or, at least, not a newer one :-)).
git clone git@github.com:elixir-lang/elixir
cd elixir
make
cd lib
ln -s elixir elixir-1.8.1
zip -r elixir-1.8.1.ez elixir-1.8.1/ebin
rm elixir-1.8.1
Put the resulting .ez file in your RabbitMQ directory and you're done. On Linux:
sudo cp elixir-1.8.1.ez /usr/lib/rabbitmq/plugins
I haven't tried Logger yet - don't include it in :extra_applications and don't use it.
Declare rabbit and rabbit_common as dependencies (see mix.exs) so that your
application won't be started until the RabbitMQ server is started.
