This is a backend for the Lager Erlang logging framework.

https://github.com/basho/lager

It will send all of your logging messages to the exchange you specify and use the logging level as the routing key. It uses a smart connection pool to your broker. If the connection drops or becomes unusable, the backend will reconnect.

Include this backend into your project using rebar:

{lager_amqp_backend, ".*", {git, "https://github.com/jbrisbin/lager_amqp_backend.git", "master"}}

You can pass the backend the following configuration (shown are the defaults):

{lager, [
  {handlers, [
    {lager_amqp_backend, [
      {name,        "lager_amqp_backend"},
      {level,       debug},
      {exchange,    <<"lager_amqp_backend">>},
      {amqp_user,   <<"guest">>},
      {amqp_pass,   <<"guest">>},
      {amqp_vhost,  <<"/">>},
      {amqp_host,   "localhost"},
      {amqp_port,   5672}
    ]}

Apache 2.0, just like everything else I do. :)
