RabbitMQ Variable Shovel

RabbitMQ vShovel is a WAN-friendly tool for moving messages from a queue residing on an AMQP source broker, to a remote endpoint of any desired type, such as an HTTP endpoint.

Each endpoint is an implementation of the rabbit_vshovel_endpoint behaviour. The following message shovelling operations and protocol endpoints are currently supported, with more to be introduced as the plugin further grows:

• AMQP 0.9.1 (RabbitMQ) to an AMQP 0.9.1 endpoint.
• AMQP 0.9.1 to an HTTP 1.1 endpoint.

Supported RabbitMQ Versions

This plugin is compatible with RabbitMQ 3.5.x and 3.6.x.

                           ]}]}]},
              {destinations,
                  [{protocol,  http},
                   {address,   "https://56.12.331.123/server"},
                   {arguments, [{keepalive, 10},
                   {method,    post},
                   {ssl,       []}]}]},
              {queue,               <<>>},
              {prefetch_count,      10},
              {ack_mode,            on_confirm},
              {publish_properties,  [{delivery_mode, 2}]},
              {add_forward_headers, true},
              {publish_fields,      [{exchange,   <<"my_direct">>},
                                     {routing_key, <<"from_shovel">>}]},
              {reconnect_delay,     5}]}
          ]}
]}].

3. Verification

Once configured, verify status of the shovel using the following command (on a Unix-like OS):

rabbitmqctl eval 'rabbit_vshovel_status:status().'

and on Windows;

rabbitmqctl eval "rabbit_vshovel_status:status()."
