RabbitMQ Pulse

RabbitMQ Pulse is an experimental exchange plugin that publishes information made available by the rabbitmq-management plugin making cluster monitoring a push event instead of something you poll for.

Messages can be published in JSON format as they would be received from the management API or they can be published in a format that is compatible with Graphite's carbon AMQP client, providing conversionless integration into Graphite and systems like rocksteady.

This is a work in progress and is not meant for production systems (yet).


The x-pulse exchange type added by RabbitMQ Pulse creates a publishing exchange that will send status messages at pre-specified intervals to bound objects matching the routing key patterns it uses.

The rabbitmq-pulse plugin will publish cluster, node and queue statistics to a topic like exchange with varying routing keys to allow for stats at multiple layers of granularity. For example, to get all stats for a server with a hostname of megabunny, you could bind to .rabbit.megabunny. Or to get node stats for all hosts, you could do node.rabbit.. RabbitMQ Pulse uses a similar style of routing-key behavior as the topic exchange, but without the partial word matching (ie no node.rab.).

The messages are JSON serialized data with stats provided by the rabbitmq-management plugin.


  • Add the ability to bind to get stats for:
    • Queues
    • Connections
    • Channels
  • Handle shutdown cleanly
  • Handle add_binding/remove_binding, create, delete properly

Message Types

  • cluster overview: High-level cluster overview data
  • node stats: Per-node messages
  • queue stats: Per-queue messages


Currently, the best way to install the plugin is to follow the instructions at and setup the rabbitmq-public-umbrella checkout, clone the rabbitmq-pulse directory into it and custom compile the plugin.

Plugin Configuration

Default configuration values:

  • default_username: guest
  • default_interval: 5000

Interval is the number of miliseconds between publishing stats. To change the default configuration values, add a rabbitmq_pulse stanza in the rabbitmq.config file for the value you would like to override:

[{rabbitmq_pulse, [{default_username, <<"guest">>},
                   {default_interval, 5000},
                   {default_format, <<"json">>]}]

To override the default values, specify a username and/or interval as arguments when delcaring a x-pulse exchange.

Per-exchange optional configuration values

  • username: Username to connect to the vhost as
  • interval: Number of milliseconds between publishing of stats
  • format: The publishing format. Acceptable values are json or graphite.
