RabbitMQ Input Plugin

Reads metrics from RabbitMQ servers via the Management Plugin.

For additional details reference the RabbitMQ Management HTTP Stats.

Configuration:

[[inputs.rabbitmq]]
  ## Management Plugin url. (default: http://localhost:15672)
  # url = "http://localhost:15672"
  ## Tag added to rabbitmq_overview series; deprecated: use tags
  # name = "rmq-server-1"
  ## Credentials
  # username = "guest"
  # password = "guest"

  ## Optional SSL Config
  # ssl_ca = "/etc/telegraf/ca.pem"
  # ssl_cert = "/etc/telegraf/cert.pem"
  # ssl_key = "/etc/telegraf/key.pem"
  ## Use SSL but skip chain & host verification
  # insecure_skip_verify = false

  ## Optional request timeouts
  ##
  ## ResponseHeaderTimeout, if non-zero, specifies the amount of time to wait
  ## for a server's response headers after fully writing the request.
  # header_timeout = "3s"
  ##
  ## client_timeout specifies a time limit for requests made by this client.
  ## Includes connection time, any redirects, and reading the response body.
  # client_timeout = "4s"

  ## A list of nodes to gather as the rabbitmq_node measurement. If not
  ## specified, metrics for all nodes are gathered.
  # nodes = ["rabbit@node1", "rabbit@node2"]

  ## A list of queues to gather as the rabbitmq_queue measurement. If not
  ## specified, metrics for all queues are gathered.
  # queues = ["telegraf"]

Tags:

• All measurements have the following tags:

  • url

• rabbitmq_overview

  • name

• rabbitmq_node

  • node

• rabbitmq_queue

  • url
  • queue
  • vhost
  • node
  • durable
  • auto_delete

Sample Queries:

Message rates for the entire node can be calculated from total message counts. For instance, to get the rate of messages published per minute, use this query:

SELECT NON_NEGATIVE_DERIVATIVE(LAST("messages_published"), 1m) AS messages_published_rate
FROM rabbitmq_overview WHERE time > now() - 10m GROUP BY time(1m)

Example Output:
