## Configuration

```toml @sample.conf
# Reads metrics from RabbitMQ servers via the Management Plugin
[[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 TLS Config
  # tls_ca = "/etc/telegraf/ca.pem"
  # tls_cert = "/etc/telegraf/cert.pem"
  # tls_key = "/etc/telegraf/key.pem"
  ## Use TLS 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.
  ## Deprecated in 1.6: Use queue_name_include instead.
  # queues = ["telegraf"]

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

  ## Metrics to include and exclude. Globs accepted.
  ## Note that an empty array for both will include all metrics
  ## Currently the following metrics are supported: "exchange", "federation", "node", "overview", "queue"
  # metric_include = []
  # metric_exclude = []

  ## Queues to include and exclude. Globs accepted.
  ## Note that an empty array for both will include all queues
  # queue_name_include = []
  # queue_name_exclude = []

  ## Federation upstreams to include and exclude specified as an array of glob
  ## pattern strings.  Federation links can also be limited by the queue and
  ## exchange filters.
  # federation_upstream_include = []
  # federation_upstream_exclude = []
```

## 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:

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