# RabbitMQ Input Plugin
Reads metrics from RabbitMQ servers via the [Management Plugin](https://www.rabbitmq.com/management.html).
For additional details reference the [RabbitMQ Management HTTP Stats](https://cdn.rawgit.com/rabbitmq/rabbitmq-management/master/priv/www/doc/stats.html).
### Configuration:
```toml
[[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"]
## A list of exchanges to gather as the rabbitmq_exchange measurement. If not
## specified, metrics for all exchanges are gathered.
# exchanges = ["telegraf"]
```

### Tags:
- All measurements have the following tags:
- url
- rabbitmq_overview
- name
- rabbitmq_node
- node
- rabbitmq_queue
- url
- queue
- vhost
- node
- durable
- auto_delete
- rabbitmq_exchange
- url
- exchange
- type
- vhost
- internal
- 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)
```
