AMQP Output Plugin

This plugin writes to a AMQP 0-9-1 Exchange, a prominent implementation of this protocol being RabbitMQ.

This plugin does not bind the exchange to a queue.

For an introduction to AMQP see:

• amqp: concepts
• rabbitmq: getting started

Global configuration options

In addition to the plugin-specific configuration settings, plugins support additional global and plugin configuration settings. These settings are used to modify metrics, tags, and field or create aliases and configure ordering, etc. See the CONFIGURATION.md for more details.

Configuration

# Publishes metrics to an AMQP broker
[[outputs.amqp]]
  ## Broker to publish to.
  ##   deprecated in 1.7; use the brokers option
  # url = "amqp://localhost:5672/influxdb"

  ## Brokers to publish to.  If multiple brokers are specified a random broker
  ## will be selected anytime a connection is established.  This can be
  ## helpful for load balancing when not using a dedicated load balancer.
  brokers = ["amqp://localhost:5672/influxdb"]

  ## Maximum messages to send over a connection.  Once this is reached, the
  ## connection is closed and a new connection is made.  This can be helpful for
  ## load balancing when not using a dedicated load balancer.
  # max_messages = 0

  ## Exchange to declare and publish to.
  exchange = "telegraf"

  ## Exchange type; common types are "direct", "fanout", "topic", "header", "x-consistent-hash".
  # exchange_type = "topic"

  ## If true, exchange will be passively declared.
  # exchange_passive = false

  ## Exchange durability can be either "transient" or "durable".
  # exchange_durability = "durable"

  ## Additional exchange arguments.
  # exchange_arguments = { }
  # exchange_arguments = {"hash_property" = "timestamp"}

  ## Authentication credentials for the PLAIN auth_method.
  # username = ""
  # password = ""

  ## Auth method. PLAIN and EXTERNAL are supported
  ## Using EXTERNAL requires enabling the rabbitmq_auth_mechanism_ssl plugin as
  ## described here: https://www.rabbitmq.com/plugins.html
  # auth_method = "PLAIN"

  ## Metric tag to use as a routing key.
  ##   ie, if this tag exists, its value will be used as the routing key
  # routing_tag = "host"

  ## Static routing key.  Used when no routing_tag is set or as a fallback
  ## when the tag specified in routing tag is not found.
  # routing_key = ""
  # routing_key = "telegraf"

  ## Delivery Mode controls if a published message is persistent.
  ##   One of "transient" or "persistent".
  # delivery_mode = "transient"

  ## InfluxDB database added as a message header.
  ##   deprecated in 1.7; use the headers option
  # database = "telegraf"

  ## InfluxDB retention policy added as a message header
  ##   deprecated in 1.7; use the headers option
  # retention_policy = "default"

  ## Static headers added to each published message.
  # headers = { }
  # headers = {"database" = "telegraf", "retention_policy" = "default"}

  ## Connection timeout.  If not provided, will default to 5s.  0s means no
  ## timeout (not recommended).
  # timeout = "5s"

  ## 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 Proxy Configuration
  # use_proxy = false
  # proxy_url = "localhost:8888"

  ## If true use batch serialization format instead of line based delimiting.
  ## Only applies to data formats which are not line based such as JSON.
  ## Recommended to set to true.
  # use_batch_format = false

  ## Content encoding for message payloads, can be set to "gzip" to or
  ## "identity" to apply no encoding.
  ##
  ## Please note that when use_batch_format = false each amqp message contains only
  ## a single metric, it is recommended to use compression with batch format
  ## for best results.
  # content_encoding = "identity"

  ## Data format to output.
  ## Each data format has its own unique set of configuration options, read
  ## more about them here:
  ## https://github.com/influxdata/telegraf/blob/master/docs/DATA_FORMATS_OUTPUT.md
  # data_format = "influx"

Routing

If routing_tag is set, and the tag is defined on the metric, the value of the tag is used as the routing key. Otherwise the value of routing_key is used directly. If both are unset the empty string is used.

Exchange types that do not use a routing key, direct and header, always use the empty string as the routing key.

Metrics are published in batches based on the final routing key.

Proxy

If you want to use a proxy, you need to set use_proxy = true. This will use the system's proxy settings to determine the proxy URL. If you need to specify a proxy URL manually, you can do so by using proxy_url, overriding the system settings.
