# AMQP Output Plugin
|
|
|
|
This plugin writes to a AMQP 0-9-1 Exchange, a prominent implementation of this protocol being [RabbitMQ](https://www.rabbitmq.com/).
|
|
|
|
This plugin does not bind the exchange to a queue.
|
|
|
|
For an introduction to AMQP see:
|
|
- https://www.rabbitmq.com/tutorials/amqp-concepts.html
|
|
- https://www.rabbitmq.com/getstarted.html
|
|
|
|
### Configuration:
|
|
```toml
|
|
# 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
|
|
|
|
## 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.
