http_listener

HTTP listener service input plugin

The HTTP listener is a service input plugin that listens for messages sent via HTTP POST. The plugin expects messages in the InfluxDB line-protocol ONLY, other Telegraf input data formats are not supported. The intent of the plugin is to allow Telegraf to serve as a proxy/router for the /write endpoint of the InfluxDB HTTP API.

The /write endpoint supports the precision query parameter and can be set to one of ns, u, ms, s, m, h. All other parameters are ignored and defer to the output plugins configuration.

When chaining Telegraf instances using this plugin, CREATE DATABASE requests receive a 200 OK response with message body {"results":[]} but they are not relayed. The output configuration of the Telegraf instance which ultimately submits data to InfluxDB determines the destination database.

See: Telegraf Input Data Formats.

Example:

curl -i -XPOST 'http://localhost:8186/write' --data-binary 'cpu_load_short,host=server01,region=us-west value=0.64 1434055562000000000'

Configuration:

This is a sample configuration for the plugin.

# # Influx HTTP write listener
[[inputs.http_listener]]
  ## Address and port to host HTTP listener on
  service_address = ":8186"

  ## timeouts
  read_timeout = "10s"
  write_timeout = "10s"
