http sink

The http sink uses POST requests to a HTTP server to submit the metrics in the InfluxDB line-protocol format. It uses JSON web tokens for authentification. The sink creates batches of metrics before sending, to reduce the HTTP traffic.

Configuration structure

{
  "<name>": {
    "type": "http",
    "meta_as_tags" : true,
    "url" : "https://my-monitoring.example.com:1234/api/write",
    "jwt" : "blabla.blabla.blabla",
    "timeout": "5s",
    "max_idle_connections" : 10,
    "idle_connection_timeout" : "5s",
    "flush_delay": "2s",
  }
}
  • type: makes the sink an http sink
  • meta_as_tags: print all meta information as tags in the output (optional)
  • url: The full URL of the endpoint
  • jwt: JSON web tokens for authentification (Using the Bearer scheme)
  • timeout: General timeout for the HTTP client (default '5s')
  • max_idle_connections: Maximally idle connections (default 10)
  • idle_connection_timeout: Timeout for idle connections (default '5s')
  • flush_delay: Batch all writes arriving in during this duration (default '1s', batching can be disabled by setting it to 0)
