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" : [
      "meta-key"
    ],
    "url" : "https://my-monitoring.example.com:1234/api/write",
    "jwt" : "blabla.blabla.blabla",
    "timeout": "5s",
    "idle_connection_timeout" : "5s",
    "flush_delay": "2s",
  }
}

• type: makes the sink an http sink
• meta_as_tags: Move specific meta information to the tags in the output (optional)
• url: The full URL of the endpoint
• jwt: JSON web tokens for authentication (Using the Bearer scheme)
• timeout: General timeout for the HTTP client (default '5s')
• max_retries: Maximum number of retries to connect to the http server
• idle_connection_timeout: Timeout for idle connections (default '120s'). Should be larger than the measurement interval to keep the connection open
• flush_delay: Batch all writes arriving in during this duration (default '1s', batching can be disabled by setting it to 0)
