## `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
|
|
|
|
```json
|
|
{
|
|
"<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)
