## `http` receiver
The `http` receiver can be used receive metrics through HTTP POST requests.
### Configuration structure
```json
{
"<name>": {
"type": "http",
"address" : "",
"port" : "8080",
"path" : "/write",
"idle_timeout": "120s",
"username": "myUser",
"password": "myPW"
}
}
```
- `type`: makes the receiver a `http` receiver
- `address`: Listen address
- `port`: Listen port
- `path`: URL path for the write endpoint
- `idle_timeout`: Maximum amount of time to wait for the next request when keep-alives are enabled should be larger than the measurement interval to keep the connection open
- `keep_alives_enabled`: Controls whether HTTP keep-alives are enabled. By default, keep-alives are enabled.
- `username`: username for basic authentication
- `password`: password for basic authentication
The HTTP endpoint listens to `http://<address>:<port>/<path>`
### Debugging
- Install [curl](https://curl.se/)
- Use curl to send message to `http` receiver
```bash
curl http://localhost:8080/write \
--user "myUser:myPW" \
--data \
"myMetric,hostname=myHost,type=hwthread,type-id=0,unit=Hz value=400000i 1694777161164284635
myMetric,hostname=myHost,type=hwthread,type-id=1,unit=Hz value=400001i 1694777161164284635"
```
