## `nats` sink
|
|
|
|
|
|
|
|
|
|
The `nats` sink publishes all metrics into a NATS network. The publishing key is the database name provided in the configuration file
|
|
|
|
|
|
|
|
|
|
### Configuration structure
|
|
|
|
|
|
|
|
|
|
```json

|
|
}
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
- `type`: makes the sink an `nats` sink
|
|
|
|
|
- `database`: All metrics are published with this subject
|
|
|
|
|
- `host`: Hostname of the NATS server

### Using `nats` sink for communication with cc-metric-store
|
|
|
|
|
|
|
|
|
|
The cc-metric-store only accepts metrics with a timestamp precision in seconds, so it is required to use `"precision": "s"`.
