## `prometheus` sink
|
||
|
|
|
||
|
|
The `prometheus` sink publishes all metrics via an HTTP server ready to be scraped by a [Prometheus](https://prometheus.io) server. It creates gauge metrics for all node metrics and gauge vectors for all metrics with a subtype like 'device', 'cpu' or 'socket'.
|
||
|
|
|
||
|
|
|
||
|
|
### Configuration structure
|
||
|
|
|
||
|
|
```json
|
||
|
|
{
|
||
|
|
"<name>": {
|
||
|
|
"type": "prometheus",
|
||
|
|
"host": "localhost",
|
||
|
|
"port": "8080",
|
||
|
|
"path": "metrics"
|
||
|
|
}
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
- `type`: makes the sink an `prometheus` sink
|
||
|
|
- `host`: The HTTP server gets bound to that IP/hostname
|
||
|
|
- `port`: Portnumber (as string) for the HTTP server
|
||
|
|
- `path`: Path where the metrics should be servered. The metrics will be published at `host`:`port`/`path`
|
||
|
|
- `group_as_namespace`: Most metrics contain a group as meta information like 'memory', 'load'. With this the metric names are extended to `group`_`name` if possible.
