To start the exporter:
|
|

```
|
|
prometheus-exporter-merger --config config.yaml
|
|
```
|
|
|
|
Config example:
|
|
|
|
```yaml
|
|
listen: :8080
|
|
scrap_timeout: 20s
|
|
sources:
|
|
- url: http://127.0.0.1:8081/metrics
|
|
labels:
|
|
key1: value1
|
|
- url: http://127.0.0.1:8082/metrics
|
|
labels:
|
|

|
|
```
