# Exporters

The role deploys the following Prometheus exporters using the official images:

* Node-Exporter 
* Ethereum-Metrics-Exporter
* Container Advisor

The configuration is defined in templates/dc-observability-agents.yml.j2 file. 

ethereum-metrics-exporter's port is changed to 9091. The default port collided with Prometheus (9090) in single server deployments. Otherwise default configuration is used. 

If you want to use different version of containers you can modify the following variables:

```yaml
ethereum_metrics_exporter_docker_image: ethpandaops/ethereum-metrics-exporter:0.21.0
node_exporter_docker_image: quay.io/prometheus/node-exporter:v1.5.0
cadvisor_docker_image: gcr.io/cadvisor/cadvisor:v0.47.1
```
