Installing Node Exporter from Prometheus binary releases
Configuring Prometheus to Scrape Node Exporter
Because Prometheus only scrapes exporters which are defined in the scrape_configs portion of its configuration file, we'll need to add an entry for Node Exporter, just like we did for Prometheus itself.
At the end of the scrape_configs block, add a new entry called node_exporter.
sudo nano /etc/prometheus/prometheus.yml
global: scrape_interval: 15s
scrape_configs: - job_name: 'prometheus' scrape_interval: 5s static_configs: - targets: ['localhost:9090'] - job_name: 'node_exporter' scrape_interval: 5s static_configs:
- targets: ['localhost:9100']
Finally, restart Prometheus to put the changes into effect and verify status
docker restart prometheus
