Installing Node Exporter[edit]
- Linux:
apt install prometheus-node-exporter - macOS:
brew install node_exporter - Docker Hub:
docker pull prom/node-exporter && docker run prom/node-exporter(not recommended to deploy it as a Docker container [1])
systemctl config files:
prometheus-node-exporter.serviceprometheus-node-exporter-apt.timer
Installing Node Exporter from Prometheus binary releases[edit]
Configuring Prometheus to Scrape Node Exporter[edit]
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
