SLV Install - Node Exporter

Why Node Exporter?

Node Exporter exposes detailed hardware and OS metrics—CPU, memory, disk, network—so Prometheus and Grafana can alert on infrastructure issues before they impact Solana workloads. Installing it via slv install ensures every server reports a consistent set of system metrics without manual setup.

Highlights

Node Exporter: https://github.com/prometheus/node_exporter
Lightweight binary with minimal overhead, perfect for bare metal or VPS hosts.
Provides the baseline metrics dashboards and alerts rely on across Prometheus/Grafana.

Observe Ansible Execution

slv runs the Node Exporter playbook and enables it as a systemd service so it starts automatically on boot.

bash
🚀 Running ansible: ansible-playbook -i 1.1.1.1, -u solv /Users/fumi/.slv/template/0.9.800/ansible/cmn/software/install-node-exporter.yml

Verify the Endpoint

After installation, Node Exporter publishes metrics on port 9100. Prometheus should scrape this endpoint to feed dashboards and alerts.

bash
✅ Installation completed successfully!

🌐 Access Information:

Node Exporter URL: http://1.1.1.1:9100/metrics

Dashboard

Visit http://1.1.1.1:9100/metrics to confirm raw output, then add the target in Prometheus and plug predefined Grafana dashboards (e.g., Node Exporter Full) to visualize host health.
