Quick VM Monitoring

This is a Docker Compose workspace to quickly setup Linux VM monitoring using Grafana, Prometheus, and Node Exporter. The dashboard used is taken from rfmoz's Node Exporter Full Dashboard.

Requirements

You need to have Docker and Docker Compose installed. Running the Compose file enables privileged mode by default for the node-exporter service. You can remove it but with an exchange for not being able to monitor dbus.

Quick Start

1. Rename grafana.env.example to grafana.env and set GF_SECURITY_ADMIN_PASSWORD for Grafana dashboard admin password.

2. Run docker compose up -d.

3. Access the dashboard at http://localhost:3000.

Additional Configurations

• By default, Prometheus retention is set to maximum storage size of 10GB. You can modify this with --storage.tsdb.retention.size. Read more here.

• If you're exposing the dashboard behind reverse proxy for a domain, set GF_SERVER_DOMAIN in gravana.env to your domain. Read more here and here.
