Netdata

Real-time infrastructure monitoring with per-second granularity. Collects thousands of metrics automatically and displays them through an interactive web dashboard.

What You Can Do After Deployment

1. Visit your domain — the Netdata dashboard loads instantly with live metrics
2. Monitor system health — CPU, memory, disk, network, and hundreds more metrics out of the box
3. Inspect containers — view per-container resource usage if Docker is available
4. Set up alerts — built-in health watchdog with preconfigured alarms for common issues
5. Use the API — query any metric via the built-in REST API at /api/v1/data
