What Makes Netdata Special


Per-Second Granularity

Most monitoring tools collect every 15-60 seconds. Netdata collects every second. You see spikes, micro-outages, and patterns that other tools miss.


Zero Configuration

Install Netdata and it immediately monitors everything: CPU, memory, disk, network, containers, databases, web servers. No configuration files needed.


Beautiful Dashboards

Built-in interactive dashboards with real-time streaming. Zoom, pan, and drill into any metric.


Low Overhead

Netdata uses about 1% CPU and 100 MB RAM while monitoring 2,000+ metrics per second.


What It Monitors (Automatically)


System

  • CPU per core
  • Memory (used, cached, buffers)
  • Disk I/O and space
  • Network interfaces
  • System load
  • Processes

    • Containers

  • Per-container CPU and memory
  • Container network I/O
  • Container disk I/O

    • Applications

  • Nginx/Apache requests
  • PostgreSQL/MySQL queries
  • Redis operations
  • Node.js/Python metrics

    • Netdata vs Prometheus + Grafana


    Netdata

  • Zero setup, immediate results
  • Per-second granularity
  • Built-in dashboards
  • Single tool
  • Limited long-term storage

    • Prometheus + Grafana

  • More customizable
  • Better for custom metrics
  • Long-term storage
  • More complex setup
  • Industry standard

    • Use Netdata for quick real-time monitoring. Use Prometheus + Grafana for production observability.


    Deployment


    1. Deploy Netdata on TinyPod

    2. Access the dashboard

    3. Everything is already being monitored


    Resources: 1 CPU, 256 MB RAM.


    Alerting
