NetData – Monitor Everything in Real-time

Netdata is distributed, real-time, performance and health monitoring for systems and applications. It is a highly-optimized monitoring agent you install on all your systems and containers.

This tool provides unparalleled insights, in real-time, of everything happening on the systems it runs (including web servers, databases, applications), using highly interactive web dashboards. It can run autonomously, without any third-party components, or it can be integrated to existing monitoring toolchains (Prometheus, Graphite, OpenTSDB, Kafka, Grafana, and more).

NetData – Monitor Everything in Real-time

Netdata is fast and efficient, designed to permanently run on all systems (physical & virtual servers, containers, IoT devices), without disrupting their core function.

Some of the features provided by this program are:

  • 1s granularity – The highest possible resolution for all metrics.
  • Unlimited metrics – collects all the available metrics—the more, the better.
  • 1% CPU utilization of a single core.
  • A few MB of RAM – The low-memory round-robin option uses 25MB RAM, and you can resize it.
  • Minimal disk I/O – While running, only writes historical metrics and reads error and access logs.
  • Zero configuration – auto-detects everything, and can collect up to 10,000 metrics per server out of the box.
  • Zero maintenance – You just run it. The tool does the rest.
  • Zero dependencies – runs a custom web server for its static web files and its web API (though its plugins may require additional libraries, depending on the applications monitored).
  • Scales to infinity – You can install it on all your servers, containers, VMs, and IoT devices. Metrics are not centralized by default, so there is no limit.
  • Several operating modes – Autonomous host monitoring (the default), headless data collector, forwarding proxy, store and forward proxy, central multi-host monitoring, in all possible configurations. Each node may have different metrics retention policies and run with or without health monitoring.
