netdata

New to netdata? Here is a live demo: http://my-netdata.io

netdata is a system for distributed real-time performance and health monitoring.
It provides unparalleled insights, in real-time, of everything happening on the
system it runs (including applications such as web and database servers), using
modern interactive web dashboards.

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

netdata runs on Linux, FreeBSD, and MacOS.

  • Stunning interactive bootstrap dashboards<br/>
    mouse and touch friendly, in 2 themes: dark, light

  • Amazingly fast<br/>
    responds to all queries in less than 0.5 ms per metric,
    even on low-end hardware

  • Highly efficient<br/>
    collects thousands of metrics per server per second,
    with just 1% CPU utilization of a single core, a few MB of RAM and no disk I/O at all

  • Sophisticated alarming<br/>
    hundreds of alarms, out of the box!<br/>
    supports dynamic thresholds, hysteresis, alarm templates,
    multiple role-based notification methods (such as email, slack.com,
    pushover.net, pushbullet.com, telegram.org, twilio.com, messagebird.com)

  • Extensible<br/>
    you can monitor anything you can get a metric for,
    using its Plugin API (anything can be a netdata plugin,
    BASH, python, perl, node.js, java, Go, ruby, etc)

  • Embeddable<br/>
    it can run anywhere a Linux kernel runs (even IoT)
    and its charts can be embedded on your web pages too

  • Customizable<br/>
    custom dashboards can be built using simple HTML (no javascript necessary)

  • Zero configuration<br/>
    auto-detects everything, it can collect up to 5000 metrics
    per server out of the box

  • Zero dependencies<br/>
    it is even its own web server, for its static web files and its web API

  • Zero maintenance<br/>
    you just run it, it does the rest

  • scales to infinity<br/>
    requiring minimal central resources

  • several operating modes<br/>
    autonomous host monitoring, headless data collector, forwarding proxy, store and forward proxy, central multi-host monitoring, in all possible configurations.
    Each node may have different metrics retention policy and run with or without health monitoring.

  • time-series back-ends supported<br/>
    can archive its metrics on graphite, opentsdb, prometheus, json document DBs, in the same or lower detail
    (lower: to prevent it from congesting these servers due to the amount of data collected)


What does it monitor?

netdata collects several thousands of metrics per device.
All these metrics are collected and visualized in real-time.

Almost all metrics are auto-detected, without any configuration.

This is a list of what it currently monitors:

  • CPU<br/>
    usage, interrupts, softirqs, frequency, total and per core, CPU states

  • Memory<br/>
    RAM, swap and kernel memory usage, KSM (Kernel Samepage Merging), NUMA

  • Disks<br/>
    per disk: I/O, operations, backlog, utilization, space, software RAID (md)

  • Network interfaces<br/>
    per interface: bandwidth, packets, errors, drops

  • IPv4 networking<br/>
    bandwidth, packets, errors, fragments,
    tcp: connections, packets, errors, handshake,
    udp: packets, errors,
    broadcast: bandwidth, packets,
    multicast: bandwidth, packets

  • IPv6 networking<br/>
    bandwidth, packets, errors, fragments, ECT,
    udp: packets, errors,
    udplite: packets, errors,
    broadcast: bandwidth,

    icmp: messages, errors, echos, router, neighbor, MLDv2, group membership,
    break down by type
