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 systems it runs (including containers and applications such as web and database servers), using modern interactive web dashboards.

netdata core values

we value	netdata...
high resolution metrics	collects all metrics every single second
unlimited metrics	collects thousands of metrics per monitored node
real-time visualization	dashboards run with sub-second latency, collection to visualization
powerful anomaly detection	has a distributed watchdog embedded in it, running on all monitored nodes
visual anomaly detection	dashboards are optimized for spotting anomalies, across all metrics
meaningful presentation	dashboards present all metrics in a structured, easy to understand, way
zero configuration	auto-detects all metrics and comes with dozens of alarms
resource utilization	core is optimized C code, using <1% utilization of single CPU core

netdata also supports:

• monitoring ephemeral nodes and auto-scaled containers,
• integration with existing monitoring infrastructure (time-series databases like prometheus, graphite, opentsdb) and third-party event notification methods (like slack, pagerduty, pushover, and dozens more),
• building hierarchies of monitored nodes via real-time metrics streaming between them,
• embedding charts and dashboards on third party web sites and applications, such as Atlassian's Confluence.

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

netdata currently runs on Linux, FreeBSD, and MacOS.

News

Sep 18, 2018 - netdata has its own organization

Netdata used to be a firehol.org project, accessible as firehol/netdata.

Netdata now has its own github organization netdata, so all github URLs are now netdata/netdata. The old github URLs, repo clones, forks, etc redirect automatically to the new repo.

Features

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

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

• Highly efficient
  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 alerting
  hundreds of alarms, out of the box!
  supports dynamic thresholds, hysteresis, alarm templates, multiple role-based notification methods (such as email, slack.com, flock.com, pushover.net, pushbullet.com, telegram.org, twilio.com, messagebird.com, kavenegar.com)

• Extensible
  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
  it can run anywhere a Linux kernel runs (even IoT) and its charts can be embedded on your web pages too

• Customizable
  custom dashboards can be built using simple HTML (no javascript necessary)

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

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

• Zero maintenance
  you just run it, it does the rest

• scales to infinity
  requiring minimal central resources

• several operating modes
  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
  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
  usage, interrupts, softirqs, frequency, total and per core, CPU states

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

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