netdata

Netdata is high-fidelity infrastructure monitoring and troubleshooting.
Open-source, free, preconfigured, opinionated, and always real-time.

Netdata's distributed, real-time monitoring Agent collects thousands of metrics from systems, hardware, containers, and applications with zero configuration. It runs permanently on all your physical/virtual servers, containers, cloud deployments, and edge/IoT devices, and is perfectly safe to install on your systems mid-incident without any preparation.

You can install Netdata on most Linux distributions (Ubuntu, Debian, CentOS, and more), container platforms (Kubernetes clusters, Docker), and many other operating systems (FreeBSD, macOS). No sudo required.

Netdata is designed by system administrators, DevOps engineers, and developers to collect everything, help you visualize metrics, troubleshoot complex performance problems, and make data interoperable with the rest of your monitoring stack.

People get addicted to Netdata. Once you use it on your systems, there's no going back! You've been warned...

Latest release: v1.28.0, December 18, 2020

Release v1.28.0 is a hotfix release to address a deadlock in the Netdata Agent. We intended to release this hotfix as v1.27.1, but we can't backtrack on a release once we've begun to publish new Docker images and binary packages on other platforms.

v1.27.0, December 17, 2020

The v1.27.0 release of the Netdata Agent brings dramatic improvements to long-term metrics storage via the database engine, and new dashboard features like a time & date picker for visualizing precise timeframes. Two new collectors bring incredible new value to existing features, including a bit of machine learning magic.

Features

Here's what you can expect from Netdata:

• 1s granularity: The highest possible resolution for all metrics.
• Unlimited metrics: Netdata collects all the available metrics—the more, the better.
• 1% CPU utilization of a single core: It's unbelievably optimized.
• A few MB of RAM: The highly-efficient database engine stores per-second metrics in RAM and then "spills" historical metrics to disk long-term storage.
• Minimal disk I/O: While running, Netdata only writes historical metrics and reads error and access logs.
• Zero configuration: Netdata auto-detects everything, and can collect up to 10,000 metrics per server out of the box.
• Zero maintenance: You just run it. Netdata does the rest.
• Stunningly fast, interactive visualizations: The dashboard responds to queries in less than 1ms per metric to synchronize charts as you pan through time, zoom in on anomalies, and more.
• Visual anomaly detection: Our UI/UX emphasizes the relationships between charts to help you detect the root cause of anomalies.
• 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. Use different metrics retention policies per node and run with or without health monitoring.

Netdata works with tons of applications, notifications platforms, and other time-series databases:

• 300+ system, container, and application endpoints: Collectors autodetect metrics from default endpoints and immediately visualize them into meaningful charts designed for troubleshooting. See everything we support.
• 20+ notification platforms: Netdata's health watchdog sends warning and critical alarms to your favorite platform to inform you of anomalies just seconds after they affect your node.
• 30+ external time-series databases: Export resampled metrics as they're collected to other local- and Cloud-based databases for best-in-class interoperability.

Get Netdata

To install Netdata from source on most Linux systems (physical, virtual, container, IoT, edge), run our one-line installation script. This script downloads and builds all dependencies, including those required to connect to Netdata Cloud if you choose, and enables automatic nightly updates and anonymous statistics.

bash <(curl -Ss https://my-netdata.io/kickstart.sh)

To view the Netdata dashboard, navigate to http://localhost:19999, or http://NODE:19999.

Docker

You can also try out Netdata's capabilities in a Docker container:

docker run -d --name=netdata \
  -p 19999:19999 \
  -v netdataconfig:/etc/netdata \
  -v netdatalib:/var/lib/netdata \
  -v netdatacache:/var/cache/netdata \
  -v /etc/passwd:/host/etc/passwd:ro \
  -v /etc/group:/host/etc/group:ro \
  -v /proc:/host/proc:ro \
  -v /sys:/host/sys:ro \
  -v /etc/os-release:/host/etc/os-release:ro \
  --restart unless-stopped \
  --cap-add SYS_PTRACE \
  --security-opt apparmor=unconfined \

Other operating systems

See our documentation for additional operating systems, including Kubernetes, .deb/.rpm packages, and more.

Post-installation

When you're finished with installation, check out our single-node or infrastructure monitoring quickstart guides based on your use case.

Or, skip straight to configuring the Netdata Agent.

Read through Netdata's documentation, which is structured based on actions and solutions, to enable features like health monitoring, alarm notifications, long-term metrics storage, exporting to external databases, and more.

How it works

Netdata is a highly efficient, highly modular, metrics management engine. Its lockless design makes it ideal for concurrent operations on the metrics.

The result is a highly efficient, low-latency system, supporting multiple readers and one writer on each metric.

Is it any good?

Yes.

When people first hear about a new product, they frequently ask if it is any good. A Hacker News user remarked:

Note to self: Starting immediately, all raganwald projects will have a “Is it any good?” section in the readme, and the answer shall be “yes.".

So, we follow the tradition...
