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](https://github.com/netdata/netdata/releases/latest): v1.31.0, May 19, 2021**
>
> The v1.31.0 release of Netdata comes with re-packaged and redesigned elements of the dashboard to help you focus on
> your metrics, even more Linux kernel insights via eBPF, on-node machine learning to help you find anomalies, and much
> more.

## 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](https://learn.netdata.cloud/docs/agent/collectors/collectors).
- **20+ notification platforms**: Netdata's health watchdog sends warning and critical alarms to your [favorite
platform](https://learn.netdata.cloud/docs/monitor/enable-notifications) 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](https://learn.netdata.cloud/docs/export/external-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](https://learn.netdata.cloud/docs/agent/packaging/installer/methods/packages). This script downloads
and builds all dependencies, including those required to connect to [Netdata Cloud](https://netdata.cloud/cloud) if you
choose, and enables [automatic nightly
updates](https://learn.netdata.cloud/docs/agent/packaging/installer#nightly-vs-stable-releases) and [anonymous
statistics](https://learn.netdata.cloud/docs/agent/anonymous-statistics).
```bash
wget -O /tmp/netdata-kickstart.sh https://my-netdata.io/kickstart.sh && sh /tmp/netdata-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](https://learn.netdata.cloud/docs/agent/packaging/docker/):
```bash
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 \
netdata/netdata

solutions, to enable features like health monitoring, alarm notifications, long-term metrics storage, exporting to
external databases, and more.
### Netdata Cloud
Netdata Cloud works with Netdata's free, open-source monitoring agent to help you monitor and troubleshoot every
layer of your systems to find weaknesses before they turn into outages. [Using both tools](https://learn.netdata.cloud/docs/agent/claim)
can help you turn data into insights immediately.

## 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.
