## What is Netdata ?

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.

You can install Netdata on most Linux distributions (Ubuntu, Debian, CentOS, and more), container platforms (Kubernetes
clusters, Docker), and many other operating systems (FreeBSD).

Netdata is:

### Simple to deploy

-   **One-line deployment** for Linux distributions, plus support for Kubernetes/Docker infrastructures.
-   **Zero configuration and maintenance** required to collect thousands of metrics, every second, from the underlying
    OS and running applications.
-   **Prebuilt charts and alarms** alert you to common anomalies and performance issues without manual configuration.
-   **Distributed storage** to simplify the cost and complexity of storing metrics data from any number of nodes.

### Powerful and scalable

-   **1% CPU utilization, a few MB of RAM, and minimal disk I/O** to run the monitoring Agent on bare metal, virtual
    machines, containers, and even IoT devices.
-   **Per-second granularity** for an unlimited number of metrics based on the hardware and applications you're running
    on your nodes.
-   **Interoperable exporters** let you connect Netdata's per-second metrics with an existing monitoring stack and other
    time-series databases.

### Optimized for troubleshooting

-   **Visual anomaly detection** with a UI/UX that emphasizes the relationships between charts.
-   **Customizable dashboards** to pinpoint correlated metrics, respond to incidents, and help you streamline your
    workflows.
-   **Distributed metrics in a centralized interface** to assist users or teams trace complex issues between distributed
    nodes.

### Secure by design

-   **Distributed data architecture**  so fast and efficient, there’s no limit to the number of metrics you can follow. 
-   Because your data is **stored at the edge**, security is ensured.
-   
### Comparison with other monitoring solutions

Netdata offers many benefits over the existing monitoring landscape, whether they're expensive SaaS products or other
open-source tools.

| Netdata                                                         | Others (open-source and commercial)                              |
| :-------------------------------------------------------------- | :--------------------------------------------------------------- |
| **High resolution metrics** (1s granularity)                    | Low resolution metrics (10s granularity at best)                 |
| Collects **thousands of metrics per node**                      | Collects just a few metrics                                      |
| Fast UI optimized for **anomaly detection**                     | UI is good for just an abstract view                             |
| **Long-term, autonomous storage** at one-second granularity     | Centralized metrics in an expensive data lake at 10s granularity |
| **Meaningful presentation**, to help you understand the metrics | You have to know the metrics before you start                    |
| Install and get results **immediately**                         | Long sales process and complex installation process              |
| Use it for **troubleshooting** performance problems             | Only gathers _statistics of past performance_                    |
| **Kills the console** for tracing performance issues            | The console is always required for troubleshooting               |
| Requires **zero dedicated resources**                           | Require large dedicated resources                                |


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://github.com/netdata/netdata/blob/master/collectors/COLLECTORS.md).
-   **20+ notification platforms**: Netdata's health watchdog sends warning and critical alarms to your [favorite
    platform](https://github.com/netdata/netdata/blob/master/docs/monitor/enable-notifications.md) 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://github.com/netdata/netdata/blob/master/docs/export/external-databases.md) for best-in-class
    interoperability.


## 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.

You can see a high level representation in the following diagram.

And a higher level diagram in this one.

You can even visit this slightly dated [interactive infographic](https://my-netdata.io/infographic.html) and get lost in a rabbit hole. 

But the best way to get under the hood or in the steering wheel of our highly efficient, low-latency system (supporting multiple readers and one writer on each metric) is to read the rest of our docs, or just to jump in and [get started](app.netdata.com). But here's a good breakdown:

### Netdata Agent

Netdata's distributed monitoring Agent collects thousands of metrics from systems, hardware, and applications with zero configuration. It runs permanently on all your physical/virtual servers, containers, cloud deployments, and edge/IoT devices.

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

### Netdata Cloud
Netdata Cloud is a web application that gives you real-time visibility for your entire infrastructure. With Netdata Cloud, you can view key metrics, insightful charts, and active alarms from all your nodes in a single web interface. When an anomaly strikes, seamlessly navigate to any node to troubleshoot and discover the root cause with the familiar Netdata dashboard.

Netdata Cloud is free! You can add an entire infrastructure of nodes, invite all your colleagues, and visualize any number of metrics, charts, and alarms entirely for free.

While Netdata Cloud offers a centralized method of monitoring your Agents, your metrics data is not stored or centralized in any way. Metrics data remains with your nodes and is only streamed to your browser, through Cloud, when you're viewing the Netdata Cloud interface.

## 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](https://news.ycombinator.com/item?id=3067434):_

> Note to self: Starting immediately, all raganwald projects will have a “Is it any good?” section in the readme, and
