MENU: **[WHAT IS NEW](#whats-new-and-coming)** | **[GETTING STARTED](#getting-started)** | **[HOW IT WORKS](#how-it-works)** | **[FAQ](#faq)** | **[DOCS](#book-documentation)** | **[COMMUNITY](#tada-community)** | **[CONTRIBUTE](#pray-contribute)**

Netdata collects metrics per second and presents them in beautiful low-latency dashboards. It is designed to run on all of your physical and virtual servers, cloud deployments, Kubernetes clusters, and edge/IoT devices, to monitor your systems, containers, and applications.

It scales nicely from just a single server to thousands of servers, even in complex multi/mixed/hybrid cloud environments, and given enough disk space it can keep your metrics for years.

**KEY FEATURES**:<br/>

- :boom: **Collects metrics from 800+ integrations**<br/>
  Operating system metrics, container metrics, virtual machines, hardware sensors, applications metrics, OpenMetrics exporters, StatsD, and logs.
  
- :muscle: **Real-Time, Low-Latency, High-Resolution**<br/>
  All metrics are collected per second and are on the dashboard immediately after data collection. Netdata is designed to be fast.

- :face_in_clouds: **Unsupervised Anomaly Detection**<br/>
  Trains multiple Machine-Learning (ML) models for each metric collected and detects anomalies based on the past behavior of each metric individually.

- :fire: **Powerful Visualization**<br/>
  Clear and precise visualization that allows you to quickly understand any dataset, but also to filter, slice and dice the data directly on the dashboard, without the need to learn any query language.

- :bell: **Out of box Alerts**<br/>
  Comes with hundreds of alerts out of the box to detect common issues and pitfalls, revealing issues that can easily go unnoticed. It supports several notification methods to let you know when your attention is needed.

- :sunglasses: **Low Maintenance**<br/>
  Fully automated in every aspect: automated dashboards, out-of-the-box alerts, auto-detection and auto-discovery of metrics, zero-touch machine-learning, easy scalability and high availability, and CI/CD friendly.

- :star: **Open and Extensible**<br/>
  Netdata is a modular platform that can be extended in all possible ways and it also integrates nicely with other monitoring solutions.

  Check also the [Netdata Deployment Strategies](https://learn.netdata.cloud/docs/architecture/deployment-strategies) to decide how to deploy it in your infrastructure.

### 2. **Configure Collectors** :boom:

   Netdata auto-detects and auto-discovers most operating system data sources and applications. However, many data sources require some manual configuration, usually to allow Netdata to get access to the metrics.
   
   - For a detailed list of the 800+ collectors available, check [this guide](https://learn.netdata.cloud/docs/data-collection/).
   - To monitor Windows servers and applications use [this guide](https://learn.netdata.cloud/docs/data-collection/monitor-anything/system-metrics/windows-machines).
   - To monitor SNMP devices check [this guide](https://learn.netdata.cloud/docs/data-collection/monitor-anything/networking/snmp).

### 3. **Configure Alert Notifications** :bell:

   Netdata comes with hundreds of pre-configured alerts, that automatically check your metrics, immediately after they start getting collected.

   Netdata can dispatch alert notifications to multiple third party systems, including: `email`, `Alerta`, `AWS SNS`, `Discord`, `Dynatrace`, `flock`, `gotify`, `IRC`, `Matrix`, `MessageBird`, `Microsoft Teams`, `ntfy`, `OPSgenie`, `PagerDuty`, `Prowl`, `PushBullet`, `PushOver`, `RocketChat`, `Slack`, `SMS tools`, `StackPulse`, `Syslog`, `Telegram`, `Twilio`.

   By default, Netdata will send e-mail notifications, if there is a configured MTA on the system. 

### 4. **Configure Netdata Parents** :family:

   Optionally, configure one or more Netdata Parents. A Netdata Parent is a Netdata Agent that has been configured to accept [streaming connections](https://learn.netdata.cloud/docs/streaming/streaming-configuration-reference) from other Netdata agents.
   
   Netdata Parents provide:

   - **Infrastructure level dashboards, at `http://parent.server.ip:19999/`.**<br/>
   
     Each Netdata Agent has an API listening at the TCP port 19999 of each server.
     When you hit that port with a web browser (e.g. `http://server.ip:19999/`), the Netdata Agent UI is presented.
     When the Netdata Agent is also a Parent, the UI of the Parent includes data for all nodes that stream metrics to that Parent.
     
   - **Increased retention for all metrics of all your nodes.**<br/>
   
     Each Netdata Agent maintains each own database of metrics. But Parents can be given additional resources to maintain a much longer database than
     individual Netdata Agents.
    
   - **Central configuration of alerts and dispatch of notifications.**<br/>
   
     Using Netdata Parents, all the alert notifications integrations can be configured only once, at the Parent and they can be disabled at the Netdata Agents.

   You can also use Netdata Parents to:

   - Offload your production systems (the parents run ML, alerts, queries, etc. for all their children)
   - Secure your production systems (the parents accept user connections, for all their children)

### 5. **Connect to Netdata Cloud** :cloud:

   Optionally, [sign-in](https://app.netdata.cloud/sign-in) to [Netdata Cloud](https://www.netdata.cloud/) and claim your Netdata Agents and Parents.
   If you connect your Netdata Parents, there is no need to connect your Netdata Agents. They will be connected via the Parents.
   
   When your Netdata nodes are connected to Netdata Cloud, you can (on top of the above):

   - Organize your infra in spaces and rooms
   - Create, manage, and share **custom dashboards**
   - Invite your team and assign roles to them (Role Based Access Control - RBAC)
   - Access Netdata Functions (processes top from the UI and more)
   - Get infinite horizontal scalability (multiple independent parents are viewed as one infra)
   - Configure alerts from the UI (coming soon)
   - Configure data collection from the UI (coming soon)
   - Netdata Mobile App notifications (coming soon)

   :love_you_gesture: Netdata Cloud does not prevent you from using your Netdata Agents and Parents directly, and vice versa.<br/>
   
   :ok_hand: Your metrics are still stored in your network when you connect your Netdata Agents and Parents to Netdata Cloud.

![Netdata Agent 2](https://github.com/netdata/netdata/assets/2662304/49981d85-89b9-4b95-8e45-da7a39e6dd48)

<hr class="solid">

## How it works

Netdata is built around a **modular metrics processing pipeline**.

<details><summary>Click to see more details about this pipeline...</summary>
&nbsp;<br/>

Each Netdata Agent can perform the following functions:

1. **`COLLECT` metrics from their sources**<br/>
   Uses [internal](https://github.com/netdata/netdata/tree/master/collectors) and [external](https://github.com/netdata/go.d.plugin/tree/master/modules) plugins to collect data from their sources.

   Netdata auto-detects and collects almost everything from the operating system: including CPU, Interrupts, Memory, Disks, Mount Points, Filesystems, Network Stack, Network Interfaces, Containers, VMs, Processes, SystemD Units, Linux Performance Metrics, Linux eBPF, Hardware Sensors, IPMI, and more.

   It collects application metrics from applications: PostgreSQL, MySQL/MariaDB, Redis, MongoDB, Nginx, Apache, and hundreds more.

   Netdata also collects your custom application metrics by scraping OpenMetrics exporters, or via StatsD.

   It can convert web server log files to metrics and apply ML and alerts to them, in real-time.

   And it also supports synthetic tests / white box tests, so you can ping servers, check API responses, or even check filesystem files and directories to generate metrics, train ML and run alerts and notifications on their status.
   
2. **`STORE` metrics to a database**<br/>
   Uses database engine plugins to store the collected data, either in memory and/or on disk. We have developed our own [`dbengine`](https://github.com/netdata/netdata/tree/master/database/engine#readme) for storing the data in a very efficient manner, allowing Netdata to have less than 1 byte per sample on disk and amazingly fast queries.
   
3. **`LEARN` the behavior of metrics** (ML)<br/>
   Trains multiple Machine-Learning (ML) models per metric to learn the behavior of each metric individually. Netdata uses the `kmeans` algorithm and creates by default a model per metric per hour, based on the values collected for that metric over the last 6 hours. The trained models are persisted to disk.
   
4. **`DETECT` anomalies in metrics** (ML)<br/>
   Uses the trained machine learning (ML) models to detect outliers and mark collected samples as **anomalies**. Netdata stores anomaly information together with each sample and also streams it to Netdata Parents so that the anomaly is also available at query time for the whole retention of each metric.

5. **`CHECK` metrics and trigger alert notifications**<br/>
   Uses its configured alerts (you can configure your own) to check the metrics for common issues and uses notifications plugins to send alert notifications.

6. **`STREAM` metrics to other Netdata Agents**<br/>
   Push metrics in real-time to Netdata Parents.

7. **`ARCHIVE` metrics to 3rd party databases**<br/>
   Export metrics to industry standard time-series databases, like `Prometheus`, `InfluxDB`, `OpenTSDB`, `Graphite`, etc.

8. **`QUERY` metrics and present dashboards**<br/>
   Provide an API to query the data and present interactive dashboards to users.

9. **`SCORE` metrics to reveal similarities and patterns**<br/>
   Score the metrics according to the given criteria, to find the needle in the haystack.

When using Netdata Parents, all the functions of a Netdata Agent (except data collection) can be delegated to Parents to offload production systems.

The core of Netdata is developed in C. We have our own `libnetdata`, that provides:

- **`DICTIONARY`**<br/>
  A high-performance algorithm to maintain both indexed and ordered pools of structures Netdata needs. It uses JudyHS arrays for indexing, although it is modular: any hashtable or tree can be integrated into it. Despite being in C, dictionaries follow object-oriented programming principles, so there are constructors, destructors, automatic memory management, garbage collection, and more. For more see [here](https://github.com/netdata/netdata/tree/master/libnetdata/dictionary).
  
- **`ARAL`**<br/>
  ARray ALlocator (ARAL) is used to minimize the system allocations made by Netdata. ARAL is optimized for peak performance when multi-threaded. It also allows all structures that use it to be allocated in memory-mapped files (shared memory) instead of RAM. For more see [here](https://github.com/netdata/netdata/tree/master/libnetdata/aral).

- **`PROCFILE`**<br/>
  A high-performance `/proc` (but also any) file parser and text tokenizer. It achieves its performance by keeping files open and adjustings its buffers to read the entire file in one call (which is also required by the Linux kernel). For more see [here](https://github.com/netdata/netdata/tree/master/libnetdata/procfile).

- **`STRING`**<br/>
  A string internet mechanism, for string deduplication and indexing (using JudyHS arrays), optimized for multi-threaded usage. For more see [here](https://github.com/netdata/netdata/tree/master/libnetdata/string).

- **`ARL`**<br/>
  Adaptive Resortable List (ARL), is a very fast list iterator, that keeps the expected items on the list in the same order they are found in input list. So, the first iteration is somewhat slower, but all the following iterations are perfectly aligned for best performance. For more see [here](https://github.com/netdata/netdata/tree/master/libnetdata/adaptive_resortable_list).

- **`BUFFER`**<br/>
  A flexible text buffer management system that allows Netdata to automatically handle dynamically sized text buffer allocations. The same mechanism is used for generating consistent JSON output by the Netdata APIs. For more see [here](https://github.com/netdata/netdata/tree/master/libnetdata/buffer).

- **`SPINLOCK`**<br/>
  Like POSIX `MUTEX` and `RWLOCK` but a lot faster, based on atomic operations, with significantly smaller memory impact, while being portable.

- **`PGC`**<br/>
  A caching layer that can be used to cache any kind of time-related data, with automatic indexing (based on a tree of JudyL arrays), memory management, evictions, flushing, pressure management. This is extensively used in `dbengine`. For more see [here](https://github.com/netdata/netdata/blob/master/database/engine/README.md).

The above, and many more, allow Netdata developers to work on the application fast and with confidence. Most of the business logic in Netdata is a work of mixing the above.

Netdata data collection plugins can be developed in any language. Most of our application collectors though are developed in [Go](https://github.com/netdata/go.d.plugin).

## FAQ

### :shield: Is Netdata secure?

Of course it is! We do our best to ensure it is!

<details><summary>Click to see detailed answer ...</summary>
&nbsp;<br/>&nbsp;<br/>

We understand that Netdata is a software piece that is installed on millions of production systems across the world. So, it is important for us, Netdata to be as secure as possible:

  - We follow the [Open Source Security Foundation](https://bestpractices.coreinfrastructure.org/en/projects/2231) best practices.
  - We have given great attention to detail when it comes to security design. Check out our [security design](https://learn.netdata.cloud/docs/architecture/security-and-privacy-design).
  - Netdata is a popular open-source project and is frequently tested by many security analysts.
  - Check also our [security policies and advisories published so far](https://github.com/netdata/netdata/security).

### :cyclone: Will Netdata consume significant resources on my servers?

No. It will not! We promise this will be fast!

<details><summary>Click to see detailed answer ...</summary>
&nbsp;<br/>&nbsp;<br/>

Although each Netdata Agent is a complete monitoring solution packed into a single application, and despite the fact that Netdata collects **every metric every single second** and trains **multiple ML models** per metric, you will find that Netdata has amazing performance! In many cases, it outperforms other monitoring solutions that have significantly fewer features or far smaller data collection rates.

This is what you should expect:

  - For production systems, each Netdata Agent with default settings (everything enabled, ML, Health, DB) should consume about 5% CPU utilization of one core and about 150 MiB or RAM.

    By using a Netdata parent and streaming all metrics to that parent, you can disable ML & health and use an ephemeral DB mode (like `alloc`) on the children, leading to utilization of about 1% CPU of a single core and 100 MiB of RAM. Of course, these depend on how many metrics are collected.
    
  - For Netdata Parents, for about 1 to 2 million metrics, all collected every second, we suggest a server with 16 cores and 32GB RAM. Less than half of it will be used for data collection and ML. The rest will be available for queries.

Netdata has extensive internal instrumentation to help us reveal how the resources consumed are used. All these are available in the "Netdata Monitoring" section of the dashboard. Depending on your use case, there are many options to optimize resource consumption.

Even if you need to run Netdata on extremely weak embedded or IoT systems, you will find that Netdata can be tuned to be very performant.

&nbsp;<br/>&nbsp;<br/>
</details>

### :scroll: How much retention can I have?

As much as you need!

<details><summary>Click to see detailed answer ...</summary>
&nbsp;<br/>&nbsp;<br/>

Netdata supports **tiering**, to downsample past data and save disk space. With default settings, it has 3 tiers:

  1. `tier 0`, with high resolution, per-second, data.
  2. `tier 1`, mid-resolution, per minute, data.
  3. `tier 2`, low-resolution, per hour, data.

All tiers are updated in parallel during data collection. Just increase the disk space you give to Netdata to get a longer history for your metrics. Tiers are automatically chosen at query time depending on the time frame and the resolution requested.

&nbsp;<br/>&nbsp;<br/>
</details>

### :rocket: Does it scale? I have really a lot of servers!

Netdata is designed to scale and can handle large volumes of data.

<details><summary>Click to see detailed answer ...</summary>
&nbsp;<br/>&nbsp;<br/>
Netdata is a distributed monitoring solution. You can scale it to infinity by spreading Netdata servers across your infrastructure.

With the streaming feature of the Agent, we can support monitoring ephemeral servers but also allow the creation of "monitoring islands" where metrics are aggregated to a few servers (Netdata Parents) for increased retention, or for offloading production systems.

  - :airplane: Netdata Parents provide great vertical scalability, so you can have as big parents as the CPU, RAM and Disk resources you can dedicate to them. In our lab we constantly stress test Netdata Parents with several million metrics collected per second, to ensure it is reliable, stable, and robust at scale.
    
  - :rocket: In addition, Netdata Cloud provides virtually unlimited horizontal scalability. It "merges" all the Netdata parents you have into one unified infrastructure at query time. Netdata Cloud itself is probably the biggest single installation monitoring platform ever created, currently monitoring about 100k online servers with about 10k servers changing state (added/removed) per day!

Example: the following chart comes from a single Netdata Parent. As you can see on it, 244 nodes stream to it metrics of about 20k running containers. On this specific chart there are 3 dimensions per container, so a total of about 60k time-series queries are needed to present it.

</details>

### :floppy_disk: My production servers are very sensitive in disk I/O. Can I use Netdata?

Yes, you can!

<details><summary>Click to see detailed answer ...</summary>
&nbsp;<br/>&nbsp;<br/>

Netdata has been designed to spread disk writes across time. Each metric is flushed to disk every 17 minutes, but metrics are flushed evenly across time, at an almost constant rate. Also, metrics are packed into bigger blocks we call `extents` and are compressed with LZ4 before saving them, to minimize the number of I/O operations made.

Single node Agents (not Parents), should have a constant rate of about 50 KiB/s or less, with some spikes above that every minute (flushing of tier 1) and higher spikes every hour (flushing of tier 2).

Health Alerts and Machine-Learning run queries to evaluate their expressions and learn from the metrics' patterns. These are also spread over time, so there should be an almost constant read rate too.

To make Netdata not use the disks at all, we suggest the following:

  1. Use database mode `alloc` or `ram` to disable writing metric data to disk.
  2. Configure streaming to push in real-time all metrics to a Netdata Parent. The Netdata Parent will maintain metrics on disk for this node.
  3. Disable ML and health on this node. The Netdata Parent will do them for this node.
  4. Use the Netdata Parent to access the dashboard.

Using the above, the Netdata Agent on your production system will not use a disk.

### :raised_eyebrow: How is Netdata different from a Prometheus and Grafana setup?

Netdata is a "ready to use" monitoring solution. Prometheus and Grafana are tools to build your own monitoring solution.

<details><summary>Click to see detailed answer ...</summary>
&nbsp;<br/>&nbsp;<br/>

First, we have to say that Prometheus as a time-series database and Grafana as a visualizer are excellent tools for what they do.

However, we believe that such a setup is missing a key element: A Prometheus and Grafana setup assumes that you know everything about the metrics you collect and you understand deeply how they are structured, they should be queried and visualized.

In reality, this setup has a lot of problems. The vast number of technologies, operating systems, and applications we use in our modern stacks, makes it impossible for any single person to know and understand everything about anything. We get testimonials regularly from Netdata users across the biggest enterprises, that Netdata manages to reveal issues, anomalies and problems they were not aware of and they didn't even have the means to find or troubleshoot.

So, the biggest difference of Netdata to Prometheus, and Grafana, is that we decided that the tool needs to have a much better understanding of the components, the applications, and the metrics it monitors.

  - When compared to Prometheus, Netdata needs for each metric much more than just a name, some labels, and a value over time. A metric in Netdata is a structured entity that correlates with other metrics in a certain way and has specific attributes that depict how it should be organized, treated, queried, and visualized. We call this the NIDL (Nodes, Instances, Dimensions, Labels) framework.

    Maintaining such an index is a challenge: first, because the raw metrics collected do not provide this information, so we have to add it, and second because we need to maintain this index for the lifetime of each metric, which with our current database retention, it is usually more than a year.

  - When compared to Grafana, Netdata is fully automated. Grafana has more customization capabilities than Netdata, but Netdata presents fully functional dashboards by itself and most importantly it gives you the means to understand, analyze, filter, slice and dice the data without the need for you to edit queries or be aware of any peculiarities the underlying metrics may have.

    Furthermore, to help you when you need to find the needle in the haystack, Netdata has advanced troubleshooting tools provided by the Netdata metrics scoring engine, that allows it to score metrics based on their anomaly rate, their differences or similarities for any given time frame.

Still, if you are already familiar with Prometheus and Grafana, Netdata integrates nicely with them, and we have reports from users who use Netdata with Prometheus and Grafana in production.

### :raised_eyebrow: How is Netdata different from DataDog, New Relic, Dynatrace, X SaaS Provider?

With Netdata your data are always on-prem and your metrics are always high-resolution.

<details><summary>Click to see detailed answer ...</summary>
&nbsp;<br/>&nbsp;<br/>

Most commercial monitoring providers face a significant challenge: they centralize all metrics to their infrastructure and this is, inevitably, expensive. It leads them to one or more of the following:

  1. be unrealistically expensive
  2. limit the number of metrics they collect
  3. limit the resolution of the metrics they collect

As a result, they try to find a balance: collect the least possible data, but collect enough to have something useful out of it.

We, at Netdata, see monitoring in a completely different way: **monitoring systems should be built bottom-up and be rich in insights**, so we focus on each component individually to collect, store, check and visualize everything related to each of them, and we make sure that all components are monitored. Each metric is important.

This is why Netdata trains multiple machine-learning models per metric, based exclusively on their own past (no sampling of data, no sharing of trained models) to detect anomalies based on the specific use case and workload each component is used.

This is also why Netdata alerts are attached to components (instances) and are configured with dynamic thresholds and rolling windows, instead of static values.

The distributed nature of Netdata helps scale this approach: your data is spread inside your infrastructure, as close to the edge as possible. Netdata is not one data lane. Each Netdata Agent is a data lane and all of them together build a massive distributed metrics processing pipeline that ensures all your infrastructure components and applications are monitored and operating as they should.

&nbsp;<br/>&nbsp;<br/>
</details>

### :raised_eyebrow: How is Netdata different from Nagios, Icinga, Zabbix, etc?

Netdata offers real-time, comprehensive monitoring, with a user-friendly interface and the ability to monitor everything, without any custom configuration required.

<details><summary>Click to see detailed answer ...</summary>
&nbsp;<br/>&nbsp;<br/>

While Nagios, Icinga, Zabbix, and other similar tools are powerful and highly customizable, they can be complex to set up and manage. Their flexibility often comes at the cost of ease-of-use, especially for users who are not systems administrators or do not have extensive experience with these tools. Additionally, these tools generally require you to know what you want to monitor in advance and configure it explicitly.

Netdata, on the other hand, takes a different approach. It provides a "ready to use" monitoring solution with a focus on simplicity and comprehensiveness. It automatically detects and starts monitoring many different system metrics and applications out-of-the-box, without any need for custom configuration. 

In comparison to these traditional monitoring tools, Netdata:

  - Provides real-time, high-resolution metrics, as opposed to the often minute-level granularity that tools like Nagios, Icinga, and Zabbix provide.

  - Automatically generates meaningful, organized, and interactive visualizations of the collected data. Unlike other tools, where you have to manually create and organize graphs and dashboards, Netdata takes care of this for you.

  - Applies machine learning to each individual metric to detect anomalies, providing more insightful and relevant alerts than static thresholds.

  - Is designed to be distributed, so your data is spread inside your infrastructure, as close to the edge as possible. This approach is more scalable and avoids the potential bottleneck of a single centralized server.

  - Has a more modern and user-friendly interface, making it easy for anyone, not just experienced administrators, to understand the health and performance of their systems.

Even if you're already using Nagios, Icinga, Zabbix, or similar tools, you can use Netdata alongside them to augment your existing monitoring capabilities with real-time insights and user-friendly dashboards.

### :flushed: I feel overwhelmed by the amount of information in Netdata. What should I do?

Netdata is designed to provide comprehensive insights, but we understand that the richness of information might sometimes feel overwhelming. Here are some tips on how to navigate and utilize Netdata effectively...

<details><summary>Click to see detailed answer ...</summary>
&nbsp;<br/>&nbsp;<br/>

Netdata is indeed a very comprehensive monitoring tool. It's designed to provide you with as much information as possible about your system and applications, so that you can understand and address any issues that arise. However, we understand that the sheer amount of data can sometimes be overwhelming.

Here are some suggestions on how to manage and navigate this wealth of information:

  1. **Start with the Overview Dashboard**<br/>
      Netdata's Overview Dashboard provides a high-level summary of your system's status. We have added summary tiles on almost every section, you reveal the information that is more important. This is a great place to start, as it can help you identify any major issues or trends at a glance.

  2. **Use the Search Feature**<br/>
     If you're looking for specific information, you can use the search feature to find the relevant metrics or charts. This can help you avoid scrolling through all the data.

  3. **Customize your Dashboards**<br/>
     Netdata allows you to create custom dashboards, which can help you focus on the metrics that are most important to you. Sign-in to Netdata and there you can have your custom dashboards. (coming soon to the agent dashboard too)

  4. **Leverage Netdata's Anomaly Detection**<br/>
     Netdata uses machine learning to detect anomalies in your metrics. This can help you identify potential issues before they become major problems. We have added an `AR` button above the dashboard table of contents to reveal the anomaly rate per section so that you can easily spot what could need your attention.

  5. **Take Advantage of Netdata's Documentation and Blogs**<br/>
     Netdata has extensive documentation that can help you understand the different metrics and how to interpret them. You can also find tutorials, guides, and best practices there.

Remember, it's not necessary to understand every single metric or chart right away. Netdata is a powerful tool, and it can take some time to fully explore and understand all of its features. Start with the basics and gradually delve into more complex metrics as you become more comfortable with the tool.

### :cloud: Do I have to subscribe to Netdata Cloud?

Subscribing to Netdata Cloud is optional but many users find it enhances their experience with Netdata.

<details><summary>Click to see detailed answer ...</summary>
&nbsp;<br/>&nbsp;<br/>

The Netdata Agent dashboard and the Netdata Cloud dashboard are the same. Still, Netdata Cloud provides additional features, that the Netdata Agent is not capable of. These include:

  1. Customizability (custom dashboards and other settings are persisted when you are signed in to Netdata Cloud)
  2. Configuration of Alerts and Data Collection from the UI (coming soon)
  3. Security (role-based access control - RBAC).
  4. Horizontal Scalability ("blend" multiple independent parents in one uniform infrastructure)
  5. Central Dispatch of Alert Notifications (even when multiple independent parents are involved)
  6. Mobile App for Alert Notifications (coming soon)

So, although it is not required, you can get the most out of your Netdata setup by using Netdata Cloud.

We encourage you to support Netdata by buying a Netdata Cloud subscription. A successful Netdata is a Netdata that evolves and gets improved to provide a simpler, faster and easier monitoring for all of us.

For organizations that need a fully on-prem solution, we provide Netdata Cloud for on-prem installation. [Contact us for more information](mailto:info@netdata.cloud).

### :mag_right: What does the anonymous telemetry collected by Netdata entail?

Your privacy is our utmost priority. As part of our commitment to improving Netdata, we rely on anonymous telemetry data from our users who choose to leave it enabled. This data greatly informs our decision-making processes and contributes to the future evolution of Netdata.

Should you wish to disable telemetry, instructions for doing so are provided in our installation guides.

<details><summary>Click to see detailed answer ...</summary>
&nbsp;<br/>&nbsp;<br/>

Netdata is in a constant state of growth and evolution. The decisions that guide this development are ideally rooted in data. By analyzing anonymous telemetry data, we can answer questions such as: "What features are being used frequently?", "How do we prioritize between potential new features?" and "What elements of Netdata are most important to our users?"

By leaving anonymous telemetry enabled, users indirectly contribute to shaping Netdata's roadmap, providing invaluable information that helps us prioritize our efforts for the project and the community.

We are aware that for privacy or regulatory reasons, not all environments can allow telemetry. To cater to this, we have simplified the process of disabling telemetry:

- During installation, you can append `--disable-telemetry` to our `kickstart.sh` script, or
- Create the file `/etc/netdata/.opt-out-from-anonymous-statistics` and then restart Netdata.

These steps will disable the anonymous telemetry for your Netdata installation.

Please note, even with telemetry disabled, Netdata still requires a [Netdata Registry](https://learn.netdata.cloud/docs/configuring/securing-netdata-agents/registry) for alert notifications' Call To Action (CTA) functionality. When you click an alert notification, it redirects you to the Netdata Registry, which then directs your web browser to the specific Netdata Agent that issued the alert for further troubleshooting. The Netdata Registry learns the URLs of your agents when you visit their dashboards.

Any Netdata Agent can act as a Netdata Registry. Simply designate one Netdata Agent as your registry, and our global Netdata Registry will no longer be in use. For further information on this, please refer to [this guide](https://learn.netdata.cloud/docs/configuring/securing-netdata-agents/registry).

&nbsp;<br/>&nbsp;<br/>

Browse the [Netdata stargazers on GitHub](https://github.com/netdata/netdata/stargazers) to discover users from renowned companies and enterprises, such as AMD, Amazon, Baidu, Cisco, Delta, Facebook, IBM, Intel, Netflix, Qualcomm, Riot Games, SAP, Samsung, Unity, Valve, and many others.

Netdata also enjoys significant usage in academia, with notable institutions including New York University, Columbia University, New Jersey University, among several others.

And, Netdata is also used by numerous governmental organizations worldwide.

In a nutshell, Netdata proves invaluable for:

- **Infrastructure intensive organizations**<br/>
  Such as hosting/cloud providers and companies with hundreds or thousands of nodes, who require a high-resolution, real-time monitoring solution for a comprehensive view of all their components and applications.
  
- **Technology operators**<br/>
  Those in need of a standardized, comprehensive solution for round-the-clock operations. Netdata not only facilitates operational automation and provides controlled access for their operations engineers, but also enhances skill development over time.

- **Technology startups**<br/>
  Who seek a feature-rich monitoring solution from the get-go.

- **Freelancers**<br/>
  Who seek a simple, efficient and straightforward solution without sacrificing performance and outcomes.

- **Professional SysAdmins and DevOps**<br/>
  Who appreciate the fine details and understand the value of holistic monitoring from the ground up.

- **Everyone else**<br/>
  All of us, who are tired of the inefficiency in the monitoring industry and would love a refreshing change and a breath of fresh air. :slightly_smiling_face:

### :globe_with_meridians: Is Netdata open-source?

The Netdata Agent back-end is entirely open-source. We ship 3 different versions of the UI: 2 open-source versions and 1 closed-source version.

<details><summary>Click to see detailed answer ...</summary>
&nbsp;<br/>&nbsp;<br/>

The entire back-end of the Netdata Agent is open-source, licensed under GPLv3+. We don't develop a separate enterprise version. All users, including commercial ones, use the same Netdata Agent.

The Netdata Agent is shipped with multiple UI versions:

- `http://agent.ip:19999/v0/`, the original open-source single-node UI, GPLv3+.
- `http://agent.ip:19999/v1/`, the latest open-source single-node UI, GPLv3+.
- `http://agent.ip:19999/v2/`, a snapshot of the latest Netdata Cloud UI as it was at the time the agent was released, licensed to be distributed with Netdata Agents under [NCUL1](https://github.com/netdata/netdata/blob/master/web/gui/v2/LICENSE.md).

When you access a Netdata Agent via `http://agent.ip:19999/` a splash screen attempts to use the latest live version of Netdata Cloud UI (downloaded from Cloudflare). This only happens when the web browser has internet connectivity and Netdata Cloud is not disabled at the agent configuration. Otherwise, it falls back to `http://agent.ip:19999/v2/`.

The Netdata Cloud UI is not open-source. But we thought that it is to the benefit of the community to allow everyone to use it directly with Netdata Agents, for free, even if Netdata Cloud is not used.

## :pray: Contribute

Contributions are essential to the success of open-source projects. In other words, we need your help to keep Netdata great!

What is a contribution? All the following are highly valuable to Netdata:

1. **Let us know of the best-practices you believe should be standardized**<br/>
   Netdata should out-of-the-box detect as many infrastructure issues as possible. By sharing your knowledge and experiences, you help us build a monitoring solution that has baked into it all the best-practices about infrastructure monitoring.

2. **Let us know if Netdata is not perfect for your use case**<br/>
   We aim to support as many use cases as possible and your feedback can be invaluable. Open a GitHub issue, or start a GitHub discussion about it, to discuss how you want to use Netdata and what you need.

   Although we can't implement everything imaginable, we try to prioritize development on use-cases that are common to our community, are in the same direction we want Netdata to evolve and are aligned with our roadmap.

3. **Support other community members**<br/>
   Join our community on GitHub, Discord and Reddit. Generally, Netdata is relatively easy to set up and configure, but still people may need a little push in the right direction to use it effectively. Supporting other members is a great contribution by itself!

4. **Add or improve integrations you need**<br/>
   Integrations tend to be easier and simpler to develop. If you would like to contribute your code to Netdata, we suggest that you start with the integrations you need, which Netdata does not currently support.
