With Netdata, you get real-time, per-second updates. Clear **insights at a glance**, no complexity.

<details>
 <summary>All heroes have a great origin story. Click to discover ours.</summary>

In 2013, at the company where Costa Tsaousis was COO, a significant percentage of their cloud-based transactions failed silently, severely impacting business performance.

Costa and his team tried every troubleshooting tool available at the time. None could identify the root cause. As Costa later wrote:

“*I couldn’t believe that monitoring systems provide so few metrics and with such low resolution, scale so badly, and cost so much to run.*”

Frustrated, he decided to build his own monitoring tool, starting from scratch.

That decision led to countless late nights and weekends. It also sparked a fundamental shift in how infrastructure monitoring and troubleshooting are approached, both in method and in cost.

### Most Energy-Efficient Monitoring Tool

According to the [University of Amsterdam study](https://www.ivanomalavolta.com/files/papers/ICSOC_2023.pdf), Netdata is the most energy-efficient tool for monitoring Docker-based systems. The study also shows Netdata excels in CPU usage, RAM usage, and execution time compared to other monitoring solutions.

`email`, `Slack`, `Telegram`, `PagerDuty`, `Discord`, `Microsoft Teams`, and more.

> [!NOTE]  
> Email alerts work by default if there's a configured MTA.

### 4. Configure Parents

You can centralize dashboards, alerts, and storage with Netdata Parents:

* [Streaming Reference](https://learn.netdata.cloud/docs/streaming/streaming-configuration-reference)

> [!NOTE]

  classDef mainNode fill:#f0f0f0,stroke:#333,stroke-width:1px,color:#333
```

With each Agent you can:

1. **Collect** – Gather metrics from systems, containers, apps, logs, APIs, and synthetic checks.
2. **Store** – Save metrics to a high-efficiency, tiered time-series database.
3. **Learn** – Train ML models per metric using recent behavior.
4. **Detect** – Identify anomalies using trained ML models.
5. **Check** – Evaluate metrics against pre-set or custom alert rules.
6. **Stream** – Send metrics to Netdata Parents in real time.
7. **Archive** – Export metrics to Prometheus, InfluxDB, OpenTSDB, Graphite, and others.
8. **Query** – Access metrics via an API for dashboards or third-party tools.
9. **Score** – Use a scoring engine to find patterns and correlations across metrics.

## FAQ

<details>
<summary>Is Netdata secure?</summary>

Yes. Netdata follows [OpenSSF best practices](https://bestpractices.coreinfrastructure.org/en/projects/2231), has a security-first design, and is regularly audited by the community.

* [Security design](https://learn.netdata.cloud/docs/security-and-privacy-design)
* [Security policies and advisories](https://github.com/netdata/netdata/security)

</details>

<details>
<summary>Does Netdata use a lot of resources?</summary>

No. Even with ML and per-second metrics, Netdata uses minimal resources.

* \~5% CPU and 150MiB RAM by default on production systems
* <1% CPU and \~100MiB RAM when ML and alerts are disabled and using ephemeral storage
* Parents scale to millions of metrics per second with appropriate hardware

> You can use the **Netdata Monitoring** section in the dashboard to inspect its resource usage.

</details>

<details>
<summary>How much data retention is possible?</summary>

As much as your disk allows.

With Netdata you can use tiered retention:

* Tier 0: per-second resolution
* Tier 1: per-minute resolution
* Tier 2: per-hour resolution

These are queried automatically based on the zoom level.
</details>

<details>
<summary>Can Netdata scale to many servers?</summary>

Yes. With Netdata you can:

* Scale horizontally with many Agents
* Scale vertically with powerful Parents
* Scale infinitely via Netdata Cloud

> You can use Netdata Cloud to merge many independent infrastructures into one logical view.

</details>

<details>
<summary>Is disk I/O a concern?</summary>

No. Netdata minimizes disk usage:

* Metrics are flushed to disk every 17 minutes, spread out evenly
* Uses direct I/O and compression (ZSTD)
* Can run entirely in RAM or stream to a Parent

> You can use `alloc` or `ram` mode for no disk writes.

</details>

<details>
<summary>How is Netdata different from Prometheus + Grafana?</summary>

With Netdata you get a complete monitoring solution—not just tools.

* No manual setup or dashboards needed
* Built-in ML, alerts, dashboards, and correlations
* More efficient and easier to deploy

> [Performance comparison](https://blog.netdata.cloud/netdata-vs-prometheus-performance-analysis/)

</details>

<details>
<summary>How is Netdata different from commercial SaaS tools?</summary>

With Netdata you can store all metrics on your infrastructure—no sampling, no aggregation, no loss.

* High-resolution metrics by default
* ML per metric, not shared models
* Unlimited scalability without skyrocketing cost

</details>

<details>
<summary>Can Netdata run alongside Nagios, Zabbix, etc.?</summary>

Yes. You can use Netdata together with traditional tools.

With Netdata you get:

* Real-time, high-resolution monitoring
* Zero configuration and auto-generated dashboards
* Anomaly detection and advanced visualization

</details>

<details>
<summary>What if I feel overwhelmed?</summary>

You can start small:

* Use the dashboard's table of contents and search
* Explore anomaly scoring ("AR" toggle)
* Create custom dashboards in Netdata Cloud

> [Docs and guides](https://learn.netdata.cloud/guides)

</details>

<details>
<summary>Do I have to use Netdata Cloud?</summary>

No. Netdata Cloud is optional.

Netdata works without it, but with Cloud you can:

* Access remotely with SSO
* Save dashboard customizations
* Configure alerts centrally
* Collaborate with role-based access

</details>

<details>
<summary>What telemetry does Netdata collect?</summary>

Anonymous telemetry helps improve the product. You can disable it:

* Add `--disable-telemetry` to the installer, or
* Create `/etc/netdata/.opt-out-from-anonymous-statistics` and restart Netdata

> Telemetry helps us understand usage, not track users. No private data is collected.

</details>

<details>
<summary>Who uses Netdata?</summary>

You'll join users including:

* Major companies (Amazon, ABN AMRO Bank, Facebook, Google, IBM, Intel, Netflix, Samsung)
* Universities (NYU, Columbia, Seoul National, UCL)
