# What is Netdata?
|
|
|
|
Netdata helps sysadmins, SREs, DevOps engineers, and IT professionals collect all possible metrics from systems and
|
|
applications, visualize these metrics in real-time, and troubleshoot complex performance problems.
|
|
|
|
Netdata's solution uses two components, the Netdata Agent and Netdata Cloud, to deliver real-time performance and health
|
|
monitoring for both single nodes and entire infrastructure.
|
|
|
|
## 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](/docs/get-started.mdx) 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](https://www.netdata.cloud/blog/why-netdata-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.
|
|
|
|
|
|
|
|
## What you can do with Netdata
|
|
|
|
Netdata is designed to be both simple to use and flexible for every monitoring, visualization, and troubleshooting use
|
|
case:
|
|
|
|
- **Collect**: Netdata collects all available metrics from your system and applications with 300+ collectors,
|
|
Kubernetes service discovery, and in-depth container monitoring, all while using only 1% CPU and a few MB of RAM. It
|
|
even collects metrics from Windows machines.
|
|
- **Visualize**: The dashboard meaningfully presents charts to help you understand the relationships between your
|
|
hardware, operating system, running apps/services, and the rest of your infrastructure. Add nodes to Netdata Cloud
|
|
for a complete view of your infrastructure from a single pane of glass.
|
|
- **Monitor**: Netdata's health watchdog uses hundreds of preconfigured alarms to notify you via Slack, email,
|
|
PagerDuty and more when an anomaly strikes. Customize with dynamic thresholds, hysteresis, alarm templates, and
|
|
role-based notifications.
|
|
- **Troubleshoot**: 1s granularity helps you detect and analyze anomalies other monitoring platforms might have
|
|
missed. Interactive visualizations reduce your reliance on the console, and historical metrics help you trace issues
|
|
back to their root cause.
|
|
- **Store**: Netdata's efficient database engine efficiently stores per-second metrics for days, weeks, or even
|
|
months. Every distributed node stores metrics locally, simplifying deployment, slashing costs, and enriching
|
|
Netdata's interactive dashboards.
|
|
- **Export**: Integrate per-second metrics with other time-series databases like Graphite, Prometheus, InfluxDB,
|
|
TimescaleDB, and more with Netdata's interoperable and extensible core.
|
|
- **Stream**: Aggregate metrics from any number of distributed nodes in one place for in-depth analysis, including
|
|
ephemeral nodes in a Kubernetes cluster.
