Real-time performance monitoring, done right! https://www.netdata.cloud
Netdata is high-fidelity infrastructure monitoring and troubleshooting.
Open-source, free, preconfigured, opinionated, and always real-time.
){kind=icon}
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...

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
errorandaccesslogs. - 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.
- 20+ notification platforms: Netdata's health watchdog sends warning and critical alarms to your favorite platform 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 for best-in-class interoperability.
💡 Want to leverage the monitoring power of Netdata across entire infrastructure? View metrics from any number of distributed nodes in a single interface and unlock even more features with Netdata Cloud.
Get Netdata
To install Netdata from source on most Linux systems (physical, virtual, container, IoT, edge), run our one-line installation script. This script downloads and builds all dependencies, including those required to connect to Netdata Cloud if you choose, and enables automatic nightly updates and anonymous statistics.
wget -O /tmp/netdata-kickstart.sh https://my-netdata.io/kickstart.sh && sh /tmp/netdata-kickstart.shTo view the Netdata dashboard, navigate to http://localhost:19999, or http://NODE:19999.
Other operating systems
See our documentation for additional operating systems, including Kubernetes, .deb/.rpm packages, and more.
Post-installation
When you're finished with installation, check out our single-node or infrastructure monitoring quickstart guides based on your use case.
Or, skip straight to configuring the Netdata Agent.
Read through Netdata's documentation, which is structured based on actions and 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 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.
