Welcome to Netdata! We're glad you're interested in our health monitoring and performance troubleshooting system.
Because Netdata is entirely open-source software, you can use it free of charge, whether you want to monitor one or ten thousand systems! All our code is hosted on GitHub.
This guide is designed to help you understand what Netdata is, what it's capable of, and how it'll help you make faster and more informed decisions about the health and performance of your systems and applications. If you're completely new to Netdata, or have never tried health monitoring/performance troubleshooting systems before, this guide is perfect for you.
If you have monitoring experience, or would rather get straight into configuring Netdata to your needs, you can jump straight into code and configurations with our getting started guide.
This guide contains instructions for Netdata installed on a Linux system. Many of the instructions will work on other supported operating systems, like FreeBSD and macOS, but we can't make any guarantees.
Where to go if you need help
No matter where you are in this Netdata guide, if you need help, head over to our GitHub repository. That's where we collect questions from users, help fix their bugs, and point people toward documentation that explains what they're having trouble with.
Click on the issues tab to see all the conversations we're having with Netdata users. Use the search bar to find previously-written advice for your specific problem, and if you don't see any results, hit the New issue button to send us a question.
Before we get started
Let's make sure you have Netdata installed on your system!
If you already installed Netdata, feel free to skip to Step 1: Netdata's building blocks.
The easiest way to install Netdata on a Linux system is our
kickstart.sh one-line installer. Run this on your system
and let it take care of the rest.
This script will install Netdata from source, keep it up to date with nightly releases, connects to the Netdata registry, and sends anonymous statistics about how you use Netdata. We use this information to better understand how we can improve the Netdata experience for all our users.
To install Netdata, run the following as your normal user:
wget -O /tmp/netdata-kickstart.sh https://my-netdata.io/kickstart.sh && sh /tmp/netdata-kickstart.sh
Or, if you have cURL but not wget (such as on macOS):
curl https://my-netdata.io/kickstart.sh > /tmp/netdata-kickstart.sh && sh /tmp/netdata-kickstart.sh
Once finished, you'll have Netdata installed, and you'll be set up to get nightly updates to get the latest features, improvements, and bugfixes.
If this method doesn't work for you, or you want to use a different process, visit our installation documentation for details.
In this introductory step, we'll talk about the fundamental ideas, philosophies, and UX decisions behind Netdata.
Visit Netdata's dashboard to explore, manipulate charts, and check out alarms. Get your first taste of visual anomaly detection.
While the dashboard lets you quickly move from one agent to another, Netdata Cloud is our SaaS solution for monitoring the health of many systems. We'll cover its features and the benefits of using Netdata Cloud on top of the dashboard.
While Netdata can monitor thousands of metrics in real-time without any configuration, you may want to tweak some settings based on your system's resources.
Learn how to tune, silence, and write custom alarms. Then enable notifications so you never miss a change in health status or performance anomaly.
Learn how to enable/disable collection plugins and configure a collection plugin job to add more charts to your Netdata dashboard and begin monitoring more apps and services, like MySQL, Nginx, MongoDB, and hundreds more.
Now that you configured your Netdata monitoring agent to your exact needs, you'll dive back into metrics snapshots, updates, and the dashboard's settings.
By default, Netdata can store lots of real-time metrics, but you can also tweak our custom database engine to your heart's content. Want to take your Netdata metrics elsewhere? We're happy to help you archive data to Prometheus, MongoDB, TimescaleDB, and others.
Run Netdata behind an Nginx proxy to improve performance, and enable TLS/HTTPS for better security.
