Monitor systems and Docker deployments

Welcome to Netdata, software for distributed real-time performance and health monitoring of UNIX machines. Don’t you dare turn that page! A key advantage of Netdata is that it collects all of its metrics without introducing too much load on to the Linux machine that it runs on. In fact, most of the times you’ll forget that Netdata is running on a Linux machine – it’s only after you look at its impressive visualisations that you’ll remember the software is collecting, processing and visualising all these metrics! Another Netdata advantage is that it carries out real-time monitoring, so you can see what’s happening on the Linux machine at that time.

Install Netdata using your package manager. On a Debian or Ubuntu Linux system you can install Netdata by executing apt install netdata . The configuration directory of Netdata is /etc/netdata, but you’ll also find plenty of useful files inside /usr/lib/netdata. By default, Netdata listens to http://localhost:19999, which is the first thing that you should try, to ensure that the Netdata installation was successful.

The screenshot (right) shows the initial default screen, which is full of information. If you’re running Netdata on your own Linux machine, take the time to look at the Netdata visualisations. If you want to make Netdata available over your local network or the Internet, then you
