Installation of Netdata on Linux to monitor server

Open the command terminal and simply paste the given script to install NetData on your Linux such as Ubuntu 20.04, CentOS 7/8, and others… You can also use it for Windows 10 WSL.

bash <(curl -Ss https://my-netdata.io/kickstart.sh)

It will ask your permission to download and install packages, so allow that and once the installation is completed, open a browser on your local or remote system that can access the Server or Desktop where Netdata has been installed.

In the URL bar type the server-IP-address along with port number 19999. For example, our IP address of the server was 192.168.189.163, thus to access Netdata Dashboard, the URL will be like this – https://192.168.189.163:19999 or http://127.0.0.1:19999 (only for the same system where you have netdata).

Dashboard

You will have the Dashboard of Netdata, there is no need to set up it any further, it will show all the information it can extract from the system right on the web-based Dashboard in your browser. To view the consumption of various resources individually, the user can jump directly to the individual overviews via the sidebar.

You can move the graphs using drag & drop, or you can enlarge sections by holding down the shift key. On smartphones and tablets, small screens Pinch & Zoom gestures work for a close view of generated data.

Closing thoughts:

Netdata is a very compact designed monitoring system that is available in both free and paid plains. Moreover, the user can go for Netdata cloud to centralized all system monitoring by simply installing its agent on all the nodes that need to be monitored. Overall, this platform is really well thought out and very well easy to implement without the need for root users. As there is no need to set up a web server, databases, or any configurations,  Netdata is once a setup and forget solution for system monitoring.
