Netdata is an open-source tool designed to collect real-time metrics on various aspects of your system, including CPU usage, disk activity, bandwidth usage, website visits, and more. It provides a comprehensive dashboard that allows you to monitor the health and performance of your Debian 12 system. In this tutorial, we will guide you through the process of installing and configuring Netdata on your Debian 12 server.

Step 1: Update the Debian 12 System

Before we begin, it’s important to ensure that your Debian 12 system is up to date. To download the newest versions of packages and their dependencies, open the terminal and run the following commands:

apt update
apt list --upgradable
apt upgrade

These commands will update the package lists, display the available upgrades, and install all the available packages and their versions.

Step 2: Downloading Netdata Package

Now that your system is up to date, you can proceed to download and install the Netdata package. To install Netdata, run the following command on your server:

apt install netdata -y

The -y flag is used for confirmation, which will automatically answer “yes” to any prompts from the installer.

Step 3: Netdata Configuration File

After installing Netdata, we need to make a small change in the configuration file to access the dashboard using your server’s IP address. Open the configuration file by entering the following command:

vi /etc/netdata/netdata.conf

Within the configuration file, you’ll find a section labeled [global]. In this section, there is a line that specifies the IP address to bind the Netdata socket to, which is set to 127.0.0.1 by default. To access the Netdata dashboard using your server’s IP address, replace 127.0.0.1 with your actual IP address. The modified configuration should look like this:

[global]
run as user = netdata
web files owner = root
web files group = root
# Netdata is not designed to be exposed to potentially hostile networks. See https://github.com/netdata/netdata/issues/164
bind socket to IP = <Enter your IP address here>

Save the file and exit the text editor.

Step 4: Restart Netdata Service

After modifying the configuration file, you need to restart the Netdata service for the changes to take effect. Run the following command in the terminal to restart Netdata:

systemctl restart netdata

Step 5: Firewall Configuration

If your firewall is enabled, you will need to allow access to the Netdata dashboard port. Use the following command to allow incoming connections on port 19999:

ufw allow 19999

Step 6: Accessing the Netdata Dashboard

With Netdata successfully installed and configured, you can now access the Netdata dashboard through your web browser. Open your browser and enter the following URL, replacing <IP_Address> with the actual IP address of your server:

http://<IP_Address>:19999/

You will be presented with the Netdata dashboard, which provides real-time metrics and visualizations of your system’s performance. Explore the various tabs and charts to gain insights into your server’s health and resource usage.

Conclusion

In this tutorial, you learned how to install and configure Netdata, an open-source monitoring tool, on your Debian 12 system. By following these steps, you can now effectively monitor the performance of your system and ensure optimal resource utilization. Netdata’s intuitive dashboard provides real-time metrics that empower you to make informed decisions about your server’s health and performance.
