Netdata is a rising star in the field of real-time system metrics monitoring. Compared with other tools of the same kind, Netdata:

• Monitors and renders various system metrics in real time, such as CPU, memory, disk I/O, network traffic, system processes, Apache/Nginx status, MySQL status, Postfix message queue, and others.
• Runs on most Linux distributions.
• Is highly optimized to use minimal CPU, memory, and disk I/O.
• Provide stunning real-time metrics graphics in an intuitive web interface.

In this article, I will demonstrate how to install Netdata on a Vultr Debian 9 server instance.

Prerequisites

Before reading further, you should have deployed a Vultr Debian 9 server instance and logged in as a non-root user with sudo privileges.

Step 1: Update the system

For security purposes, update the system to the latest stable status:

sudo apt-get update && sudo apt-get upgrade

Step 2: Install dependencies

In order to install Netdata, you need to install the dependencies below:

sudo apt-get install zlib1g-dev uuid-dev libmnl-dev gcc make git autoconf autoconf-archive autogen automake pkg-config curl

Step 3: Install Netdata

Install Netdata with the official installation script:

cd ~
git clone https://github.com/firehol/netdata.git --depth=1
cd netdata
./netdata-installer.sh

During the installation process, Press ENTER to start the installation.

The Netdata daemon will start.

You can start, stop and get the status of the Netdata service by running the following commands:

sudo systemctl start netdata
sudo systemctl stop netdata
sudo systemctl status netdata

Step 4: Modify firewall rules

Before you can access Netdata's web interface, you need to modify firewall rules to allow traffic on port 19999, the default communication port of Netdata:

sudo firewall-cmd --permanent --zone=public --add-port=19999/tcp
sudo firewall-cmd --reload

Reload the firewall:

service firewalld restart

Step 5: View the monitoring interface

Confirm the installation by opening your web browser and visiting the monitoring interface of Netdata:

http://<your-Vultr-server-IP>:19999

To further configure Netdata, edit its configuration file:

sudo vi /etc/netdata/netdata.conf

You can also view the current configuration:

http://<your-Vultr-server-IP>:19999/netdata.conf

Uninstall and Update Netdata
