Installing Netdata on Debian 9

Netdata is a distributed, real-time performance and health monitoring system. This guide demonstrates how to install Netdata on a Vultr Debian 9 server instance.

Prerequisites

Before proceeding with this guide, make sure:

• You have a freshly deployed Debian 9 server instance.

• The software packages are up-to-date.

• You are connected via SSH as a non-root user with sudo privileges.

The IP address 192.0.2.123 is an example.

1. 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

2. Install Netdata

Install Netdata with the official installation script:

1. Make sure you run bash for your shell

   $ bash
   

2. Install Netdata directly from GitHub source

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

3. If no errors occur during 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
   

3. 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

4. View the Monitoring Interface

Confirm the installation by opening your web browser and visiting the monitoring interface of Netdata: http://192.0.2.123:19999

To further configure Netdata, edit its configuration file:

$ sudo vi /etc/netdata/netdata.conf
