Netdata is a tool to visualize and monitor metrics in real time, optimized to accumulate all types of data. It is also optimized to accumulate all types of data, such as CPU usage, disk activity, SQL queries, website visits, etc. The tool is designed to visualize the now in as much detail as possible, allowing the user to get an overview of what is happening and what has just happened in your system or application.

Netdata is very easy to use

For the server monitoring conception conceived by Netdata, it is vital that everything is monitorable. It also has the following attributes.

• Out of the box: netdata supports auto-detection for everything. It collects more than 5000 metrics automatically, with zero configuration
• Basically, it can monitor practically in real time and achieves this without sacrificing performance in its execution.
• It is highly customizable thanks to HTML.
• Extensible: Anything you can get a number for, can be given to netdata, using its Plugin API.
• Scalable: netdata scales out, your web browser is the central netdata connecting all your servers together

Install Netdata on Ubuntu 20.04 / Debian 10

One of the main advantages of Netdata is that we can install it using the official Ubuntu repositories. This, apart from being secure, will give us the necessary stability in this kind of procedure.

So, open a terminal or SSH session.

When you start it, it updates Ubuntu completely.

sudo apt update
sudo apt upgrade

Once the system is fully upgraded, you can install Netdata by running the following command:

sudo apt install netdata

Netdata is also managed as a system service, so you can use the systemctl command to start it, stop it, or check its status.

Netdata is now available from http://localhost:19999 but you may want to configure Nginx as a reverse proxy.

Configuring Nginx as reverse proxy for Netdata

First, install Nginx from the Ubuntu repositories.

sudo apt install nginx

Next, create a new configuration file for Netdata

sudo nano /etc/nginx/conf.d/netdata.conf

And add the following:

upstream backend {
# the Netdata server
server 127.0.0.1:19999;
keepalive 64;
}
server {
# nginx listens to this
listen 80;
# the virtual host name of this
server_name angtest.ga;

    location / {

    proxy_set_header X-Forwarded-Host $host;
    proxy_set_header X-Forwarded-Server $host;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_pass http://backend;
    proxy_http_version 1.1;   
       proxy_pass_request_headers on;
    proxy_set_header Connection "keep-alive";
    proxy_store off;
}
}

Replace server_name with the name of your server.

It is also a good idea to secure your Netdata installation by installing and adding certificates to enable HTTPS.

So, install Certbot.

sudo apt install certbot python3-certbot-nginx

And create the new certificate for your domain by running:

sudo certbot --nginx --agree-tos --redirect --hsts --staple-ocsp --email you@example.com -d your-domain

Replace the email and -d values with your own.

Finally, restart Nginx.

sudo systemctl restart nginx

Using Netdata

Now you can open netdata from your web browser by opening https://your-domain and you will see the dashboard.

After that, just check the options on the left side of the screen.

So, enjoy it.

Conclusion

About Netdata you can say that it’s amazing how easy it is to use. Also, the app is really an Out-The-Box application because you simply don’t have to configure anything extra, it’s just install and go

Simple, easy to use, powerful and open source

For the server monitoring conception conceived by Netdata, it is vital that everything is monitorable. It also has the following attributes.

• Out of the box: netdata supports auto-detection for everything. It collects more than 5000 metrics automatically, with zero configuration

Installation on GNU/LINUX systems

The fastest and most direct way to install it is through the official repositories:

For Debian and Ubuntu:

              sudo apt install netdata

For OpenSuse:

             sudo zypper in netdata

Gentoo:

             sudo emerge –ask netdata

Arch Linux:

             sudo pacman -S netdata

This installation method is ideal if you want to do it quickly and without problems, but does not guarantee to have the latest stable version.

In this tutorial, we will use Ubuntu 18.04 and install the latest stable version of netdata.

On your GitHub site we found a method to install the latest stable version thanks to the execution of a single line that we will write in the terminal.

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

It is important not to run the above command with sudo.

Then we’ll notice that it looks for the missing dependencies and installs them.

Then you will download the netdata script.

The next thing the script will do is build and install netdata.

Will finally send us a message saying that the process was successfully completed.

First use of Netdata

Before running netdata, we must enable it as a service:

             sudo systemctl start netdata

Netdata uses port 19999, so we must enable the use of that port in the firewall.

             sudo ufw allow 19999/tcp

Now we can access it from the web:

              http:IP_SERVER:19999

About Netdata you can say that it’s amazing how easy it is to use. It’s really an Out-The-Box application because you simply don’t have to configure anything extra, it’s just install and go.

As against we can say that it would be better if the graphs showed them in a more orderly way and by categories.
