Installing Netdata on Debian 11

Installing Netdata on Debian 11

Since Netdata has been included in the official Debian repositories, we don’t have to do much to install it. In other words, we don’t have to add repositories or anything similar to that.
So, open an SSH connection to your server and update it.

Code:

sudo apt update


sudo apt upgrade

After that, run the following command to install Netdata on Debian 11.
sudo apt install netdata
This will simply install Netdata.

Working with the Netdata service

The installation of Netdata also includes the installation of a service with which we can manage the Netdata execution.
So, to start it you have to execute
sudo systemctl start netdata
It is also advisable to leave it enabled to start with the system
sudo systemctl enable netdata
To check if the service and therefore the program is running, you can use the following command
sudo systemctl status netdata
If we get an output similar to this, then we can be sure that the program is running properly.
1.- Netdata service status
If you want to stop the program then run
sudo systemctl stop netdata
Then you can with the help of the

Code:

systemctl

command manage the operation of Netdata.

Configure Netdata to be accessible from any host

The Netdata configuration file is

Code:

/etc/netdata/netdata.conf

and inside it, we have a value to modify.
So, make a backup of this before using it.

Code:

sudo cp /etc/netdata/netdata.conf /etc/netdata/netdata.conf.bak

And now if you edit it

Code:

sudo nano /etc/netdata/netdata.conf

The value you have to modify is

Code:

bind socket to IP

to which you have to assign the IP address of the server where you are running it.

Code:

bind socket to IP = X.X.X.X.X.X

Save the changes and close the editor.
Apply the changes by restarting the service
sudo systemctl restart netdata

Setting the Firewall before using it

Now we have to add a rule in the Firewall to make Netdata accessible. In short, we have to open port

Code:

19999

of the TCP protocol for this.
So, run

Code:

sudo ufw allow 19999/tcp

Apply the changes by running

Code:

sudo ufw reload
