sudo apt-get update
sudo apt-get upgrade -y

Future, down load the Netdata installer script with the command:


When the down load finishes, operate the installer with the command:

sudo sh

Wherever TOKEN is the personal token and ROOMS is the name of the space you produced when you signed up.

The moment you assert your server, you can be equipped to look at the Netdata dashboard from within just your Netdata account (so you can entry the server dashboard from outside the house your LAN).

If you really don’t want to go that route, merely don’t simply click the Signal In button and check each of your servers separately.
