Once Netdata is installed, you can proceed to the next step.

Configure Netdata

By default, Netdata default configuration file located at /etc/netdata/netdata.conf. Now, open the file and change the server loopback address to your server’s IP address.

sudo nano /etc/netdata/netdata.conf

Make the following changes:

[global]
        run as user = netdata
        web files owner = root
        web files group = root
        # Netdata is not designed to be exposed to potentially hostile
        # networks.See https://github.com/firehol/netdata/issues/164
        bind socket to IP = 192.168.0.234

Save and close the file, then restart Netdata service to apply the changes:

sudo systemctl restart netdata

You can check the status of Netdata with the following command:

sudo systemctl status netdata
