Netdata configuration file

---

We need to make a small change in the configuration file.

Open the configuration file by entering the following command.

vi /etc/netdata/netdata.conf 

The configuration file will look like this,

[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/netdata/netdata/issues/164
        bind socket to IP = 127.0.0.1

By default, the bind socket to IP is set to 127.0.0.1. To access the dashboard using the IP address, you need to replace the 127.0.0.1 with your server IP address.

[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/netdata/netdata/issues/164
        bind socket to IP = <Enter your IP address here>

Now save the file and restart the Netdata Service using the following command.

systemctl restart netdata

If the firewall is enabled, then allow the port using the following command.

Netdata Dashboard

---

Enter the following URL on the browser to access the Netdata dashboard. By default, netdata works on 19999 port.

http://<IP_Address>:19999/
