First, we need to download NLoad. We can do this with the following command:
(APT)

apt-get install nload -y

Yum)

yum install nload -y

After downloading NLoad, we type ifconfig into our terminal and get our IP address in the inet section.
Sample output:

root@88:~# ifconfig
docker0: flags=4099 mtu 1500 inet 172.17.0.1 netmask 255.255.0.0 broadcast 172.17.255.255 ether 02:42:c9:75:3d:c9 txqueuelen 0 (Ethernet) RX packets 0 bytes 0 (0.0 B) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 0 bytes 0 (0.0 B) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
ens160: flags=4163 mtu 1500 inet 88.209.248.121 netmask 255.255.255.0 broadcast 88.209.248.255 inet6 fe80::250:56ff:febf:1a62 prefixlen 64 scopeid 0x20 ether 00:50:56:bf:1a:62 txqueuelen 1000 (Ethernet) RX packets 464003050 bytes 45762349064 (45.7 GB) RX errors 0 dropped 19848 overruns 0 frame 0 TX packets 192051603 bytes 117577614791 (117.5 GB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0

In the sample output, ens160 contains our IP address. We will use this for NLoad.

Example to Use Nload:

nload ens160

After typing this the output is:

If you did everything correctly, you can now watch your live traffic!
