Nice Tool for Monitor Network

Nice Tool for Monitor Network

I just did that on CentOS machine.

>sudo yum install -y nload

Using nload
>nload venet0 -u b|k|m|g
b = bytes
k = kilobytes
m= megabytes
g = gigabytes

Or Iftop on CentOS works as well.
>sudo yum install iftop
>sudo iftop

On my Ubuntu System
>sudo apt-get install iftop
>sudo iftop

Here is some information about iftop
TX sending
RX receiving
total: sending + receiving
Peak:
rate: average speed of 2s, 10s, 40s
cum: since it starts
