Traffic Statistics in Linux

This bash script would help you to get the traffic flowed in different port.

Environment requirement

This bash script required iptables in your system.

If you are using Cent OS 7, before use this, please execute "yum install network-tools"

How to use

Before you use, please add execute premission :

chmod +x traffic_accounting.sh

---

If you wana to get the traffic flowed in port 80, you should start the traffic statistics with:

./traffic_accounting.sh add 80

After this command is executed, the system would start to collect the traffic statistics for port 80

You can add more if you want

The unit is byte

---

After, you can get the inbound traffic in byte unit by executing:

./traffic_accounting.sh get 80 in

You can get the outbound traffic in byte unit by executing:

./traffic_accounting.sh get 80 out

---

If you wana to reset for all ports' traffic statistics, you have to executing:

./traffic_accounting.sh clean

So sorry that there is no way to reset for a specific port. I am tring to do this
