Commands for internet measure

[Aquacooolingmac]

Could you come with suggestions for a command that would measure internet usage in percent, and a command that would measure how much data is flowing in kb. I would like, if both commands output in numbers only, so i can say 

 

var flow = NSAppleScript(source: "[script here]")!.executeAndReturnError(nil) = (2.453)

var percent = NSAppleScript(source: "[script here]")!.executeAndReturnError(nil) = (43.64)

...what? You can't measure an internet connection in percentage because speeds frequently change... and command for what? Linux/bash? Java? C++/C#? Python?

Are you looking for data for just your local computer, or for the whole network? If for the whole network, you should use SNMP to get the traffic levels of the WAN port. To use SNMP, you either need a router that supports it out of the box (may need to be enabled) or one that can be flashed with a firmware like DDWRT or Tomato.
