I want to know is there any command-line tool (windows built-in or 3rd party), that can be used to check bandwidth utilization of a particular process or executable?

For example, i want to check the utilization of a particular program that i am developing over a period of time or may be i just want to detect when it starts utilizing bandwidth over a certain cut off limit that i define.

Reason why i need this, is because i use 3rd party libraries when are dependent on some online resources and i want to enable some functionality that can take appropriate action depending upon certain bandwidth usage if it is exceeding the required limit.

I'm not really sure whether there exists a program for this, but you could consider running your program in a virtual machine such that you can use any general network monitoring tool rather than an application specific monitoring tool.

Interesting, yes that would at least give me a rough idea of utilization, but i won't be able to take action programatically under certain bandwidth utilization. – Johnydep May 2 '12 at 13:27

Is there a particular reason why it has to be a "command-line tool"?

NetLimiter can do what you want, but is managed through a small GUI. It's available in free, cheap and a more expensive edition.

I just don't see anything in your specific requirements that says this couldn't be handled by a GUI program.

Command-Line because i want to handle everything through software and not through human iteration. if there are command line option, i can invoke external process and run those commands and read the output over output/error stream. with a GUI, you are very limited to the scale of an end user only. – Johnydep May 2 '12 at 13:29
