I am currently writing a program in Linux which needs to tell whether a specific process is network I/O intensive  or not at runtime. I have tried some tools such as iotop and iftop, but none of them can monitor a specific process. So, are there any ways to tell whether a process is network I/O intensive or not in user level? Any help would be greatly appreciated!
