/*
* tcptop: display top TCP network packets by process.
* Written using DTrace tcp Provider.
*
* Usage: dtrace -s tcptop.d [count] [interval]
*
* This analyses TCP network packets and prints the responsible PID plus
* standard details such as IP address and port. This captures traffic
* of newly created TCP connections that were established while this program
* was running along with traffic from existing connections. It can help
* identify which processes is causing TCP traffic.
