9cd928fe5e3ea4e05f64cfb380beb54b2623e7dcAlan Maguire * udptop: display top UDP network packets by process.
9cd928fe5e3ea4e05f64cfb380beb54b2623e7dcAlan Maguire * Written using DTrace udp Provider.
9cd928fe5e3ea4e05f64cfb380beb54b2623e7dcAlan Maguire * Usage: dtrace -s udptop.d [count] [interval]
9cd928fe5e3ea4e05f64cfb380beb54b2623e7dcAlan Maguire * This analyses UDP network packets and prints the responsible PID plus
9cd928fe5e3ea4e05f64cfb380beb54b2623e7dcAlan Maguire * standard details such as IP address and port. This captures traffic
9cd928fe5e3ea4e05f64cfb380beb54b2623e7dcAlan Maguire * of newly created UDP connections that were established while this program
9cd928fe5e3ea4e05f64cfb380beb54b2623e7dcAlan Maguire * was running along with traffic from existing connections. It can help
9cd928fe5e3ea4e05f64cfb380beb54b2623e7dcAlan Maguire * identify which processes is causing UDP traffic.
