Read/write bytes by vnode type. uses dtrace.
Usage
rwbytype.d
Overview
This program identifies the vnode type of read/write activity - whether that is for regular files, sockets, character special devices, etc. This is measuring at the application level, so file activity may well be cached by the system.
Since this uses DTrace, only users with root privileges can run this command.
Examples
