rwbbypid.d - read/write bytes by PID. Uses DTrace. rwbbypid.d This script tracks the bytes read and written at the syscall level by processes, printing the totals in a report. This is tracking the successful number of bytes read or written. Since this uses DTrace, only the root user or users with the dtrace_kernel privilege can run this command. Solaris stable - needs the sysinfo provider.

This samples until Ctrl-C is hit. # rwbbypid.d
