NAME
       rwbypid.d - read/write calls by PID. Uses DTrace.

SYNOPSIS
       rwbypid.d

DESCRIPTION
       This  script tracks the number of reads and writes at the syscall level
       by processes, printing the totals in a report. This matches  reads  and
       writes whether they succeed or not.

       Since  this  uses  DTrace, only users with root privileges can run this
       command.

EXAMPLES
       This samples until Ctrl-C is hit.
	      # rwbypid.d

FIELDS
       PID    process ID

       CMD    process name

       DIR    direction, Read or Write

       COUNT  total calls

DOCUMENTATION
       See the DTraceToolkit for further documentation under the  Docs	direc‐
       tory. The DTraceToolkit docs may include full worked examples with ver‐
       bose descriptions explaining the output.

EXIT
       rwbypid.d will sample until Ctrl-C is hit.
