rwbypid.d(1m)							   USER COMMANDS						     rwbypid.d(1m)

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 directory. 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.
