NAME

       fddist - file descriptor usage distributions. Uses DTrace.

SYNOPSIS

       fddist [-r|-w]

DESCRIPTION

       This  prints  distributions for read and write events by file descriptor, by process. This can be used to determine which file descriptor a
       process is doing the most I/O with.

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

OPTIONS

       -r     reads only

       -w     writes only

EXAMPLES

       Sample both read and write activity,
	      # fddist

       Sample reads only,
	      # fddist -r

FIELDS

       EXEC   process name

       PID    process ID

       value  file descriptor

       count  number of events

BASED ON

       /usr/demo/dtrace/lquantize.d

DOCUMENTATION

       DTrace Guide "Aggregations" chapter (docs.sun.com)

       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

       fddist will sample until Ctrl-C is hit.
