iofileb.d

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

NAME

       iofileb.d - I/O bytes by file and process. Uses DTrace.

SYNOPSIS

       iofileb.d

DESCRIPTION

       This  prints  a	summary  of  requested	disk  activity	by pathname, providing totals of the I/O events in bytes. It is a companion to the
       iofile.d script - which prints in terms of I/O wait time, not bytes.  I/O wait time  is	a  better  metric  for	understanding  performance
       issues.	Both disk and NFS I/O are measured.

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

EXAMPLES

       Sample until Ctrl-C is hit then print report,
	      # iofileb.d

FIELDS

       PID    process ID

       CMD    process name

       KB     kilobytes of disk I/O

       FILE   file pathname

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

       iofileb.d will sample until Ctrl-C is hit.

SEE ALSO

       iofile.d(1M), iosnoop(1M), dtrace(1M)
