Sun Storage 7000 Analytics Overview
This blog explores the basics of Analytics - a DTrace based toolkit used with the Sun Storage 7000 line of storage appliances.These analytics are based on DTrace, but essentially hide the DTrace complexity in a cloak of Ajax-based browser graphics. Through the GUI, a storage administrator can determine which clients are causing which files on the server to be "hot", or resource use-intensive. Also the administrator can see the latency of each request to the blocks of that file, or how many request of each protocol are being processed, or how many cache hits a file had.

LEARN ABOUT OSX

creatbyproc.d

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

NAME

       creatbyproc.d - snoop creat()s by process name. Uses DTrace.

SYNOPSIS

       creatbyproc.d

DESCRIPTION

       creatbyproc.d is a DTrace OneLiner to print file creations as it occurs, including the name of the process calling the open.

       This  matches  file  creates  from the creat() system call; not all file creation occurs in this way, sometimes it is through open() with a
       O_CREAT flag, this script will not monitor that activity.

       Docs/oneliners.txt and Docs/Examples/oneliners_examples.txt in the DTraceToolkit contain this as a oneliner that can be cut-n-paste to run.

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

EXAMPLES

       This prints process names and new pathnames until Ctrl-C is hit.
	      # creatbyproc.d

FIELDS

       CPU    The CPU that recieved the event

       ID     A DTrace probe ID for the event

       FUNCTION:NAME
	      The DTrace probe name for the event

       remaining fields
	      The first is the name of the process, the second is the 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

       creatbyproc.d will run forever until Ctrl-C is hit.
