Sometimes, when we use OpenSolaris, we will find out the memory usage is very high. That's because ZFS ARC architecture will use memory as possible, and how can we know the ZFS ARC status? Actually we can use the command "kstat", but it seems to hard for general end user. And I found out a good script from World Wide Web, Neelakanth Nadgir , who writes a script in perl for easy to check ZFS ARC. And this script is worth for you to read. regards, Stanley Huang ******************************************************************************** #!/bin/perl -w # # Print out ZFS ARC Statistics exported via kstat(1) # For a definition of fields, or usage, use arctstat.pl -v # # Author: Neelakanth Nadgir http://blogs.sun.com/realneel # Comments/Questions/Feedback to neel_sun.com or neel_gnu.org # # CDDL HEADER START # # The contents of this file are subject to the terms of the # Common Development and Distribution License, Version 1.0 only # (the "License"...
