>Just something for folks to think on in regards to Solaris and what
statistics SE collects - the kstat command (which I think is nothing more
then a perl script) exists that displays a LARGE amount of data by grabbing
it from the - guess what ? - the /dev/kstat device.  Basically what SE does.

coding to make the stored output look like how SE does it.

The Sun Perl provides several modules that this script requires e.g. like a
module for reading stuff from the kstat device.  Considering SE is a
scripting language and the Sun provided Perl has a kstat module - most if
not all of what SE does can now be "scripted" using Perl.

You're close.  Sun implements kstat as a series of libraries available to C
(and hence to Perl).  The Perl kstat program is merely a convenience.  SE
uses the C libraries.  You can examine the kstat output by typing "netstat
-k".
