as you just noticed - you have one poll of data with ps
through /proc and another with /prstat -t .....
why not whack one set of them....
Ein popen! Ein DataTree! Ein InsertionPointForUpdate!!!
one way of doing this would be to modify my basic psTree
grovellor to take in what you are looking for....
http://www.wetware.com/drieux/pbl/Sys/psTree.txt
or maybe you modify your $ps cmd a little, and git rid
of this meshugenna prstat such like it is portable with
what and will not run into the gnu printer status code
by the same name???
I still say it wouldn't hurt you to open it up and find
out how simple grovelling the process table really is, or
maybe better yet, you finally just get silly and pull down
say
http://search.cpan.org/search?module=Solaris::Procfs
and see what you can do to upgrade it some....
Trust me - it's only a solaris box - it's not like you
have to get howard's multi-cpu variant for Crays - now that
was mensch molly wonking code to grovellate through....
