I am running a Perl script that does alot of recursive find and replaces on my Solaris Ultra 250 server. I really want to know what you all use to monitor system resources when you run a Perl script on a web server. Here are the unix commands I am using to check:

ps -afe  | grep myscriptname.pl

truss -p 2345    --> 2345 is my process number

vmstat 3

top

Please advise if all these are going to monitor my script and what specific numbers/columns I should be paying attention to? My script seems to be using about 90 to 95% of cpu.
