The easiest/best perf. monitoring scripts that I have used actually come with Solaris. Do a man on sar and sar(1m). (stands for System Activity Reporter) To enable the sar monitoring system, all you need to do is uncomment a few lines in the /etc/init.d/perf file, or setup a few cron jobs in the user sys's crontab file.

The enty I use in sys's crontab looks like this:
0,10,20,30,40,50 * * * * /usr/lib/sa/sa1

This basically makes the sadc command collect data to be used by sar every 10 minutes.

Ahhh... I should have read your whole message.

We use a combination of Big Brother

http://maclawran.ca/bb-dnld/

and the free version of Sun Management Center

http://www.sun.com/sunmanagementcenter/

(basic version) for the functions that you are talking about. They may be a little overkill for what you are trying to look at, but both are relatively easy to setup and free.

Big Brother, for example, is set up to page/email us when:
a box is bounced,
monitored file systems reach a capacity above 90% full,
Veritas / Disk Suite has an issue,
etc...
