SUMMARY: load statistics under Solaris 2.x

This group never ceases to amaze me. I received many answers
with exactly the information I was looking for.

Since I was only looking for simple information like CPU loading
over time the best solution was to use sar. I needed to uncomment
the sa1 and sa2 lines in sys's crontab in order for the sar
data to be collected and recorded every 20 minutes. The sa1
script records the sar data and sa2 script creates a report
of that data weekly. The packages that contain sar are
SUNWacc and SUNWaccr.

Some people recomended using top or perfmeter, but I don't know how
to run perfmeter without actually being logged in and I don't know
how to turn on logging on top so I didn't try these ideas.

Other recomendations include proctool (available at and
some tools written by Adrian Cockcroft (info at

Ed Finch is writing a tool to graph the ouput of sar (this looks pretty
good). You can see it at

Original Post:

Hi all,

I have been put in a position to gather statistics for the loads
on all of our sparcs (all are 2.5.1 or 2.6). I am just starting
to look into this so I appologize for my ignorance on this matter.
I am guessing that the best thing to use is sar. Is this the best
way to go? Are there any cheap/freeware programs for gathering
this kind of information?

On a side note, I have noticed that some of our machines do not
have sar installed on them. Does anyone know what package
contains sar?

Thanks for your help!!
