Thanks for all the responses, the general consensus suggested using
gnuplot in conjuction with perl to produce the output

Michael --

I haven't seen anything from sar that output graphs, but Concord's
NetHealth provides graphic info on your network and, by extension,
your machines.

Check out sarcheck at www.sarcheck.com; they print out a text report
(which, at first glance, looks fairly detailed) and they pride
themselves on *not* just printing out graphs and letting you do the
analysis. Their code costs to license, but it looks interesting...

:-D

Have a look at http://scholar.nepean.uws.edu.au/cgi-bin/Sarplot
and see ifthat is what you mean.

It's not 100% complete yet (haven't got time at present),
but if it is what you want, I'll package it up for you and give you 
a restricted release.

Funny you should ask...I'm writing a perl script that I call sarge
("System Activity Reporter Graphing Engine") to do just that. I'm
basically using "man sar" and the O'Reilly book "System Performance
Tuning" and am graphing whatever looks useful. I've attached samples of
the available graphs for your reference. Sarge should be complete within
a week; I'll put the finished code at http://www.dc.net/efinch along
with some other goodies. The dimensions of the graphs are among the
configurable options.

Regards,
Ed

I know I'm a bit late, but such is the life of a Unix Admin as you
probably 
know.  I am about to implement the same thing.  What I'm going to do is 
manipulate various output files, one each for vmstat, mpstat, iostat,
sar, etc 
into a format such that the date and time are on the left side and the
values in 
quote delimited fields to the right.  Then my plan is to use GNUplot to
graph 
them, or even MS Excel.

Hope this is helpful.

Special thanks to Oddbjxrn Steffensen [oddbjorn@oddbjorn.bdc.no] who
included the following script:

I was in the same situation like you, peeked around, and didn't find
anything that really did what I wanted to. So -- I hacked together this
small script, which depends on gnuplot. This is _not_ very pretty, with
hardcoded paths and so on, but at least it works for me. Feel free to 
mangle it at will.
