Subject Performance measurement scripting
Date Thu, 02 Nov 2000 20:11:22 GMT
Craig,

I have a bash shell script that (currently) drives Apache, sar, and sa on 
a RedHat6.1 system. I will doctor it a bit and post it tonight to see if 
there are suggestions about what to include, modify, leave out, so that 
it will span most Unix/Linux systems.
