Hi Dave - tried to find a way to contact you outside of this, but have been unsuccessful to date - apologies all around if I'm using the wrong communication channel...
Your post confirmed some hunch I've had for a while - I've been trying to figure out a way to measure CPU, I/O, RAM and other resources on our web servers to get reasonable application benchmarking data - I've been told it's next to impossible, and I've had the hardest time finding any info on this type of benchmarking on the net (beyond gutfeelings, and vmstat and top - which only provide performance snapshots). Yet, I'm a strong believer that "you can't manage something you don't measure" (quoted from somewhere...), and you seem to have found concrete ways to do just that. Any chance you could share some of your references or resources on this server/app benchmarking stuff? I'd be much grateful for any insight.
