I have published numerous articles on IBM.COM through a publication called CCR2. CCR2 was a second generation of the old "Candle Computer Report". CCR2 is now becoming the "IBM System z Advisor". Look for more relevant articles and information there.
I have added a few links to some of my prior work, including an article I wrote last year on the benefits of using OMEGAMON XE For Mainframe Networks to integrate network performance data into your overall monitoring strategy.
