Had an interesting conversation with an ex-coworker Rob Oikawa who now works in MSNBC.COM as an architect. We're both old timers for the industry who enjoy thinking out of the box.
After kicking around a bunch of ideas and discussing the Green topic, Rob hit upon a good observation. He said, "Dave you look for the truth as part of being Green."
2 a (1): the state of being the case : fact (2): the body of real things, events, and facts : actuality (3)often capitalized : a transcendent fundamental or spiritual reality b: a judgment, proposition, or idea that is true or accepted as true <truths of thermodynamics> c: the body of true statements and propositions
Simple observation. Makes sense.
A green technique is to look for the truth.
Why add the metering and monitoring to your systems? To look for the truth of performance and consumption.
