Finding the Edge of Surprise by Rich Olcott

I have definitely overlooked the following very good article of my CMG and IBM acquaintance:

MeasureIT - Issue 5.03 - Finding the Edge of Surprise by Rich Olcott 

At the 1st glance that article has a good overview of Classical SPC with some original suggestion how to apply that to IT data. Also I like the name of the article which could be a good short and metaphoric description of the main topic of this entire blog! 

BTW He provided there the reference to my CMG'2004 paper: “Mainframe Global and Workload Levels – Statistical Exception Detection System, Based on MASF,” CMG Proceedings (2004). The link to that my paper is published on very 1st posting of this blog!

And I have already mentioned  his previous work at my other posting: 
Aug 13, 2007
Dials for a PM Dashboard: Velocity's Missing Twin, and Quantifying Surprise, Rich Olcott
I plan to reread both his works and to add more comments-thoughts....

SEDS-Lite: Using Open Source Tools (R, BIRT and MySQL) to Report and Analyze Performance Data

Last Thursday we had a very good Southern Computer Measurement Group meeting of 16 attendees in Richmond VA, where I have presented the material about how to use R, BIRT, MySQL and EXCEL to analyze and report systems' performance data having as an example some real Unix server CPU utilization data for control charting.

Agenda is still on SCMG website and now my presentation slides are published and linked there:
