Found my slide with SETDS #ControlChart at the #ICST conference... taken from my and Lin Merritt CMG 2003 paper

The following deck published in SlideShare

Using Control Charts for Detecting and Understanding Performance Regressions in Large Software

has the slide:

That was taken from my  CMG 2003 conference paper:

Disk Subsystem Capacity Management, Based on Business Drivers, I/O Performance Metrics and MASF


Interesting that S+ and S- I call now  EV+ and EV- , which are Exception Values to estimate the severity of the anomalies (exceptions). 

The sad fact is Lin Merritt my co-author of this paper has passed away a few days a ago - RIP
