I can’t say if it means pi symbol / number, or if it denotes the previous name for this technology, for example “Process Inteligence”. PI is too close to the more common BI to just be a coincidence.

Note. There are Channel9 videos demonstrating how MS uses OSIsoft to monitor certain operations. C9 video links are located on the CEP "SQL 2008 R2" pages. The SQL CEP functions are called StreamInsight.
