Control charts as a memory performance measurement tool (abstract only)

The needed data to analyze the utilization of the memory can be obtained from special hardware monitor devices or from software monitor programs. The software monitor programs such as IBM's RMF. Candle Corporation's OMEGAMON and Boole and Babbage's CPE are not as accurate as the hardware monitor devices (specially in the area of timing.) but solved all of the problems related to hardware monitors. Therefore the problem to analyze the utilization of the main memory is no longer getting the needed data. However, the presentation of the data in a format which is usable and comprehendible by both the system department (for tuning) and the data center management (for decision making) is a problem. This paper shows that the control chart technique developed by Shewart can be used as a measurement tool to analyze the utilization of the main memory to overcome data presentation problems.
