Measurements and Tools weinvestigated:Top• Load average: Our “traditional” measure of stress. The loadaverage is maintained by the kernel. It is defined as anaverage of the number of processes running and ready to run,as sampled over the previous one-minute interval of systemoperation.• Did not meet the need of large systems• Did not represent the depth of resource utilization on a systemOpenView Tools: Glance+ Pack, MeasureWare,Vantage Point Performance Agent, PerfViewSARAccountingHome Grown toolsMarch 2004 Copyright © 2004 HP corporate presentation.
