Introduction and Using High Frequency SMF 98 and 99 Measurements

, SHARE Phoenix 2019
The new SMF 98 record provides all sorts of new performance measurements not previously provided by IBM. In addition, this new record is a high frequency record. After all, most RMF and CMF measurement intervals are 15 minutes, but a lot can happen in that 15 minutes. The SMF 98 record breaks down many measurements into intervals a few seconds long. They provide insight into utilizations, latent demand, locking, and other areas that influence performance.
During this presentation, Peter Enrico will provide an introduction to the SMF 98 records, as well as show some very practical uses and a number of performance insights that these records provide. Peter will also discuss some SMF 99 measurements as well. This session will be full of education, hints, and tips.-Peter Enrico-Enterprise Performance Strategies Inc.
