| Today the standard SMF interval is usually about 15 minutes. In the world of z, 15 minutes is an eternity. So much can happen, and a 15 minute average can hide important bursts of activity and events. This presentation will discuss the high frequency performance measurements of the SMF 98 and 99 records. These z/OS and WLM records assist during performance debugging and analysis. For example, the SMF 98 contain lock and resource usage measurements, and 99 records contain a wealth of information related to WLM algorithm decisions. Peter Enrico will provide an intro to the measurements of the SMF 98 and SMF 99 records, as well as show some very practical uses for these records and a number of performance insights these records will provide. |
Peter Enrico has strong and diverse experience with the IBM zArchitecture platforms, and a solid background in z/OS, Workload Manager, Parallel Sysplex, UNIX System Services, and WebSphere e-business performance. Peter also has extensive experience measuring, analyzing, and tuning z/OS systems, Sysplexes, and subsystems. Peter's abilities extend beyond just performance. He is considered a highly qualified and effective communicator and seminar instructor. He teaches on a wide array of topics including Workload Manager, WebSphere for z/OS, basic MVS performance, Parallel Sysplex, UNIX System Services, and much more. His classes include 'WLM Performance and Re-evaluation of Goals', 'Essential z/OS Performance Tuning', and his newest 'Parallel Sysplex Performance and Tuning’ class.
