WLM - Using SMF 98 and 99 High Frequency Performance Measurements

(PM)

Stream: Woodcote
Time: 10:15 - 11:15


Presentation

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.
