z Processor Consumption Analysis (including z13), or What is Consuming All the CPU?
Project and Program: MVS
, MVS Performance
, SHARE in Orlando 2015
This session has been updated for the new z13 processors.
The first step to any processor analysis is to understand your processor configuration and settings. The second step is to understand what workloads, address spaces, and transactions are consuming the fixed processor resources. It is only after understanding what and how the processor is being consumed can you conduct any sort of processor tuning or optimization exercise.
During this presentation Peter Enrico will show you how to conduct a processor resource consumption analysis. You will be provided with a top down approach to better understand processor measurements available to help you gain insight into how the CPU resources are being consumed, and by what LPARs, workloads, and transactions. The presentation will show what is known as a drill down approach to processor performance analysis. Updates relative to the z13 processor will be included.-Peter Enrico-Enterprise Performance Strategies Inc.
