This IBM Redbooks publication discusses Performance Toolkit for VM, a performance monitoring and analysis tool for z/VM. Derived from the earlier FCON/ESA product, Performance Toolkit for VM enables system administrators to collect and analyze VM performance data. Both real-time and history data can be processed by Performance Toolkit for VM, and it provides most of the functions that are available in Real Time Monitor (RTM) and Performance Reporting Facility (PRF).

In this book, we present an overview of the functions and features of Performance Toolkit for VM. We show how to navigate through its major monitoring screens and configure it. We also describe configuration for monitoring remote z/VM systems. Using examples, we illustrate how to monitor your z/VM system to identify potential performance problems. Major performance factors for running Linux guests under z/VM are discussed.
