Abstract: WebSphere Application Server for z/OS takes advantage of SMF on z/OS to write informational records about the request activity taking place in the application server. The record written is a Type 120 subtype 9. IBM provides a sample Java-based "browser" capable of reviewing the 120.9 records produced. This browser is designed to accept "plugins" which may filter and display the information in different ways.
In this document David Follis of WAS z/OS development (and architect of the SMF 120.9 record) explores some useful SMF 120.9 Browser Plugins and what information they can yield from SMF 120.9 records. The plugins discussed are supplied as well.
