Overview

Threshold monitor requests are used to initiate an observation on job-steps that exceed a user-defined threshold. You can create the threshold monitor request by using the TNEW command, which specifies the criteria that Application Performance Analyzer uses to initiate the observation. You can set up a single-step threshold monitor request to initiate an observation for a single job-step. You can also set up a multi-step threshold monitor request to initiate an observation for all steps in a job that exceed the criteria. The same criteria are used for all job steps.

Threshold monitor requests can be used to trigger the measurement of another job by entering the Trigger (TR) command on the threshold measurement. In this case, when the threshold criteria are exceeded for a single job-step, Application Performance Analyzer also begins executing the trigger request. In the case of a multi-step threshold request, only the first step that exceeds the threshold criteria initiates the trigger request.

Threshold monitor requests cannot be created for measuring specific DB2 Stored Procedures and IMS multiple address space measurements.

It is important that you are already familiar with the preceding information in this chapter before you use the threshold monitor feature. The threshold monitor request process uses most of the panels that are described in the previous sections, and the information is not repeated here.
