Tutorial: Service component performance monitoring

This tutorial will guide you through an example of how to set up service component event monitors that are published to the Performance Monitoring Infrastructure (PMI), and how to view the resulting performance statistics on the Tivoli® Performance Viewer (TPV). This exercise will demonstrate how performance monitoring of service component event points differs from monitoring using the Common Event Infrastructure (CEI) server and loggers. The major difference that you will notice is that you select an entire service component element for performance monitoring, instead of individual events with specific natures. Because WebSphere® Process Server can monitor performance only on service component elements having events with ENTRY, EXIT, and FAILURE natures, you will have only those kinds of service component elements available to you to select for monitoring.

While the service component event points ENTRY, EXIT, and FAILURE are identical for all monitoring types, the process server performance monitoring function fires "minimized" events that do not contain all of the information encompassed in CEI events. These events are sent to the PMI, which calculates these performance statistics from corresponding sets of events: The PMI publishes the statistics to the TPV, which presents cumulative counters for the number of successful and failed invocations and a running average of the completion response times.

Objectives of this tutorial

After completing this tutorial you will be able to:
  • Select the performance statistics of service component elements that you wish to monitor.
  • View and interpret the resulting performance statistics.

Time required to complete this tutorial

This tutorial requires approximately 15-20 minutes to complete.

Prerequisites

In order to perform this tutorial, you must have:
  • Configured and started a process server.
  • Enabled the PMI on the process server.
  • Installed and started the Samples Gallery application on the process server.
  • Installed and started the business rules sample application on the process server. Follow the instructions on the Samples Gallery page to set up and run the business rules sample application.
After all of these prerequisites have been completed, run the business rules sample application from the Samples Gallery at least once before proceeding with the tutorial.
