Monitor performance with Tivoli Performance Viewer

Tivoli Performance Viewer (formerly known as Resource Analyzer) is a stand-alone Java performance monitoring client for WebSphere Application Server. Use Tivoli Performance Viewer to retrieve performance data from application servers. The application servers collect data continuously, and Tivoli Performance Viewer retrieves the data as needed.

Tivoli Performance Viewer provides access to performance data for two kinds of resources:

• Application resources, such as enterprise beans and servlets
• WebSphere Application Server run-time resources, such as Java^(TM) virtual machine (JVM) memory, application server thread pools, and database connection pools

Performance data includes simple counters, statistical data (such as the response time for each method invocation of an enterprise bean), and load data (such as the average size of a database connection pool during a specified time interval). This data is reported for individual resources and for multiple resources.

Use Tivoli Performance Viewer to perform these tasks:

• View data in real time or view historical data from log files.
• View data in chart form, allowing comparisons of one or more statistical values for a given resource on the same chart. You can also specify different units of measurement to enable meaningful graphic displays.
• Record current performance data in a log and replay performance data from previous sessions.
• Compare data for a single resource to a group of resources on a single node.

Install Tivoli Performance Viewer from the WebSphere Application Server workstation CD-ROM for your workstation platform. For more information, see Install the workstation tools for WebSphere Application Server in Installation.
