Logging performance data with TPV

The Tivoli Performance Viewer (TPV) provides an easy way to store real-time data for system resources, WebSphere Application Server pools and queues, and applications in log files for later retrieval. You can start and stop logging while viewing current activity for a server, and later replay this data. Logging of performance data captures performance data in windows of time so you can later analyze the data.

Before you begin

This article assumes that one or more servers have been created and are running on the node, and that you have configured the TPV log settings. The log settings may affect performance and are described in detail in Viewing Data with the Tivoli Performance Viewer. The TPV logging feature is not intended to be a full-time monitoring solution, but instead for selective data recording for subsequent replay and analysis.

About this task

You can study the sequence of events that led to a peculiar condition in the application server.

First, enable TPV logging so performance data generated in the application server persists in a log file stored at a specific location. Later, using the replay feature in TPV, view the performance data that was generated in exactly the same chronological order as it was generated in real time, enabling you to analyze a prior sequence of events.

You do not need to know the syntax and format in which log files are generated and stored. Do not edit log files generated by TPV; doing so will irrecoverably corrupt or destroy the performance data stored in the log files.

You can create and view logs in the administrative console.

Note: Performance degradation can occur when you use the Mozilla Firefox browser and Tivoli Performance Viewer to monitor the Application Server. Additionally, a memory leak problem occurs when you use Tivoli Performance Viewer for an extended period of time with the Mozilla Firefox browser.

Use Microsoft® Internet Explorer with Tivoli Performance Viewer to monitor the Application Server. To use Internet Explorer, you must have a Scalable Vector Graphics (SVG) Viewer installed as a plug-in. The Mozilla Firefox browser provides a build-in plug-in. It is recommended that you use Internet Explorer when you are using the Tivoli Performance Viewer for long-term or extended monitoring.
