Log performance data with TPV

Log performance data with TPV

Overview

The Tivoli Performance Viewer (TPV) can store real-time data in log files which can be replayed at a later date.
Before starting, configure TPV log settings. After logging is complete, we can view the data with the Tivoli Performance Viewer.
Create and view logs in the admin console.
When using the Tivoli Performance Viewer for long-term or extended monitoring, IBM recommends using Internet Explorer with a Scalable Vector Graphics (SVG) Viewer installed as a plug-in
Performance degradation and memory leaks can occur when usng the Mozilla Firefox browser and Tivoli Performance Viewer to monitor the appserver for an extended period of time.

TPV automatically compresses the log file when it finishes writing. There is only a single log file in each .zip file. The log file will have the same name as the .zip file.

Adjust the log view as needed. By default, the data replays at the Refresh Rate specified in the user settings.

Stop Stop the log at its current location.
Play Begin playing the log from its current location.
Fast Forward Load the next data point every three (3) seconds.
Fast Forward 2 Load ten data points every three (3) seconds.

We can view multiple logs at a time. After a log has been loaded, return to the View Logs panel to see a list of available logs. At this point, we can load another log.
TPV automatically compresses the log file when finishes writing it. The log does not need to be decompressed before viewing it, though TPV can view logs that have been decompressed.
