Monitor performance with Tivoli Performance Viewer (TPV)
Monitor performance with Tivoli Performance Viewer (TPV)
Tivoli Performance Viewer (TPV) enables administrators and programmers to monitor the overall health of WebSphere Application Server from within the administrative console.
In Version 4.0, Tivoli Performance Viewer was named the Resource Analyzer.
In Version 5.0, TPV is a standalone Java application. In Versions 6.0.x and later, TPV is embedded in the administrative console. From TPV, you can view current activity and summary reports,
or log Performance Monitoring Infrastructure (PMI) performance data. TPV provides a simple viewer for the performance data collected by the Performance Monitoring Infrastructure.
About this taskBy viewing TPV data, administrators can determine which part of the application and configuration settings to change in order to improve performance.
For example, you can view the servlet summary reports, enterprise beans, and
EJB methods in order to determine what part of the application to focus on. Then, you can sort these tables to determine which of these resources has the highest response time. Focus on improving the configuration for those application resources taking the longest response time.
Use the performance advisors to examine various data while your application is running.
The performance advisor in TPV provides advice to help tune systems for optimal performance by using collected PMI data.
View summary reports on servlets, EJB methods, connections pools and thread pools in WebSphere Application Server.
View performance modules that provide graphs and of various performance data on system resources such as CPU utilization, on WebSphere pools and queues such as database connection pools, and on customer application data such as servlet response time. In addition to providing a viewer for performance data, TPV enables you to view data for other products or customer applications that have implemented custom PMI.
