Monitoring performance with Tivoli Performance Viewer (TPV)

Tivoli Performance Viewer (TPV) enables administrators and programmers to monitor the overall health of WebSphere Application Server without leaving the administrative console.

Before you begin

In Version 4.0, Tivoli Performance Viewer was originally 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 or log Performance Monitoring Infrastructure (PMI) performance data. TPV provides a simple viewer for the performance data gathered by the Performance Monitoring Infrastructure for WebSphere Application Server.

Why and when to perform this task

By providing the ability to look at TPV data, administrators can determine which part of the application to focus on to improve performance and what configuration settings to change to improve performance. For example, in order to determine what part of the application to focus on, you can view the summary charts for servlets, enterprise beans and Enterprise JavaBeans (EJB) methods, and sort these tables to determine which of these resources has the highest response time. You can then focus on improving the code path for those application resources taking the longest response time.

Steps for this task

  1. Optional: Adjust the Performance Monitoring Infrastructure (PMI) settings for the servers that you want to monitor. The PMI service is enabled by default with a basic set of counters enabled.
  2. Monitor current server activity. You can view real-time data on the current performance activity of a server using TPV in the administrative console.
    • 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 and gives recommendations on inefficient settings by using collected PMI data.
    • Configure user and logging settings for TPV. These settings can affect the performance of your application server.
    • View summary reports on servlets, Enterprise JavaBeans (EJB) methods, connections pools and thread pools in WebSphere Application Server.
    • View performance modules that provide graphics and charts 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.
  3. View server performance logs. You can view data that has been logged by TPV in the administrative console. Be sure to configure user and logging settings for TPV.
  4. Log performance data. You can store real-time data in log files for later retrieval and analysis.
