Tivoli®
Performance Viewer enables administrators and programmers to monitor the overall health of WebSphere®
Application Server from within the administrative console.
Before you begin
In Version 4.0, Tivoli Performance Viewer was named the Resource Analyzer. In Version 5.0, Tivoli Performance
Viewer is a stand-alone Java™ application. In Versions 6.0.x and later, Tivoli Performance Viewer is
embedded in the administrative console. From Tivoli
Performance Viewer, you can view current activity and summary reports, or log Performance
Monitoring Infrastructure (PMI) performance data. Tivoli Performance Viewer provides a simple viewer
for the performance data collected by the Performance Monitoring Infrastructure.
About this task
By viewing Tivoli Performance Viewer 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 Enterprise JavaBeans (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.
Procedure
- 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.
- Monitor current server
activity.
You can view real-time data on the current performance activity of a
server using Tivoli Performance Viewer in the administrative console.
- Use the performance advisors to examine various data while your application is running. The
performance advisor in Tivoli Performance Viewer provides advice to help tune systems for optimal
performance by using collected PMI data.
- Configure user and logging settings
for Tivoli Performance Viewer. These settings may 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 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, Tivoli Performance Viewer enables you
to view data for other products or customer applications that have implemented custom PMI.
- WebSphere Application Server Version 8 for IBM® i requires Portable Application Solutions Environment (PASE),
5761SS1 (IBM i 6.1) or 5770SS1 (IBM i 7.1) option 33, for graphics
- View server performance logs.
You can record and view data that has been logged by Tivoli Performance Viewer in the
administrative console. Be sure to
configure user
and logging settings for Tivoli Performance Viewer.
- Log performance data.
You can record real-time data for later retrieval and analysis.
