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.

- 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.
