Tivoli Performance Viewer (TPV) 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, 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 task
By 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 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 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 by using collected PMI data.
- Configure user
and logging settings for TPV. 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, TPV 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 TPV in the administrative console. Be sure
to configure user and
logging settings for TPV.
- Log performance
data. You can record real-time data for later retrieval
and analysis.
