Monitoring 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 V4.0, Tivoli Performance Viewer was named the Resource Analyzer.
In V5.0, 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.
Overview
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.
- WebSphere Application Server V6.1 for i5/OS requires Portable
Application Solutions Environment (PASE), 5722SS1 option 33, for graphics.
- 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.
