You can view the current performance activity of a server
using the Tivoli® Performance
Viewer in the administrative console.
Before you begin
Once monitoring is enabled, Tivoli Performance Viewer monitors
the performance activity of all servers on a node, which includes
the associated application servers.
About this task
Tivoli Performance
Viewer enables administrators and programmers to monitor the current
health of WebSphere® Application
Server. Because the collection and viewing of data occurs in the
application server, performance may be affected. To minimize performance
impacts, monitor only those servers whose resources need to be optimized.
Procedure
- Click Monitoring and Tuning > Performance Viewer > Current® Activity in the
console navigation tree. The Tivoli Performance Viewer current activity
collection is displayed.
- Start monitoring the current activity of a server in either
of two ways:
- Under Server, click the name of the server whose activity
you want to monitor. Clicking on the name starts the monitoring for
the server and displays the activity page for the server.
- Select the check box for the server whose activity you want
to monitor, and click Start Monitoring.
A Tivoli Performance Viewer console
panel is displayed, providing a navigation tree on the left
and a view of real-time data on the current performance activity of
a server on the right.
- From the navigation tree, select the server activity data
that you want to view.

Description |
Advisor |
Use the Performance Advisor to examine various data while
your application is running. The Performance Advisor provides advice
to help tune systems for optimal performance and gives recommendations
on inefficient settings by using collected PMI data. |
Settings |
Configure user
and logging settings for Tivoli Performance
Viewer. These settings can affect the performance of your application
server. |
Summary Reports |
View summary
reports on servlets, enterprise beans (EJBs), EJB methods,
connections pools and thread pools in WebSphere Application Server. |
Performance Modules |
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, Tivoli Performance Viewer enables
you to view data
for other products or customer applications that have implemented
custom PMI. |
What to do next
When you finish monitoring a server, select the server and
click
Stop Monitoring. Tivoli Performance
Viewer automatically stops monitoring a server if the browser window
is closed or if the user logs out.
Avoid trouble: When
using Mozilla Firefox Version 3.5.16, the Tivoli® Performance Viewer
graphical charts do not render correctly. When viewing performance
data, you might see an empty graph or missing data, even though you
selected counters to display in the chart. Use Firefox Version, 3.6.13
or higher, to resolve this problem.
