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 and the administrative
agent for the node being monitored.
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.
-
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.To start monitoring multiple
servers at the same time, select the servers and click Start Monitoring.
- 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.
