You can view the current performance activity of a server using
the Tivoli Performance Viewer (TPV) in the administrative console.
Before you begin
Once monitoring
is enabled, TPV monitors the performance activity of all servers on a node,
which includes the associated application servers and the node agent for the
node being monitored.
About this task
TPV 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 TPV 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 TPV 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 TPV. 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, TPV 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. TPV automatically stops monitoring a server if you the browser
window is closed or if the user logs out.
