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.
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.
