Overview

We can view the current performance activity of a server using the Tivoli Performance Viewer (TPV) in the administrative console.
TPV monitors the performance activity of all servers on a node, which can include the following:

Application servers
Node agent for the node being monitored

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 is affected. To minimize performance impacts, monitor only those servers whose activity you want to monitor.

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.To start monitoring multiple servers at the same time, select the servers 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 type of data on server activity that you want to view.

Option 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
EJBs
EJB methods
connections pools
thread pools

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 when it detects a long period of inactivity.
