Viewing PMI data with TPV

You can use the Tivoli Performance Viewer (TPV) to view Performance Monitoring Infrastructure (PMI) data in chart or table form.

Before you begin

TPV monitors the performance activity of all servers on a node. This article assumes that one or more servers have been created and are running on the node, and that PMI is enabled.

TPV displays graphics in either the Scalable Vector Graphics (SVG) format or as a static image in the JPG format. If you do not have the Adobe SVG browser plug-in installed, you are prompted to download and install it. If you select not to install the plug-in (by selecting Cancel), TPV displays the static image. Installing the Adobe SVG plug-in is advantageous for several reasons. First, the SVG format provides interactive graphics that provide additional information when you hover your mouse over a point, line, or legend item. The SVG format also enables you to click a point and see details for it. Secondly, using the SVG format provides a performance benefit because the work to display the SVG image is done on the client side. When viewing a static image, the application server must convert the SVG image into a static image, which is a processor and memory intensive operation. If your browser is Internet Explorer 7, the Adobe SVG installation prompt might be inaccessible. To resolve the problem, reinstall Adobe SVG.

If you experience problems with SVG, see Scalable Vector Graphics problems for more information.

About this task

You view performance modules when your server is experiencing performance problems. For example, a common performance problem occurs when individual sessions are too large. To help view data on a session, you can view the Servlet Session Manager PMI module and monitor the SessionObjectSize counter to make sure that Session Object Size is not too large.

Performance modules are shown in the TPV current activity settings in the administrative console.

Note: When you create a second application server under WebSphere Application Server, TPV cannot display the PMI data for the second application server such as WebSphere Portal Server. For more information, refer to the technote at: http://www.ibm.com/support/docview.wss?rs=180&=swg21247170.
