Tivoli Performance
Viewer monitors the performance activity of all servers on a node.
This topic assumes that one or more servers have been created and
are running on the node, and that
.
newfeat Deprecated feature: Tivoli Performance
Viewer 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), Tivoli Performance Viewer 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.
depfeat
newfeat For transitioning users: In Version 8,
the Tivoli Performance Viewer
graph uses Dojo technology for plotting the performance activity rather
than the Scalable Vector Graphics (SVG) format. The Dojo format provides
a better user experience and is more processor and memory efficient
for the application server. The SVG format is still supported but
is deprecated in Version 8 of this product. To use the SVG format
and image format, set the JVM property to
false;
for example:
com.ibm.websphere.tpv.DojoGraph=false.
If the property is set to
false, Dojo is disabled
and Tivoli Performance Viewer
displays interactive graphics using the SVG format or non-interactive
graphics using the JPG format. When you specify to use the SVG format
by setting
com.ibm.websphere.tpv.DojoGraph=false,
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), Tivoli Performance Viewer displays
the static image. If your browser is Internet Explorer 7, the Adobe SVG installation prompt might
be inaccessible. To resolve the problem, reinstall Adobe SVG. By default, this property is set
to a value of
true to use the Dojo format.
