You can use the Tivoli® Performance
Viewer to start and stop performance monitoring; view Performance
Monitoring Infrastructure data in chart or table form as it occurs
on your system; and, optionally, log the data to a file that you can
later review in the same viewer.
About this task
The Tivoli Performance
Viewer (TPV) is a powerful application that allows you view a variety
of details of about the performance of your server. The section entitled "Monitoring
performance with Tivoli Performance
Viewer" in the WebSphere® Application Server Information
Center contains details about how to use this tool for a variety of
purposes, and you should see that resource for complete instructions
on using this program. This section is limited to discussing the viewing
of performance data for events specific to WebSphere Enterprise
Service Bus.
The
performance viewer enables administrators and programmers to monitor
the current health of
WebSphere ESB. Because
the collection and viewing of data occurs on the process server, performance
is affected. To minimize performance impacts, monitor only those servers
whose activity you want to monitor.
Note: When
viewing these statistics, you should not mix counter-type statistics
with duration-type statistics. Counters are cumulative, and the scales
against which they are graphed can quickly grow depending on your
application. Duration statistics, in contrast, tend to remain within
a certain range because they represent the average amount of time
that it takes your system to process each event. Consequently, the
disparity between the statistics and their relative scales may cause
one or the other type of statistic to appear skewed in the viewer
graph.
