The Tivoli Performance Viewer (TPV) provides five different summary reports that make important data quickly and easily accessible. View summary reports to help you find performance bottlenecks in your applications and modules.
Before you begin
This article assumes that one or more applications or modules are deployed and running on one or more servers.Why and when to perform this task
You can view TPV summary reports on the following:Servlets | The servlet summary lists all servlets that are running
in the current application server. Use the servlet summary view to quickly
find the most time intensive servlets and the applications that use them,
and to determine which servlets are invoked most often. You can sort the summary
table by any of the columns. Tips
|
Enterprise beans | The Enterprise JavaBeans (EJB) summary
lists all enterprise beans running in the server, the amount of time spent
in their methods, the number of EJB invocations, and the total time spent
in each enterprise bean.total_time = number_of_invocations * time_in_methodsSort the various columns to find the most expensive enterprise bean. Also, if the PMI counters are enabled for individual EJB methods, there is a check box next to the EJB name that you can select to see statistics for each of the methods. Tips
|
EJB methods | The EJB method summary shows statistics for each EJB
method. Use the EJB method summary to find the most costly methods of your
enterprise beans. Tips
|
Connection pools | The connection pool summary lists all data source connections
that are defined in the application server and shows their usage over time. Tip
|
Thread pools | The thread pool summary shows the usage of all thread
pools in the application server over time. Tip
|
The default monitoring level enables all reports except the report on EJB methods. To enable the EJB method summary report, configure PMI to use a set of statistics that includes EJB method metrics (All or Custom).
You view TPV summary reports in the administrative console.
