Tivoli Performance Viewer summary report types
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. We can sort the summary table by any of the columns.
Sort by Avg Response Time to find the slowest servlet or JavaServer page (JSP).
Sort by Total Requests to find the servlet or JSP used the most.
Sort by Total Time to find the most costly servlet or JSP.
Enterprise beans
The 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_methods
Sort 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.
Sort by Avg Response Time to find the slowest enterprise beam.
Sort by Method Calls to find the enterprise bean used the most.
Sort by Total Time to find the most costly enterprise bean.
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.
Sort by Avg Response Time to find the slowest EJB method.
Sort by Method Calls to find the EJB method used the most.
Sort by Total Time to find the most costly EJB method.
Connection pools
The connection pool summary lists all data source connections that are defined in the application server and shows their usage over time.
When the application is experiencing normal to heavy usage, the pools used by that application should be nearly fully utilized. Low utilization means that resources are being wasted by maintaining connections or threads that are never used. Consider the order in which work progresses through the various pools. If the resources near the end of the pipeline are under utilized, it might mean that resources near the front are constrained or that more resources than necessary are allocated near the end of the pipeline.
Thread Pools
The thread pool summary shows the usage of all thread pools in the application server over time.
When the application is experiencing normal to heavy usage, the pools used by that application should be nearly fully utilized. Low utilization means that resources are being wasted by maintaining connections or threads that are never used. Consider the order in which work progresses through the various pools. If the resources near the end of the pipeline are under utilized, it might mean that resources near the front are constrained or that more resources than necessary are allocated near the end of the pipeline.
PMI levels and counters required
To view Tivoli Performance Viewer summary reports, the minimum PMI level must be enabled. Otherwise, use the custom monitoring level, and enable the PMI level counters required for the specific report to view.
