View summary reports

Overview
Summary reports are available for each appserver. Before viewing reports, make sure data counters are enabled and monitoring levels are set properly. See Setting performance monitoring levels .
The standard monitoring level enables all reports except the report on Enterprise JavaBeans (EJB) methods. To enable an EJB methods report, use the custom monitoring setting and set the monitoring level to Max for the EJB module.

Overview
Tivoli Performance Viewer provides the following summary reports for each appserver:
Enterprise beans
Enterprise beans show the total number of method calls, average response time, and multiplication of total method calls by average response time for all the enterprise beans in a table. Enterprise beans provide a sorting feature to help you find which enterprise bean is the slowest or fastest and which enterprise bean is called most frequently.
EJB Methods
EJB Methods show the total number of method calls, average response time, and multiplication of total method calls by average response time for the individual EJB methods in a table. EJB Methods provide a sorting feature to help you find which EJB method is the slowest or fastest and which EJB method is called most frequently.
Servlets
Servlets show the total number of requests, average response time, and multiplication of total requests by average response time for all the servlets in a table. Servlets provide a sorting feature to help you find which servlet is the slowest or fastest and which servlet is called most frequently.
Web Container Pool
Web Container Pool shows charts of pool size, active threads, average response time, and throughput in the Web container thread pool
Object Request Broker (ORB) Thread Pool
ORB Thread Pool shows charts of pool size, active threads, average response time, and throughput in the ORB thread pool.
Connection Pool
Connection Pool shows a chart of pool size and pool in use for each data source.
1. Click the appserver icon in the navigation tree.
2. Click the appropriate column header to sort the columns in the report.

Results
If the instrumentation level excludes a counter, that counter does not appear in the tables and charts of the performance viewer. For example, when the instrumentation level is set to low, the thread pool size is not displayed because that counter requires a level of high.
Note that monitoring levels can also be set through the console
