You can configure some EAServer subsystems to log trace data to the server log file, including:
Thread monitors, to log performance data for the components to which you have assigned the monitor. See “Thread monitors” for more information. You can assign thread monitors that have no thread limit to track the number of threads that a component is running on.
Tracing of SQL commands run through a data source, enabled in server properties. See “Log/Trace tab” in Chapter 3, “Creating and Configuring Servers,” in the System Administration Guide.
Tracing of JMS commands, enabled in server properties. See “Log/Trace tab” in Chapter 3, “Creating and Configuring Servers,” in the System Administration Guide.
