Using profiling views to analyze data

Prerequisites:

• Launching or attaching to an application

The Profiling Tool provides a number of different views and tables to help visualize the profiling data.

• UML2 Trace Interaction views

• Execution Flow view

• Execution Statistics view

• Code Coverage Statistics*

• Object references table*

• Memory Statistics view *

• Object Allocations view **

• Thread Statistics view**

The profiling views assist you in performing the following types of analysis:

• Analyzing program execution including

  • identifying phases of program execution

  • identifying active threads

  • identifying resource intensive methods

  • studying garbage collection

  • application threading characteristics

• Analyzing method execution including

  • identifying memory intensive classes

  • viewing invocations and callers of a method

  • viewing code coverage*

• Determining performance problems such as identifying memory leaks, application scalability and performance bottlenecks.

* Supported for Java 1.4 and lower profiling

**Supported for Java 1.5 and higher profiling
