AppPerfect Java Profiler is built using Eclipse framework hence it integrates seamlessly with any Eclipse version 2. Submitted by Satyen Bhagbole on Sat, AppPerfect Java Profiler. Details Group Tabs Details AppPerfect Java Profiler provides you a unified view of all resources that is memory, methods, threads and monitors to help you understand your JVM's behavior, performance characteristics etc. Faster, efficient and more powerful machines temporarily hide performance and other problems, but errors in code if left unidentified can cause major application as well as system performance issues.
To detect such coding faults manually is an extremely tedious, error prone and expensive task. AppPerfect Java Profiler is designed to assist you find such errors by profiling your application as well as vital resources of the system on which you are running the application.
It will provide you with a finer view of your target application execution and its resource utilization. AppPerfect Java Profiler eliminates the need to spend long hours going through the code, and pinpoints the problems associated with your application. It provides complete and accurate statistical information that helps you trace coding errors in your application. AppPerfect Java Profiler helps you diagnose and resolve performance problems, memory leaks and multi-threading problems in your Java or J2EE server applications to ensure the highest level of stability and scalability for your applications.
AppPerfect Java Profiler provides you with a root-cause analysis of these problems and helps you resolve them. AppPerfect Java Profiler provides you a unified view of all resources that is memory, methods, threads and monitors to help you understand your JVM's behavior, performance characteristics etc. It is one of the best and finest profiler available in the large market of profilers.
This enhances ease-of-use and productivity. Dynamic Instrumentation: AppPerfect Java Profiler uses advanced Dynamic Instrumentation library for extremely low profiling overhead and quick startup time. It can profile any application or appserver even when its not present in supported list provided proper JVM parameters are passed while starting application or appserver. Define New Project - General Settings. Java Profiling must be performed before the code is finally executed and deployed to identify critical issues that affect the stability and quality of the software.
Java Profiling may thus be summarized as measuring statistics of a Java application, specifically in terms of:. Faster, efficient and more powerful machines temporarily hide performance and other problems, but errors in code if left unidentified can cause major application as well as system performance issues.
To detect such coding faults manually is an extremely tedious, error prone and expensive task. The AppPerfect Java Profiler is designed to assist you find such errors by profiling your application as well as vital resources of the system on which you are running the application. AppPerfect Java Profiler is found to be most affordable, cost effective, efficient, reliable and accurate solution by its customers.
We will now try to understand how you can successfully implement Java Profiling for your Java application using AppPerfect Java Profiler. Follow the steps below to create a new project. For details on configuring project properties refer to Setting Project Properties chapter.
Provide the Name of the project and select the "Target" tab to configure your target application for profiling. In this tab you need to configure the Run Configuration for target application. For details refer to Configuring Target Application Settings chapter. For details refer to Profiling an Application chapter. This memory dump is assured to be the exact state of the JVM memory at the time the snapshot was taken. Such a heap snapshot can provide invaluable data in understanding how memory is allocated and used.
Specifically, the Heap snapshot provides a summary of the classes, instances, allocations, out-references and in-references of the objects that are held in the heap at a particular time. For details on Heap Snapshot refer to Heap Browser chapter. Effective memory management ensures optimized performance from any application. Memory Profiling provides information about the memory used by your application.
It shows the allocations, the stack trace for the allocations, the size of the objects and the status of the objects. This information is presented in the form of charts and tables for easy interpretation and clearly shows the high memory consumption areas of the application.
You can also view the details on Garbage collection, the objects which are garbage collected and the time consumed during garbage collection. All the views are updated in real-time providing the profiling data immediately as your application is running. For details refer to Memory Profiling chapter.
Memory Leaks can be defined as an application error whereby memory is allocated but never freed and all references to this memory are lost by the system. Memory Leaks can lead to unchecked memory growth which will slow down your application and eventually crash it. Memory Leak Scenarios feature is designed to help detect possible memory leaks in your application.
To start the scenario click on Start Scenario toggle button. Perform actions in your application based on your usage scenario. Once you have finished executing the scenario, click on the Stop Scenario toggle button. It will then find out differences in the live objects between start and end of scenario. Objects that are created during the scenario run but not disposed by Garbage Collection are shown in the Scenario details tab.
