Most of the applications today are designed and developed for simultaneous use by a large number of users. At times there are underlying problems in the code, which may cause error conditions such as Memory leaks, Race conditions, Thread locks and so on which if neglected, stretches the use of resources beyond limits, causing the application to slow down or even crash. Thus, it becomes critical for the developer to ensure that the application is available, reliable, scalable and makes the most optimal use of the available resources.
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.
Profiling is the process of monitoring various JVM level parameters such as Method Execution, Thread Execution, Object Creation and Garbage Collection. It will provide you with a finer view of your target application execution and its resource utilization.
The 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.
Early detection and resolution of bottlenecks and performance related issues is a critical step towards improving the stability, efficiency and overall performance of an application. Profiling should be performed early and at regular intervals in the software development life-cycle. 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.
Profiling may thus be summarized as measuring statistics of a particular application, specifically in terms of
AppPerfect Java Profiler delivers application related information to the users in the form of well defined reports and charts. The developer can hence get a complete analysis of the application as the problems areas are distinctly marked in these reports.
AppPerfect offers following products for complete and comprehensive solution for testing and monitoring the performance of your application. These products that are designed to help you test your application throughout the development life-cycle.
AppPerfect Java Unit Test is a feature-rich wrapper for the popular JUnit and HtmlUnit testing frameworks for non-web and web-based Java projects respectively. It provides the Java programmer with an easy to use and fully customizable unit-testing environment, which can be integrated with popular Java IDEs as well as the project's build process.
AppPerfect Java Code Test reads your software code and analyzes it for optimization, errors, coding conventions, complexity and style based on industry-standard rules. Over 750 pre-defined, high-value rules can be applied to your code. AppPerfect Java Code Test is an ideal tool to perform code reviews on an on-going basis to ensure high quality of code.
AppPerfect Java Profiler profiles a Java Virtual Machine to assist you in understanding the behavior of your application as it performs its functions. AppPerfect Java Profiler recognizes that your application does not operate in a vacuum and hence provides a unique blend of Java information combined with operating system information.
AppPerfect App Test performs regression and functional testing of your Windows/Desktop applications. Performing manual functional testing by having a person sit and manually click away at the application is extremely expensive and error-prone. AppPerfect App Test provides the means to perform such labor-intensive activity in an automated manner.
AppPerfect Web Test performs regression and functional testing of your Web applications. Performing manual functional testing by having a person sit and manually click away at the application is extremely expensive and error-prone. AppPerfect Web Test provides the means to perform such labor-intensive activity in an automated manner.
AppPerfect Load Test is a stress/load testing tool that can simulate hundreds of virtual users from a single machine. Features supported include site recording, dynamic variable substitution, cookies support, session tracking, SSL support and run strategies. It can run tests based on a variety of strategies such as burst, incremental, exponential, quadratic or loop. It also provides you a comprehensive solution to monitor various attributes of various operating systems present in your application infrastructure.
The AppPerfect Test Manager is central server with a Web-based UI for accessing various modules in the server. AppPerfect Test Manager consists of five main modules:
Requirements Manager: This module is used to create requirement specifications around which your tests will be designed and executed. Functional, business, performance, technical and usability requirements should be defined here to ensure the tests cover all defined criteria.
Test Manager: Once tests have been designed, the Test Manager can be used to manage the execution of your tests. Automatically running tests on a specific schedule, notification of test results, saving of test results, etc. can be defined in this module.
Results Manager: Once results for your various tests have run a few iterations, the Results Manager can be used to manage the archived results. Trend Analysis of multiple results to detect key quality trends is a key feature of this module. Storage management can also be performed via this module.
Issues Manager: As tests are run, issues such as defects, enhancements, modifications, etc. will occur. This module can be used to create and track such issues. This module is designed as a light-weight issues manager that seamlessly integrates with the rest of the server and is not intended to replace full-featured issues management system.
License Manager: Floating/site licenses are managed using this module. This module acts as the central manager for issuing and reclaiming floating licenses for the AppPerfect products.
The AppPerfect Agentless Monitor is an agentless, Web-based monitoring solution. It helps you monitor your applications and the underlying system resources. The AppPerfect Agentless Monitor consists of:
AppPerfect Monitor: A pure Web-based solution that helps you monitor your application infrastructure. Provides a rules engine to define alerts: a notification server for email and SMS notifications. Also includes a powerful report designer to create custom reports to analyze and understand the performance data.
AppPerfect Monitors: A series of modules designed to support specific devices. AppPerfect Monitor does not use the traditional agents-based approach to monitoring. Apart from being expensive, agents-based approach is also highly complex and error-prone. AppPerfect Monitors are designed to impose negligible overhead on the monitored system. These monitors are superbly optimized programs providing the maximum amount of information while imposing the lowest possible overhead.
Currently, the following devices are supported:
