Java Profiling is the process of analyzing an application to identify and pinpoint memory or performance-related issues. One such tool, among various others, is a Java profiler. To handle that, a Java developer requires a set of specific tools for maintaining the performance of the application by monitoring multiple JVM level parameters. Debugging these types of performance issues has always been a challenging task for a java developer. All this information is required to monitor the area of improvements in the application and to identify and remove if any bottleneck is present. Garbage Collection, CPU utilization, etc.

Many questions are needed to be answered to maintain the performance of an application for instance, is the total memory allocated by the code? How will a change in code and design affect the performance? Memory usage by the application. Thread profiling not only has a separate view section in JProfiler, it is also tightly integrated into the CPU profiling views.Every java developer aims to write the best and most efficient code, but while developing complex and large enterprise applications, it is not that easy to monitor all the JVM internal components to maintain efficiency. A whole range of otherwise opaque problems can be solved when using JProfiler, such as increasing liveness in a multi-threaded application that uses too much locking. Without a thread profiler, you only have a minimal chance to tackle such issues. The integrated thread profiler: Problems related to threading are much more frequent than one might assume.With JProfiler, you have a decisive advantage when trying to find the reason for a problem. However, CPU data can be overwhelming in its level of detail and the way data is collected can make a huge difference in usability. The powerful CPU profiler: Fixing performance bottlenecks is the most frequent use case for a profiler.
JProfiler shows you how your profiling settings will impact performance and offers you templates to quickly select profiling settings for common use cases. In fact, you can start your application with the JProfiler agent and attach the JProfiler GUI at a later time.
With its JEE support, JProfiler bridges the gap between a code profiler and a high-level JEE monitoring tool. Also, JProfiler adds a semantic layer on top of the low-level profiling data, like JDBC, JPA/Hibernate, JMS and JNDI calls that are presented in the CPU profiling views. Support for Java Enterprise Edition: Dedicated support for JEE is present in most views in JProfiler.Database profiling for JDBC, JPA and NoSQL: JProfiler's JDBC and JPA/Hibernate probes as well as the NoSQL probes for MongoDB, Cassandra and HBase show the reasons for slow database access and how slow statements are called by your code.On all levels, JProfiler has been carefully designed to help you get started with solving your problems. Configuring sessions is straight-forward, third party integrations make getting started a breeze and profiling data is presented in a natural way. Ease of use: JProfiler is just that: simple and powerful at the same time.JProfiler's intuitive UI helps to resolve performance bottlenecks, pin down memory leaks and understand threading issues.
