JProfiler integrates into your environment: We provide native agent libraries for a wide range of platforms, both for 32-bit and 64-bit JVMs. The ant tasks bundled with JProfiler allow you to perform all command line operations from your build script.īROADEST SUPPORT FOR PLATFORMS, IDES AND APPLICATION SERVERS This includes the ability to profile, export snapshot data and create snapshots comparisons from the command line. JProfiler has strong support for command line operations. The rich functionality around snapshot comparisons makes it easy to track progress. JProfiler is ideally suited as a QA tool, both during development as well as for dedicated QA teams. Questions like why objects are not garbage collected are answered with a single click of the mouse. Each view provides you with essential insights on the selected objects and lets you switch to different objects sets. 5 different views and lots of inspections show different aspects of the current set of objects. JProfiler’s heap walker offers you an intuitive interface to solve both simple and complex memory problems. And what’s more, all these views are also available for your own custom probes that you can configure on the fly within JProfiler.įinding a memory leak can be impossible without the right tool. Each of these probes has its own set of useful views that gives you general insight, highlights performance problems and allows you to trace single events. In addition to the Java EE subsystems like JDBC, JPA/Hibernate, JSP/Servlets, JMS, web services and JNDI, JProfiler also presents high level information about RMI calls, files, sockets and processes. JProfiler has a number of probes that show you higher level data from interesting subsystems in the JRE.

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.

In addition, the call tree is split up for each request URI. For example, in the JEE aggregation level you see the call tree in terms of the JEE components in your application. From the JDBC timeline view that shows you all JDBC connections with their activities, through the hot spots view that shows you slow statements to various telemetry views and a list of single events, the database probes are an essential tool for getting insight into your database layer.ĮXCELLENT SUPPORT FOR JAVA ENTERPRISE EDITIONĭedicated support for JEE is present in most views in JProfiler. 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.ĭATABASE PROFILING FOR JDBC, JPA AND NOSQLĭatabase calls are the top reasons for performance problems in business applications. Configuring sessions is straight-forward, third party integrations make getting started a breeze and profiling data is presented in a natural way. JProfiler is just that: simple and powerful at the same time.

At the same time, you do not want to spend time learning how to use the tool. When you profile, you need the most powerful tool you can get. When it comes to profiling, only the best tool is good enough.Ĭheck out below what makes JProfiler the top choice for profiling your applications on the JVM: Pin down memory leaks and understand threading issues. JProfiler’s intuitive UI helps you resolve performance bottlenecks,
