Live memory: Information about class/class instance. Telemetries: Tendency view of heap, thread, GC, CPU load, classesī. Here’s what the JProfiler’s GUI looks like:Ī. Triggers: usually use in offline mode, tell JProfiler Agent when to trigger what behavior to collect the specified information. Offline profiling: the third option in the pictureģ.2 Session settings: A.Prepare for profiling: the second option in the picture.Profile at startup: the first option in the picture below.Attach mode: JProfiler agent can be loaded directly into a running JVM.Important concept of JProfiler 3.1 start up mode JProfiler GUI Render present the final display effect.ģ.JProfiler GUI Socket returns the information received to the JProfiler GUI Render.The JProfiler Agent saves the collected information to memory in a certain rule.For example: the life cycle of a thread The lifecycle of the JVM The life cycle of classes The life cycle of an object instance Real-time information on heap memory, and so on.JVMTI collects information about the current JVM based on registered events.After the JProfiler Agent receives the instruction, it converts the instruction to an event or instruction that needs to be monitored, to register on JVMTI.JProfiler GUI sends instructions to the JProfiler Agent in the analyzed JVM through the socket(default port 8849).Users give instruction for monitoring in the JProfiler GUI.Broadest support for platforms, IDEs and application servers.The powerful CPU, Thread, Memory profiler.JProfiler provides many IDE integration and application server consolidation. JProfiler’s intuitive GUI helps you find performance bottlenecks, pin down memory leaks and resolve threading issues. JProfiler is a full-featured Java profiling tool (profiler) dedicated to analyzing J2SE and J2EE applications. It is developed by ej-technologies and currently in version 10.1. JProfiler is a Java profiler combining CPU, Memory and Thread profiling in one application. Demo (profile java code with Jprofiler) 1.
