JProfiler's heap walker has also been enhanced. Executors, thread start and AWT/SWT events can all be tracked with the request tracking function. For example, you can use this function to determine the time it takes to complete an asynchronous task, or to find out the origin of the asynchronous task. Request tracing connects call points and execution points between different threads in the call tree view. JProfiler also introduces the concept of request tracking, which simplifies the analysis of parallel applications and multi-threaded applications.

Please note that this version also adds a run script trigger, which is also a way to execute code when a specific method is called, and can replace simple custom probes. You can directly add or modify custom probes without restarting the application to be analyzed. You can specify the method to be intercepted in the application, and create an "intercepting script" that will be called with the assistance of the JProfiler code editor. JProfiler also provides a custom probe wizard, which allows you to customize probes in the JProfiler GUI. It provides a set of APIs that can be used to develop custom probes and deploy the custom probes with the application to be analyzed. JProfiler also supports the creation of custom probes. These built-in probes can all be configured in the session settings of JProfiler. The probe also has an object view that displays detailed information and statistical information, a hotspot view that displays the most expensive method call overhead, and a telemetry view that can graphically display the telemetry information released by the probe. For example, the JDBC probe will display events for connecting to the database or executing queries. The probe also has an event view, which also displays event, thread, and stack trace information. For example, the database connections displayed in the timeline can reflect when these connections are idle, when a statement is returned, or the time period during which a batch transaction is executed. For long-lived objects, the probe has a timeline view.
JProfiler now has built-in probes for analyzing JDBC, JMS, JNDI, Servlet, files, Sockets, and processes, and can record and analyze the data of each subsystem.
Use the API to customize the probe, or you can configure it directly in the JProfiler GUI.
