JDBC, JMS and JNDI service requests are all annotated in the request tree. The CPU view section includes:Ĭall tree Access tree: displays an accumulated top-down tree, which contains all the access queues recorded in the JVM.

All views can be gathered on different layers such as methods, classes, packages or J2EE components. Thread or thread group and thread status can be selected by all views. JProfiler provides different methods to record the access tree to optimize performance and details. Time: Display a histogram of the resolution time of the recorded object. It can also provide the function of combining the input view and the output view. References Index: Provides the display function of the index map for a single object and 'show the path to the garbage collection root directory'. The heap walker has seven views:Ĭlasses: Show all classes and their instances.Īllocations: Display the allocation tree and allocation hot spots for all record objects.īiggest Objects: display objects that take up more memory In JProfiler's heap walker (Heap walker), you can take a snapshot of the heap condition and can find objects of interest by selecting the next step. For each hot spot, its tracking record tree can be displayed. You can mark the current value and display the difference value.

The memory view part of JProfiler can provide a dynamic memory usage update view and a view showing information about the memory allocation status. On the overview page, we can clearly see the trends of indicators such as memory usage, garbage collection activities, class loading, number and status of threads, and CPU usage over time. In order to reduce the impact, often need to be used together with Filter. The disadvantage is that if there are more classes to be analyzed, it will have a greater impact on application performance. Instrumentation-full function mode, statistical information is also accurate.

The advantage is that it has a small impact on system performance, but the disadvantage is that certain features are not supported (such as method-level statistics). Sampling-suitable for scenarios that do not require complete data accuracy.JProfier provides two data collection modes, Sampling and Instrumentation. Introduction to main functions Data collection mode Monitor the occupancy of heap memory and the number of object instances created to find out the cause of memory leaks ģ.
