Shows a schedule of activities with a chart of loaded classes. Shows a schedule of garbage collection activities. Shows a timeline of the activity of a chart of active objects and arrays. Show a heap usage status and heap size activity schedule. To observe the internal state of JVM, JProfiler provides different telemetry survey views, as shown below:
Shows an activity schedule along with thread activity and thread status.ĭisplay a list, including all active threads and their current activity status. Show a diagram of the access queue starting from the selected method, class, package or J2EE component.įor thread analysis, JProfiler provides the following views: The hotspot can be calculated according to method request, JDBC, JMS and JNDI service request and according to URL request. The backtracking tree can be displayed for each hot spot. The request tree can be split according to the different needs of Servlet and JSP for URL.ĭisplay a list of the most time-consuming methods. JDBC, JMS and JNDI service requests are all annotated in the request tree. The CPU view section includes:ĭisplay 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. It can also provide the function of combining input view and output view.ĭisplay instance and class data for a single object.ĭisplay a histogram of the resolution time of the recorded object. Provide the display function of index map for single object and "show the path to the garbage collection root directory". The heap walker has five views:ĭisplay distribution tree and distribution hotspot for all record objects. In JProfiler's Heap Walker, you can take a snapshot of the heap status and find objects of interest by selecting steps. For each hot spot, its tracking record tree can be displayed. You can mark the current value and display the difference value. You can mark the current value and display the difference value.ĭisplay a request tree or method, class, package, or J2EE component with annotated allocation information for the selected class.ĭisplay a list, including methods, classes, packages, or J2EE components assigned to the selected class. Shows the class or package of all recorded objects.
All views have several aggregation layers and can display existing objects and objects that are garbage collected.ĭisplay class or package of all objects on the heap of status statistics and size information.
#Jprofiler tutorial update#
The memory view part of JProfiler can provide a dynamic memory usage update view and a view that displays information about the memory allocation status.
