JProfiler helps with sorting the methods with their total execution times.Īs shown above, we can see method to read data from Redis Cache is taking the most time. Call TreeĬall Tree shows hierarchical view of all the methods calls during the execution of your application. This is a great view to analyze what might be the culprit in your application.
In CPU Views, you can find any specific method you suspect might be causing performance issues. Overview page on Telemetries as shown below will give you an idea about metrics such as garbage collection activity, memory, threads, classes, and CPU load.ĬPU views display the number of executions, call relationships of each method in the application. We will go through these key concepts from JProfiler snapshot data now. In this snapshot, we will have data for performance analysis number of objects generated, method calls, garbage collection, memory leaks. Once the profiling is complete, JProfiler GUI should provide a snapshot of the profiled data. If you are running a performance test on your application, you will stop the profiling when the performance test stops.

How to analyze application performance using JProfiler In short, you are connecting JProfiler GUI to a remote JProfiler agent that is profiling your application. To do this, you will need the IP address of the remote machine as well as the port where the JProfiler agent is running. And from your local JProfiler installation, you will connect to the JProfiler agent.
In remote mode, you will start your JProfiler agent on a remote machine, probably the same machine where the application is running. In this mode, the application and JProfiler are running on the same machine. If you run in local mode, you have to choose data collection mode when starting the JProfiler. JProfiler offers two modes to start the profiling of an application. How to run JProfiler on a running application If you are doing performance analysis, this should be your default choice even with the drawback, it provides large data that is helpful to analyze performance. The advantage is the accuracy of the data.
Sampling – This does not necessarily provide the accuracy of the collected data.There are two ways you can collect data while using JProfiler. I will not be covering that in this post. JProfiler also provides database analysis that can help in understanding if there are any performance issues with database queries. Therefore, it helps to fix memory leak issues. Allocations – You can analyze the objects on the heap, reference chains, and garbage collection.Thread and Lock – To find any multi-threading issues, you should check the thread and lock analysis that JProfiler provides.Method Calls – This shows what your application is doing with method calls and where the performance can be improved.JProfiler focuses on three different topics that can help developers to analyze their application. Previously, I had shown how to use JProfiler for performance testing.
#Visualvm vs jprofiler software
In this post, I want to detail a few key concepts about using JProfiler.Įvery software developer has to use JProfiler or similar tools VisualVM or JDK bundled tools when improving the performance of an enterprise application. The most common usage is for CPU Profiling or Memory analyzing. E-J Technologies has developed this tool. JProfiler is a tool for analyzing what is going on inside a JVM.
