![]() ![]() There are two types of lightweight profilers Aspect profilers and Java agent profilers. Products that offer this are XRebel and Stackify Prefix. Lightweight profilers highlight your application with additional abstraction by injecting themselves right into the code. This is a good way for developers to track CPU usage and it also provides a CPU sampling feature to track and aggregate CPU time by class and method to help zero in on hot spots.Ĭons Require a direct connection to the monitored JVM this ends up limiting usage to development environments in most cases and it also slows down your application a good deal of processing power is required for the high level of detail provided. Pros JVM profilers will track all method calls and memory usage. ![]() Examples of the Products like VisualVM, JProfiler, YourKit, and Java Mission Control. Standard JVM profilers A standard Java profiler certainly provides good information, but not necessarily the most valuable information. What are the Different Java Code Profilers? So now let us spend some time understanding different code profilers out there. Research on continuous profiling has shown it is accurate and cost-effective. ![]() This approach alleviates the need to develop accurate predictive load tests and benchmarks for the production environment. When profiling a Java application, you can monitor the Java Virtual Machine (JVM) and obtain data about application performance, including method timing, object allocation, and garbage collection.Ĭontinuous profiling refers to profiling the application while it executes in a production environment. Profiling is the process of examining an application to locate memory or performance-related issues. So let us first start by understanding the basics In this blog post, I would like to walk readers through the different Java code profilers available and highlight the pros and cons of each of the available profilers. ![]()
