Introduction

The Kunpeng DevKit Java Profiler is a performance analysis and tuning tool for the Kunpeng platform. This document describes how to use the Java Profiler to perform real-time profiling and sampling profiling on the running Java program, find program problems, and tune the program based on the analysis results to achieve optimal running of the Java program.

Networking Environment

This practice uses CentOS 7.6 as an example. Perform similar operations for other OSs on the Kunpeng platform.
