如何使用Jconsole监控Java程序？ [英] How to monitor a Java program using Jconsole?

问题描述

我编写了一个程序，使用2个线程从1到200打印数字。

现在我想使用JConsole监控这个程序。

基本上我想学习如何使用JConsole来监控应用程序。

我搜索谷歌但却没有找到有用的东西。

我怎样才能做到这一点？

当我开始 bin文件夹中的jconsole.exe 。它要求输入主机名和端口号。
在我的情况下，我猜没有。
有人可以指导吗。

解决方案

假设你有一个班级测试在包 p1 下，你有代码使用2个线程（你想要监控）打印1到200的数字。

所以要使用 也是出于此目的。

I have written a program to print number from 1 to 200 using 2 threads.

Now I want to monitor this program using JConsole.

Basically I want to learn how to use JConsole for monitoring an application.

I searched google but couldn't find something useful.

How I can achieve this?

When I started jconsole.exe in bin folder. It asks for hostname and port number. Here in my case, there is none, I guess. Can somebody guide.

解决方案

Let's say you have a class Test under package p1 where you have the code to print numbers from 1 to 200 using 2 threads(which you want to monitor).

So to use jconsole for monitoring your application, you would need to compile and execute your code first and while your code is executing...

• Start -> Run -> jconsole.exe and hit/press Enter

• Select the application which you want to monitor and then click Connect.

Alternatively,you can use VisualVM for this purpose as well.
