Java获取服务器磁盘负载率1、在远程server里搭建一个http服务java代码硬盘使用比例，并支持某种服务端语言（如.net或php之类）
2、用服务端语言获取到服务器的磁盘信息java代码硬盘使用比例，把结果输出
3、在本地用JS写一段AJAX脚本，远程请求服务端写好的程序，得到结果，并展示给用户
html
head
title提取硬盘序列号/title
script
function disk() {//硬盘序列号 信息
var locator = new ActiveXObject ("WbemScripting.SWbemLocator");
var service = locator.ConnectServer(".");
var properties = service.ExecQuery("SELECT * FROM Win32_DiskDrive");
var e = new Enumerator (properties);
document.write("table border=1");
for (;!e.atEnd();e.moveNext ())
{
var p = e.item ();
document.write("tr");
document.write("td" + p.signature + "/td");
document.write("/tr");
}
document.write("/table");
}
/script
/head
body
input type="button" value="https://www.04ip.com/post/硬盘序列号" onclick="disk()"

在这上找的代码：
对于写过ASP或.net 的人来说,通过asp或.net 语言来获得客户端的硬件信息是很熟悉的.但如何通过javascript这种客户端脚本来获得客户端的信息呢?请看以下实例:
!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"
html
head
titlejavascript获得客户端硬件信息-;/title
meta name="GENERATOR" content="Microsoft Visual Studio .NET
7.1"
meta name="vs_targetSchema"
content=""
script id=clientEventHandlersJS language=javascript
!--
function Button2_onclick() {//CPU 信息
var locator = new ActiveXObject ("WbemScripting.SWbemLocator");
