篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了java调用windows的wmi获取设备性能数据相关的知识，希望对你有一定的参考价值。
java调用windows的wmi获取监控数据（100%纯java调用windows的wmi获取监控数据）
转：http://my.oschina.net/noahxiao/blog/73163
纯java主要体现在可以跨平台调用com。所用的是j-Interop，它是100%纯java实现的com的调用
1、环境准备
a、windows要开启Remote Registry与Windows Management Instrumentation服务
b、修改安全策略
我系统是英文的，如果是中文系统，翻译为中文，相对应的查找并修改。
Administrative Tools>Local Security Policy>Local Policy>Security Policy>Network access: Sharing and security model for local accounts
修改为Classic（经典）
c、禁用放火墙
d、window2008系统注册表越狱（高版本的win）
需要修改regedit中HKEY_CLASSES_ROOT\CLSID\{76A64158-CB41-11D1-8B02-00600806D9B6}的权限，windows2008不再给Administrators完全控制权。
下载SetACL.exe，下载地址：http://files.helgeklein.com/downloads/SetACL/current/SetACL%20(executable%20version).zip
set_wmi_reg_acl.cmd
1
SetACL.exe -on "HKEY_CLASSES_ROOT\CLSID\{76A64158-CB41-11D1-8B02-00600806D9B6}" -ot reg -actn setowner -ownr "n:Administrators"
2
SetACL.exe -on "HKEY_CLASSES_ROOT\CLSID\{76A64158-CB41-11D1-8B02-00600806D9B6}" -ot reg -actn ace -ace "n:Administrators;p:full"
以超级管理员身份执行这个cms，就会把owner与完全控制权限授予Administrators组
2、程序代码

4、总结
j-Interop纯java跨平台，我就是linux系统。
用j-Interop就可以很方便的调用windows系统com，虽然这里只演示了WMI。
如果关心WMI与监控的话，建议去opennms-wmi看一看，他们有更好api封装（底层也是j-Interop）。
以上是关于java调用windows的wmi获取设备性能数据的主要内容，如果未能解决你的问题，请参考以下文章
