本文實例講述了java獲得辦事器根本信息的辦法。分享給年夜家供年夜家參考。詳細以下：
應用第三方的jar包：（Hyperic-hq官方網站：http://www.hyperic.com） 經由過程Hyperic-hq產物的基本包sigar.jar來完成辦事器狀況數據的獲得。Sigar.jar包是經由過程當地辦法來挪用操作體系API來獲得體系相干數據。Windows操作體系下Sigar.jar依附sigar-amd64-winnt.dll或sigar-x86-winnt.dll，linux 操作體系下則依附libsigar-amd64-linux.so或libsigar-x86-linux.so
