Sigar是Hyperic-hq产品的基础包,是Hyperic HQ主要的数据收集组件。它用来从许多平台收集系统和处理信息.
这些平台包括:Linux, Windows, Solaris, AIX, HP-UX, FreeBSD and Mac OSX.
Sigar有C,C#,Java和Perl API,java版的API为sigar.jar sigar.jar的底层是用C语言编写的,它通过本地方法来调用操作系统API来获取系统相关数据。
windows平台:sigar-x86-winnt.dll
linux平台:libsigar-x86-linux.so或
solaris平台: libsigar-x86-solaris.so或libsigar-sparc-solaris.so或libsigar-sparc64-solaris.so
64位平台:分为至强的libsigar-ia64-linux.so和AMD的libsigar-amd64-linux.so,sigar-amd64-winnt.dll

获取cpu信息代码
获取cpu信息代码
// CPU数量(单位:个)
