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操作系统下Sigar.jar 依赖sigar-amd64-winnt.dll或sigar-x86-winnt.dll,linux 操作系统下则依赖libsigar-amd64-linux.so或libsigar-x86-linux.so

Sigar API 提供一个方便的接口来收集系统信息,如:
◆系统内存,页面交换,cpu,平均负载,运行时间,登录信息
◆每个进程占用的内存,cpu,帐号信息,状态,参数,环境,打开的文件
◆文件系统探测和度量
◆网络接口探测,配置信息和度量
◆网络路由和连接表
