Sigar是Hyperic-hq產品的基礎包,是Hyperic HQ主要的數據收集組件。它用來從許多平台收集系統和處理信息.
這些平台包括：Linux, Windows, Solaris, AIX, HP-UX, FreeBSD and Mac OSX.
Sigar有C，C#，Java和Perl API，java版的API為sigar.jar sigar.jar的底層是用C語言編寫的，它通過本地方法來調用操作系統API來獲取系統相關數據。Windows操作系統下Sigar.jar 依賴sigar-amd64-winnt.dll或sigar-x86-winnt.dll，linux 操作系統下則依賴libsigar-amd64-linux.so或libsigar-x86-linux.so
由於每個平台都要依賴.dll 所以的GitHub上發現了oshi
