DESCRIPTION

       The statgrab library provides a cross-platform interface to get several system statistics.
       System statistics aren't standardised, so the statgrab library tries to  choose  the  most
       important values over all supported operating systems. This implies that some values might
       not be available on every OS while some specific values are  missing  when  there  are  no
       counterparts on any other OS.

       The libstatgrab is organised in components, each for interrelated statistics.

       The  library was originally written to support the i-scream central monitoring system, but
       has since become a standalone package. It has  been  ported  to  work  on  Linux,  NetBSD,
       FreeBSD, OpenBSD, DragonFly BSD, Solaris, HP-UX, AIX and Cygwin.
