One API to access system information regardless of the underlying platform

Hyperic's System Information Gatherer (SIGAR) is a cross-platform API for collecting software inventory data. SIGAR is core of HQ's auto-discovery functionality, and you can use it to extend auto-discovery behavior.

SIGAR includes support for Linux, FreeBSD, Windows, Solaris, AIX, HP-UX and Mac OSX across a variety of versions and architectures. Users of the SIGAR API are given portable access to inventory and monitoring data including:

* System memory, swap, cpu, load average, uptime, logins * Per-process memory, cpu, credential info, state, arguments, environment, open files * File system detection and metrics * Network interface detection, configuration information and metrics * Network route and connection tables

This is ruby binding for the core API, which is implemented in pure C.
