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 information is available in most operating systems, but each OS has its own way(s) providing it. SIGAR provides developers with one API to access this information regardless of the underlying platform. The core API is implemented in pure C with bindings currently implemented for Java, Perl and C#.

SIGAR offers both source code and binary distributions including native libraries for all supported platforms, examples and documentation. Hyperic SIGAR is licensed under the terms of the Apache 2.0 license.
