Description:

The Sigar API provides a portable interface for gathering system
information such as:
- 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 info and metrics
- Network route and connection tables

This information is available in most operating systems, but each OS
has their own way(s) providing it. SIGAR provides developers with one
API to access this information regardless of the underlying platform.
