systats is written as a part of my ongoing project to create a system monitoring and alerting system, SyMon. Initially, metrics collection was done as a part of SyMon codebase, but to make the maintainability and compatibility simple, it was taken out as a separate module, systats.

Currently tested on Ubuntu and CentOS.

)

func main() {
