Neckbeerd

Neckbeerd (/ˈnekbɪərd/) is your local system problem finder.

On the basis of the output of common system diagnostic tools (like ps, top, vmstat, iostat, sar, mpstat, slabtop, free, etc.) and arcane knowledge combined into a set of rules (called a policy) neckbeerd gives you it's best guess about the state of the system (a diagnosis).

You can define your own policies or add plugins (i.e. for providing application specific insight).
