[Mussie Gebregziabiher]

Add torrus (http://torrus.sourceforge.net/) to your list.  The 
extensibility and speed of this tool is awesome./

>BTW: Being MCSE, I've basically started running linux here mainly for the monitoring as the tools were simply ages better than anything I've seen before and flexible enough to satisfy any future need.
