Hello,

	Adv = advantages and Dis = disadvantages

I found ntop to be stable ... it all depends on what command line switches you specify.

But like all performance monitors they are not designed to be run forever. You should be downloading the data from ntop and saving it in a DB of some sort and then restart the process.
