Re: Node throughput and packet delay



	Ok, then maybe we need a set of basic monitoring functions wich produce 
basic output files. What I mean with basic output files is the kind of files 
that can be fed in Xgraph for example.
	
	We would need to know what would be a good set: 
	- data that is of general use (like packet delays?)
	- data that is easely collectable, i mean wich does not depend on the 
protocols used.
	- functions that are ready-to-use (as much as trace-all for example)
	
	I think stuff like bandwidth utilisation and packet delays are data 
pertinent to a majority of users. But then, that's my very own opinion.
