[c-nsp] how many samples in a 5 minute interface average?

[Scott Granados]

Hi, when doing a show interface you of course get a 5 minute average 
(depending on what you have your interval set to).  How many samples are 
taken over that 5 minute period to generate that average?  It's obviously 
not a sample every 5 minutes because the effects of changes of traffic flow 
are visible over shorter periods (again in relation to the interval).  Is 
there a ratio of samples per interval or samples per second?

Thanks
Scott
