I think that MIN, MAX, AVG, can apply to either COUNTER or GAUGE in the 
same manner. I think the chief difference between COUNTER and GAUSE is 
simply in the retrieval of the information.

A COUNTER is a reading that accumulates and for each new reading, the 
previous reading must be subtracted. This is typical of interface traffic 
which grows with each reading until the counter 'wraps.'

A GUAGE is a reading that is accurate as is for that reading. There is no 
need to subtract a previous reading. Temperature guages are an example of 
this.
