[rrd-users] Re: Manipulating and Graphing Data

Ok...well...DERIVE doesn't give me accurate numbers. Not even close. That
is why I am trying to ask the community for a solution to the problem.

Well...I'm really confused. Here is what it's states from the beginner's
guide:

"GAUGE does not save the rate of change. It saves the actual value itself. "
Values = 300, 600, 900, 1200
Step = 300 seconds
COUNTER DS = 1, 1, 1, 1
DERIVE DS = 1, 1, 1, 1
ABSOLUTE DS = 1, 2, 3, 4
GAUGE DS = 300, 600, 900, 1200Could you clarify this? So, has anyone
out there come up with a solution for this type of monitoring that could
provide me some clues? Thanks!tv----- Original Message -----
