It all depends on what you want to see.   If you want to see the actual values, use GAUGE, and you will see the actual rise and fall in the data.  DERIVE will take the new number and subtract the old number and then divide by step (default 300) but it allows for negative numbers.  COUNTER is the same as DERIVE, but it won't allow for negative numbers.  ABSOLUTE will reset the previous number to 0 and then divide the curent number by the step.
 
DERIVE ABSOLUTE and COUNTER are reates of change.  GAUGE will give the actual number.  From your previuos post it seemed that you wanted to compare to previous values, but now it seems you just want the actual number.  Use GAUGE for the actual number.
 
Hope that helps
