I have a several Netapp storage backup processes that give a "last total transferred" as an SNMP value. This number changes once the next backup process is completed. I pull this value using PRTG and while it records the value as "Volume", it calculates a proposed "Speed" and displays the speed on the graph (not the volume which is the number that I need).

For example: If I have a backup that transfers 2,111MB, at the end the SNMP value changes to 2111. With a 30sec scheduled interval, PRTG calculates a 70MB/s transfer rate and displays that on the graph. Essentially, the graph is wrong because that's not the actual speed, nor is it the value I want displayed.

I also have some custom sensors that are referring to these channels to sum all backup transfers which obviously are wrong too.

How do I get the correct value displayed on the graph? Is it a specific Unit configuration that is needed and if so, what unit?

Can you post a screenshot of the sensor configuration and its overview page?

Sure, here's screenshots of Config, Live, and Overview (below).

The last report was 1750MB transfer in which its speed was calculated as 58 #/s (using 30sec intervals - 1750/30sec = 58.3). But its the total transfer I need graphed, not the assumed speed.

That has to be done in the MIB file itself...could you upload it somewhere?
