Suppose we've defined a SNMP agent Item to collect ifInOctets of some an Interface. As you know, this is an accumlated value, is it possible to define a customer graph to represent its change(Latest - Last)?
...an accumulated value???
Does that mean that your graph/values just goes up, up, up, etc.?
Are you using Template_SNMPv2_Device by any chance?
If the item is defined correctly, the graphs will give you Latest - Last. Graphs that look like graphs, you know, up, up more, down, up, down, . . .

Thank you, MrKen.
Now I know the attribute 'store value' of an item should be set as delta. Then I can get a graph which looks like up,down,up...
Actually the manual had clearly introduced it, but I missed. :(
