Sebastiaan, Most oid's are followed by an index number. With this index number you can distinguish between several items within the same catagory (cpu's, interfaces etc.). Even with only one cpu in the target this index number is needed.
This indexnumber (usualy a 0 or a 1) can be found with getif: In the wide result window of Getif select the item you want to monitor with mrtg. In the bottom left box you will get the complete oid that you can use in MRTG.
