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.

Hth,

Jan.

What's wrong ?

When i use these values in GETIF they return the right results.
