One of the options you can set is:
Log unknown data as zero instead of the default behaviour of repeating
the last value seen. Be careful with this, often a flat line in the graph
is much more obvious than a line at 0.

Your interface order may be different, but the way you are referencing
them in the target is for example 2:community at localhost, so its looking
for the second interface which may now not be the same as when you set it
If you look at the reference page I linked above, there are different ways
to reference the interface. You can do it by IP, MAC, description and
a few others. That might help you get a more static reference to the
relevant card your trying to measure.
