BUG?: Units and combination of graphs, by using 'interface' check

Troubleshooting
10

Hi Tom,

for test purposes I´ve add

check_metrics["check_mk-<plugin-name>"] = if_translation

and it works.

It’s illogical for me!

Crazy observation, without this solution:
only “outqlen” from interface-check works even so.

Best, c3po
