Do you already have existing rrd files on the server which contain 
utilisation data from eth0 (and are populated e.g. by MRTG)? Then you 
may expose this data via RRD MA.
Or you want to use RRD MA store functionality (see below)?

Sure.

RRD MA is web service which provides two main functions:
- Publishing measurement data: The web service uses existing RRD files 
and provides an interface for users who want to browse such measurement 
data in a standardised manner
- Accepting and writing measurement data: some other services can make 
use RRD MA write functionality (in details they send this 
MeasurementArchiveStoreRequest message to RRD MA) to store measurement 
results in the RRD MA web service. Once stored, those results are 
available through the RRD MA publishing functionality.
