Two angles to that:
- the utilisation
- the data available

Utilisation:
- During the last APM meeting, APMs have mentioned about their interests 
for interface input errors.

Data available:
- what data can be easily collected and fed to the MA? Are the NRENs 
already storing interface input errors so that we can make direct use of 
them?
- What tool can be used to populate those data?
- Are there NRENs ready to extend the data collection or their RRD tools?

For GEANT, we do not collect input errors, but we could do. We currently 
collect interface output drops per type of service (PiP, BE, LBE).
