perfsonar development work

[Fausto Vetter <>]

Hi Nina,

I corrected the units as you told me (Bps, Dps and Eps) and it worked  
fine. By the way, this service is ready to answer to the following  
event types related to interfaces:

http://ggf.org/ns/nmwg/characteristic/discards/2.0/
http://ggf.org/ns/nmwg/characteristic/errors/2.0/
http://ggf.org/ns/nmwg/characteristic/packets/nonunicast/2.0/
http://ggf.org/ns/nmwg/characteristic/packets/unicast/2.0/
http://ggf.org/ns/nmwg/characteristic/utilization/2.0/
http://ggf.org/ns/nmwg/tools/snmp/2.0/

Respectively the units are:
Dps
Eps
Pps
Pps
Bps
All above

Also, errors and discards are possible to collect in and out. The same  
happens to packets unicast and non-unicast. Do you think it is  
possible to add these features to perfSONAR-UI?

Thanks,
