Hi Robert,
Thanks! Does it mean that in ODL, the only way to get statistics from
physical nodes is through the openflow protocol? I would expect a
statistic-manager capable of collecting statistics from the different
SB plug-ins. That statistic-manager would expose those numbers to
applications abstracting the specifics of the SB protocols.
Unfortunately doing that would require a common model of how statistics
are propagated, and it turns out this is something which varies between
SB protocols -- for example in stateful PCEP the NE pushes state towards
the controller. Hence the responsibility for maintaining these is with
the SB protocols, which are expected to populate inventory/topology
nodes in the data store with these -- and applications can pick them up
from there (via DataTreeChangeListeners) and not worry about how exactly
they get there.
Bye,
Robert
