Awesome! But where in the source are they? As the only two notification
plugins that seem to exist on the compute agent are for cpu and
instance. Is there meant to be one that handles
network.outgoing/incoming updates on those VM state changes?
On Havana I know those network notifier plugins aren't there, so I
assume master then and possibly going towards icehouse.
I'll have a play with it again, but last time i did a clean devstack off
of master, notification plugins weren't working at all for me. Has
anyone else had this issue?
Sorry for all the questions, just poking at ceilometer and trying to get
data from it that I can be sure I can trust, and use for billing. I
don't mind digging in the source, or even extending/fixing things, just
need to know where to look.
