hi all,

as you may have heard, in an effort to simplify OpenStack Telemetry 
(Ceilometer) and streamline it's code, the alarming functionality 
provided by OpenStack Telemetry has been moved to it's own 
repository[1]. The new project is called Aodh[2]. the idea is that Aodh 
will grow as it's own entity, with it's own distinct core team, under 
the Telemetry umbrella. this way, we will have a focused team 
specifically for the alarming aspects of Telemetry. as always, feedback 
and contributions are welcomed[3].

in the coming days, we will release a migration/changes document to 
explain the differences between the original alarming code and Aodh. all 
effort was made to maintain compatibility in configurations such that it 
should be possible to take the existing configuration and reuse it for 
Aodh deployment.

some quick notes:
- the existing alarming code will remain consumable for Liberty release 
(but in deprecated state)
- all new functionality (ie. inline/streaming alarm evaluations) will be 
added only to Aodh
- client and api support has been added to common Ceilometer interfaces 
such that if Aodh is enabled, the client can still be used and redirect 
to Aodh.
- mailing list items can be tagged with [aodh]
- irc discussions will remain under #openstack-ceilometer

many thanks for all those who worked on the code split and integration
