The Ceilometer team is proud to announce the first synchronous milestone delivery with the OpenStack project. Grizzly-2 is also the last folsom compatible version of Ceilometer as we are planning to introduce some breaking changes very soon in our trunk to enable a totally new set of features bringing Ceilometer beyond basic metering into monitoring and alerting.

With this milestone, 10 blueprints have been implemented and 53 bugs have been fixed. Here is a quick summary of the new features:

Pluging can now be disabled so that they will not be polled when they are not needed.
Removed all nova database access from Ceilometer agents
SQLAlchemy DB driver is now fully implemented
Ceilometer is now provided with a default configuration file
Multi-dimension indexing allows to perform queries that aggregate meters based on additional keypair values other than the simple tenant/user/resource triplet
Ceilometer now provide a user facing API which allows the users to query Ceilometer limiting them to their own data.
Compute agent interaction with hypervisor layer is now independent of nova internals
Their is now a python-ceilometer CLI
Swift is now instrumented and meters therefore accessible
Ceilometer does not neet to use nova.flags and read nova configuration anymore
