/!\ Announce now published as https://launchpad.net/ceilometer/+announcement/11069

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.

This milestone can be found at:


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

  • Plugins 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 provides a user facing API which allows non-admin users to query Ceilometer, limiting them to their own data.
  • Compute agent interaction with hypervisor layer is now independent of nova internals
  • There is now a python-ceilometerclient library and a ceilometer client CLI
  • Swift is now instrumented and meters therefore accessible
  • Ceilometer does not need to use nova.flags nor to read nova configuration anymore
