Found this note in the quantum notification code, think it is worth being in the release notes. Change-Id: I6e30d47e1f50fb0f7fda6e0923d5836a2b133110
2.1 KiB
Version 0.1 (Folsom)
This is the first release of ceilometer. Please take all appropriate caution in using it, as it is a technology preview at this time.
It is curently tested to work with OpenStack 2012.2 Folsom. Due to its use of openstack-common, and the modification that were made in term of notification to many other components (glance, cinder, quantum), it will not easily work with any prior version of OpenStack.
Currently covered components are: Nova, Nova-network, Glance, Cinder and Quantum. Notably, there is no support yet for Swift and it was decided not to support nova-volume in favor of Cinder. A detailed list of meters covered per component can be found at: xxxx
Quantum delete notifications do not include the same metadata as the other messages, so we ignore them for now. This isn't ideal, since it may mean we miss charging for some amount of time, but it is better than throwing away the existing metadata for a resource when it is deleted.
The only tested and complete database backend is currently MongoDB, the SQLAlchemy one is still work in progress.
The current best source of information on how to deploy this project is found as the devstack implementation but feel free to come to #openstack-metering on freenode for more info.
Please note that metering can generate lots of data very quickly. Have a look at the following spreadsheet to evaluate what you will end up with. http://wiki.openstack.org/EfficientMetering#Volume_of_data
