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.
- Version of OpenStack
- 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 in Measurements.
- Nova with libvirt only
- Most of the Nova meters will only work with libvirt fronted hypervisors at the
moment, and our test coverage was mostly done on KVM. Contributors are welcome
to implement other virtualization backends’ meters.
- Quantum delete events
- 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.
- Database backend
- 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.
- Volume of data
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.
