Project Mission

To reliably collect measurements of the utilization of the physical and virtual resources comprising deployed clouds, persist these data for subsequent retrieval and analysis, and trigger actions when defined criteria are met.

Road Map

Current (Liberty) Cycle Targets: https://blueprints.launchpad.net/ceilometer/liberty

Priority Work Items

The following are high priority items targeted for the current cycle that require owners:

  • document operator changes from alarm in Ceilometer to alarm in Aodh
    • to be followed by email to operators list

Open Work Items

The following is a list of work items that have been approved conceptually and can be targeted for the current development cycle. For more information on a item, contact us on openstack-dev mailing list or on freenode at #openstack-ceilometer. The current list of core contributors are: https://launchpad.net/~ceilometer-drivers/+members#active

Future Targets

These ideas have been discussed/introduced at a high-level. They are areas of interests for the users/developers of Ceilometer but still require discussion. Proposals for concrete work items related to these items are welcomed for future cycles:

  • log processing
  • application level monitoring
  • project defined meters - leveraging declarative meters
  • group based configuration control - connect tooz to manage configuration and allow for better control of configuration updates.
  • the end of nova polling (http://lists.openstack.org/pipermail/openstack-dev/2015-June/067589.html)
  • batching support for recording of event and meter data
  • granular ttl control (project level / meter level)
  • CADF event indexer - generic definition to index all CADF events
