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

• triaged or confirmed bugs
• Gnocchi
  • gate
  • client
  • indexer sharding support
  • dispatcher optimisation (batching) (in reviews https://review.openstack.org/#/c/202589/ and https://review.openstack.org/#/c/202507/)
  • revisit gnocchi resource definition (dispatcher side: https://review.openstack.org/#/c/202500/)
  • benchmark
• Alarms (Aodh)
  • Devstack plugin (done: https://review.openstack.org/#/c/200467/10/)
  • Devstack gate
• in-tree functional tests
  • add mysql/postgres functional gate
  • add elasticsearch functional gate
  • performance rally tests
• Code Refactoring
  • Split - split polling (M* cycle) https://etherpad.openstack.org/p/ceilometer-collection-split
  • Removal - remove deprecated alarm code (M* cycle) https://etherpad.openstack.org/p/aodh-future
• Polling schema - separate polling logic from pipeline
• Rolling upgrades - queue based schema routing

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.
• Nova
  • the end of nova polling (http://lists.openstack.org/pipermail/openstack-dev/2015-June/067589.html)
  • nova cell metrics
  • nova availability zone metrics
• batching support for recording of event and meter data
• project level pipeline control. enable ability to poll at different frequencies per project.
• granular ttl control (project level / meter level)
• CADF event indexer - generic definition to index all CADF events
• stop using WSME in ceilometer and aodh
• Release to PyPI
• Use specific configuration to load selected stevedore extensions, not all of them
  • remove stevedore plugins out of tree
• Cache everything everywhere, all the time
  • in particular dogpile.cache (because it is already used in Keystone) in the gnocchi dispatcher in ceilometer to cache resources (see POC)
• Add more complete evaluation of the upgrade process in the grenade plugin.
• Notification and pollster driven functional/integration tests.
