Pike Series Release Notes¶
Adds the kombu_failover_strategy option for configuring oslo.messaging.rabbit. This will determines how the next RabbitMQ node is chosen in case the one we are currently connected to becomes unavailable.
Add openstack-db tag to Exec that run db-sync.
Add parameter to apacher_wsgi to allow overwrite and/or add additional wsgi process options.
Add cpu_l3_cache meter in polling yaml for cache monitoring feature to work out of the box.
Add support to override host param in ceilometer config. Without this sometimes fqdn wont match and some nova metrics will be skipped.
ceilometer::rpc_backend is deprecated and will be removed in a future release. Please use ceilometer::default_transport_url instead.
Deprecated keystone authtoken signing_dir option is removed in Pike.
Deprecate store_events option. This option has been removed from ceilometer since Newton.
When ceilometer::expirer::enable_cron is set to False, Puppet will try to remove the crontab. It’s useful when you upgrade from Ocata to Pike and you want the crontab to be removed (the service is deprecated).
Deprecate ceilometer::client as api is deprecated. Instead use gnocchi, aodh and panko clients directly to query data.
memcached_servers option is now deprecated and will be removed in the future release, please use memcache_servers instead.
Add ability to configure pipeline yaml publishers. The default is gnocchi. If you are using collector, override this param to publisher:// instead.
Add new parameter “notification_driver”, driver or drivers to handle sending notifications. Value can be a string or a list.
Ceilometer collector is deprecated in pike release. Configure the publisher directly instead to decide where the data should be sent in pipeline.yaml. For example, set publisher to gnocchi:// to send the data from ceilometer to gnocchi and bypass collector completely.
meter_dispatcher and event_dispatcher options are now deprecated, please use meter_dispatchers and event_dispatchers options instead.
url option of ceilometer::dispatcher::gnocchi is now deprecated for removal, the parameter has no effect.
Fix dispatcher params to not convert the array into string. This way its compatible with service defaults.
Replace ceilometer dbsync with upgrade command. dbsync has been deprecated. Also remove the skip gnocchi opts as gnocchi is default now.
Update the default event publisher to be gnocchi://. This is the default upstream.
Switch meter_dispatchers and event_dispatchers parameters to $::os_service_default fact.
