Pike Series Release Notes¶
The reason of the state change is now part of the API as “state_reason” field of the alarm object.
Ceilometer’s API is deprecated in Ocata. Therefore, threshold alarms are now deprecated as well. Threshold rules will be removed when Ceilometer’s API is also removed. Similar functionality is provided through Gnocchi alarm rules:
The deprecated combination alarms support have been removed.
When an unprivileged user want to access to Gnocchi resources created by Ceilometer, that doesn’t work because the filter scope the Gnocchi query to resource owner to the user. To fix we introduce a new configuration option “gnocchi_external_project_owner” set by default to “service”. The new filter now allow two kind of Gnocchi resources:
owned by the user project
owned by “gnocchi_external_project_owner” and the original project_id of the resource is the user project.
