Pike Series Release Notes


New Features

  • The reason of the state change is now part of the API as “state_reason” field of the alarm object.

Deprecation Notes

  • 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: gnocchi_resources_threshold, gnocchi_aggregation_by_metrics_threshold, or gnocchi_aggregation_by_resources_threshold.

  • The deprecated combination alarms support have been removed.

Bug Fixes

  • 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.
