Current Series Release Notes

12.0.0-42

Prelude

Added new tool ceilometer-status upgrade check.

New Features

  • Add availability_zone attribute to gnocchi instance resources. Populates this attribute by consuming instance.create.end events.

  • New framework for ceilometer-status upgrade check command is added. This framework allows adding various checks which can be run before a Ceilometer upgrade to ensure if the upgrade can be performed safely.

Upgrade Notes

  • To take advantage of this new feature you will need to update your gnocchi_resources.yaml file. See the example file for an example. You will need to ensure all required attributes of an instance are specified in the event_attributes.

  • Operator can now use new CLI tool ceilometer-status upgrade check to check if Ceilometer deployment can be safely upgraded from N-1 to N release.

  • Remove deprecated option meter_definitions_cfg_file, use meter_definitions_dirs to configure meter notification file.

  • The following commands are no longer required to be listed in your rootwrap configuration: ipmitool.

Security Issues

  • Privsep transitions. Ceilometer is transitioning from using the older style rootwrap privilege escalation path to the new style Oslo privsep path. This should improve performance and security of Ceilometer in the long term.

  • Privsep daemons are now started by Ceilometer when required. These daemons can be started via rootwrap if required. rootwrap configs therefore need to be updated to include new privsep daemon invocations.
