Ussuri Series Release Notes

New Features

  • The service setup in keystone for ceilometer will now be executed through delegation to the ceilometer_service_setup_host which, by default, is localhost (the deploy host). Deployers can opt to rather change this to the utility container by implementing the following override in user_variables.yml.

    ceilometer_service_setup_host: "{{ groups['utility_all'][0] }}"
  • The role now supports using the distribution packages for the OpenStack services instead of the pip ones. This feature is disabled by default and can be enabled by simply setting the ceilometer_install_method variable to distro.

  • Support separate oslo.messaging services for RPC and Notifications to enable operation of separate and different messaging backend servers in ceilometer.

Upgrade Notes

  • The variables ceilometer_oslomsg_rpc_servers and ceilometer_oslomsg_notify_servers have been removed in favour of using ceilometer_oslomsg_rpc_host_group and ceilometer_oslomsg_notify_host_group instead.

  • Due to the smart-reources implementation, variables, related to custom git path of exact config files were removed. Now all config files are taken from upstream git repo, but overrides and client configs are still supported. The following variables are not supported now: * ceilometer_git_config_lookup_location * ceilometer_data_meters_git_file_path * ceilometer_event_definitions_git_file_path * ceilometer_gnocchi_resources_git_file_path * ceilometer_loadbalancer_v2_meter_definitions_git_file_path * ceilometer_osprofiler_event_definitions_git_file_path * ceilometer_polling_git_file_path If you are maintaining custom ceilometer git repository, you still may use ceilometer_git_repo variable, to provide url to your git repository.

Deprecation Notes

  • The following variables are no longer used and have therefore been removed.

    • ceilometer_requires_pip_packages

    • ceilometer_service_name

    • ceilometer_service_port

    • ceilometer_service_proto

    • ceilometer_service_type

    • ceilometer_service_description

  • The log path, /var/log/ceilometer is no longer used to capture service logs. All logging for the ceilometer service will now be sent directly to the systemd journal.

  • The rabbitmq server parameters have been replaced by corresponding oslo.messaging RPC and Notify parameters in order to abstract the messaging service from the actual backend server deployment. - ceilometer_oslomsg_rpc_servers replaces rabbitmq_servers - ceilometer_oslomsg_rpc_port replaces rabbitmq_port - ceilometer_oslomsg_rpc_userid replaces ceilometer_rabbitmq_userid - ceilometer_oslomsg_rpc_vhost replaces ceilometer_rabbitmq_vhost - added ceilometer_oslomsg_rpc_use_ssl - added ceilometer_oslomsg_notify_servers - added ceilometer_oslomsg_notify_port - added ceilometer_oslomsg_notify_use_ssl - added ceilometer_oslomsg_notify_userid - added ceilometer_oslomsg_notify_vhost - added ceilometer_oslomsg_notify_password

Bug Fixes

  • ceilometer-polling services running on compute nodes did not have the polling namespace configured. Because of this they used the default value of running all pollsters from the central and compute namespaces. But the pollsters from the central namespace don’t have to run on every compute node. This is fixed by only running the compute pollsters on compute nodes.
