Xena Series Release Notes


New Features

  • The new aodh::logging::watch_log_file parameter has been added.

  • Adds new purge_config parameter. When set to true, the policy file is cleared during configuration process. This allows to remove any existing rules before applying them or clean the file when all policies got removed.


New Features

  • Added alarm_histories_delete_batch_size parameter to the expire class to enable configuration of the parameter with the same name. It allows limiting number of alarm histories purged by a single purge run.

  • The new aodh::coordination class has been added.

  • The new aodh::cors class has been added.

Upgrade Notes

  • The aodh::evaluator class no longer adjust workers based on the coordination_url parameter. Please set the corrdination backend if multiple workers are used.

  • Fedora is no longer supported.

Deprecation Notes

  • The aodh::evaluator::coordination_url parameter has been deprecated in favor of the new aodh::coordination class.


New Features

  • The new aodh::api::gnocchi_external_domain_name parameter has been added.

  • The following two parameters have been added to the aodh::notifier class.

    • batch_size

    • batch_timeout

  • There is now a new policy_dirs parameter in the aodh::policy class, so one can set a custom path.

  • A new class aodh::wsgi::uwsgi exist to allow configuring uwsgi in operating systems that support this (ie: currently Debian). This helps configuring the number of processes, threads and listen socket. Also, a new aodh_api_wsgi_config provider now exist.

Upgrade Notes

  • The aodh::api class no longer supports standalone api service in CentOS and Ubuntu, because these 2 distros don’t provide standalone api service and require that wsgi is used to run the api service.
