############### 24 October 2025 ############### ****************************** Catalyst Cloud Metrics Service ****************************** We have launched the new Catalyst Cloud Metrics Service, in open beta. The Metrics Service increases the observability of your resources running in the cloud by exposing a number of useful metrics. With its comprehensive query API you can monitor your cloud resources, and get time-series data suitable for making dashboards. Along with metrics, a history of the state of resources is also kept for up to 90 days (with decreasing granularity), allowing a look into historical data in addition to monitoring the current state of resources. The Metrics Service is free to use for all Catalyst Cloud customers. To find out more, see :ref:`Catalyst Cloud Metrics Service `. ****** Alarms ****** The Catalyst Cloud Alarm Service now uses the Metrics Service as the source for resource metrics. Threshold alarms monitoring resource metrics can be created using the ``gnocchi_resources_threshold`` and ``gnocchi_aggregation_by_resources_threshold`` alarm types. For more information, see the documentation for the :ref:`Catalyst Cloud Alarm Service `. ************* Orchestration ************* When configuring auto-scaling with the :ref:`Catalyst Cloud Orchestration Service `, alarms are now configured using one of the types backed by the Metrics Service listed above. For more information, see the documentation for :ref:`auto-scaling with the Catalyst Cloud Orchestration Service `. .. note:: These changes do not apply to :ref:`Catalyst Cloud Kubernetes Service (CCKS) ` clusters running Kubernetes v1.28 and later, as newer clusters use a different mechanism for auto-scaling. If you have any CCKS clusters running Kubernetes v1.27 or earlier, please consider :ref:`rebuilding your cluster ` to upgrade to the latest version of Kubernetes and ensure your workloads continue working correctly.
