However, this functionality was deprecated -in Newton and removed in Ocata. Event storage and querying functionality -is now provided by a service called Panko. Use-cases of historical -event data storage include audit logging, debugging and billing. - -Problem Description -=================== - -Panko is an event storage service that provides an ability to store and -query event data generated by Ceilometer with potentially other sources. -Panko includes support for several storage options (sqlalchemy-compatible -databases, mongodb, elasticsearch) which differ in their level of maturity. - -At its core Panko is a regular API service with a database backend. - -Events are published to Panko via Direct publisher in Ocata while in -Pike Direct publisher was deprecated and will be removed. For that -reason Panko publisher was added. - -* Direct publisher `deprecation `__ (ceilometer/publisher/direct.py) was done under this `commit `__. - -Another mechanism that was deprecated in Pike is dispatchers which were -used to send data specified by publishers. So were -{event,meter}_dispatchers options in ceilometer.conf - -* Panko dispatcher `deprecation `__. -* `Notes `__ on unneeded duplication of publishers and dispatchers. -* A `discussion `__ on dispatchers vs publishers. - -This is instead done directly by publishers in Pike and Panko publisher is -present in Panko's repository itself, not ceilometer repository. - -Panko first appeared in Ocata Ubuntu Cloud Archive. - -Ceilometer is able to query Panko's presence via Keystone catalog but -does not define a publisher for sending event data to Panko by default. - -Proposed Change -=============== - -The new charm should include the following features: - -- Support SQLAlchemy-compatible databases as storage backends; -- HA support; -- TLS support; -- integration with Ceilometer charm. - -Alternatives ------------- - -None for historical event data within OpenStack. - -Implementation -============== - -Assignee(s) ------------ - -Primary assignee: - dmitriis - -Gerrit Topic ------------- - -Use Gerrit topic "panko-charm" for all patches related to this spec. - -.. code-block:: bash - - git-review -t panko-charm - -Work Items ----------- - -Reactive Interfaces -+++++++++++++++++++ - -- interface: panko - -Provide Panko charm -+++++++++++++++++++++ - -- Create a charm layer based on openstack-api layer; -- Add support for upgrading Panko (schema changes); -- Add support for deploying Panko in a highly available configuration; -- Add support for the Panko to display workload status; -- Add support TLS endpoints; -- Charm should have unit and functional tests. - -Update Ceilometer Charm -+++++++++++++++++++++++++++++++++ - -- Support for deployment with Panko (by specifying publishers correctly - in event_pipeline.yaml for both Ocata and Pike+). - -Mojo specification deploying and testing Panko -++++++++++++++++++++++++++++++++++++++++++++++++ - -- Update HA Mojo spec for deploying Panko in an HA configuration. - -Update telemetry bundle -+++++++++++++++++++++++ - -- Update telemetry bundle to deploy Panko - -Repositories ------------- - -A new git repository will be required for the Panko charm: - -.. code-block:: bash - - https://git.openstack.org/openstack/charm-panko - -Documentation -------------- - -The Panko charm should contain a README with instructions on deploying the -charm.
