Ocata Series Release Notes


Bug Fixes

  • Expose metric processing delay param.


Bug Fixes

  • Install redis when coordination is set in gnocchi storage. Otherwise metricd will go creazy and throw exceptions.


Deprecation Notes

  • The Gnocchi API options host, port and workers are deprecated. These options have been removed in the Gnocchi project so they have no effect whatsoever.

  • Remove api-paste configuration as its now moved into the python code. There is no need to explicitly configure it.


New Features

  • Passes parameter to keystone authtoken define to manage python-memcache package install.

Deprecation Notes

  • signing_dir option is now deprecated for removal, the parameter has no effect.



Add hooks for external install & svc management.

New Features

  • This adds defined anchor points for external modules to hook into the software install, config and service dependency chain. This allows external modules to manage software installation (virtualenv, containers, etc) and service management (pacemaker) without needing rely on resources that may change or be renamed.


New Features

  • This adds the enable_proxy_headers parsing option which is used by the http_proxy_to_wsgi middleware.
