Ocata Series Release Notes


Bug Fixes

  • Install python-redis if the coordination backend url is redis. This is an indirect dependency on evaluator coordination to work.


New Features

  • Add new parameter “control_exchange”, the default exchange under which topics are scoped. May be overridden by an exchange name specified in the transport_url option.

  • Add new parameter “rpc_response_timeout”, seconds to wait for a response from a call

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

Upgrade Notes

  • The Ubuntu packages for Ocata use a different location for the app.wsgi file and as such the default has been updated. If planning on using the Ocata modules with older versions of the package, be aware you may need to specify a different app.wsgi location

Deprecation Notes

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

Bug Fixes

  • Updated app.wsgi location from /usr/share/aodh-common/app.wsgi to the new location at /usr/share/aodh/app.wsgi



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.

Deprecation Notes
