A new feature in OSP8 enables Ceilometer to store events in both the undercloud and overcloud. This feature needs to be documented so users know how to enable it. The gist of the documentation needed is as follows: Undercloud ---------- Before running 'openstack undercloud install', edit 'undercloud.conf' by setting 'store_events' to 'true'. Overcloud --------- Create an additional environment file called 'ceilometer.yaml' that has the following contents: parameter_defaults: CeilometerStoreEvents: true Add this environment file to the overcloud deploy command. For example: openstack overcloud deploy --templates -e ~/ceilometer.yaml
