Description Yurii Prokulevych 2015-11-19 08:24:59 UTC 
Description of problem:
python-redis is required by openstack-polling services to run.
Right now it's not installed with director.

Actual results:
Traceback in log. 

Expected results:
python-redis is installed
Comment 2 Jaromir Coufal 2015-11-25 17:13:56 UTC 
Eoghan, would you consider this as a dependency for ceilometer?

If it is optional dependency only, it requires additional work in director (disk-image-builder at least) and this would probably miss OSP8 release.
Comment 3 Eoghan Glynn 2015-12-08 11:18:38 UTC 
Jaromir, yes python-redis is a dependency of tooz in the mode in which we recommend tooz is used for coordination between ceilometer central agents.

Without tooz, then the central agent cannot be run in active/active mode.
Comment 6 Yurii Prokulevych 2016-03-16 15:10:07 UTC 
Verified with openstack-tripleo-puppet-elements-0.0.4-1.el7ost.noarch.
python-redis is installed and ceilometer-central is running on controllers.
