Description Takashi Kajinami 2020-04-13 02:22:05 UTC 
Description of problem:

In RHOSP16.0, legacy Telemetry services (ceilometer, gnocchi and panko) are no more deployed by default.
However, we still see Redis is enabled by default, though there are no components using it.

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1. Deploy overcloud with the default templates
2. Check whether redis, redis vip and telemetry services are enabled

Actual results:
Redis and its vip is enabled while telemtry services are disabled

Expected results:
Redis, its vip and temeletry services are all disabled

Additional info:
Comment 7 Takashi Kajinami 2020-04-14 07:28:12 UTC 
I updated bug title because it sounds like an another issue to disable redis vip when redis is disabled.
I think it's better to deal with redis itself in this bug, and address vip in another bz.
Comment 8 Luca Miccini 2021-06-24 08:15:41 UTC 
let's retarget this to 17 and see how to best tackle it.
