Hi guys,
Can you think of Openstack (any of its services) administration tasks that cannot be done in HORIZON, but only in CLI:
(Not including external services like HA, Backup...)

Thanks @dbaxps for the reply. Indeed any additonal (though crucial) tasks like HA of OpenStack services are to be done outside of Horizon. What I meant is among usual service tasks. (edited the question for more clarity)
