module: ovirt_event_facts
short_description: This module can be used to retrieve information about one or more oVirt/RHV events
author: "Chris Keller (@nasx)"
deprecated:
    removed_in: 3.0.0  # was Ansible 2.13
    why: When migrating to collection we decided to use only _info modules.
    alternative: Use M(ovirt.ovirt.ovirt_event_info) instead.
