Hello, what resource optimization do you want to do with watcher? If you just want to save energy, you don't need to pay attention to cpu_usage. If you want to do virtual machine migration or server load balancing, please provide the specific version of the missing cpu_usage, or submit a watcher commit, we will analyze it together, thank you! ---- Replied Message ---- | From | Nguyễn Hữu Khôi<nguyenhuukhoinw@gmail.com> | | Date | 02/15/2023 11:51 | | To | OpenStack Discuss<openstack-discuss@lists.openstack.org> | | Cc | | | Subject | [Watcher] How use Watcher to scheduler Openstack resource without cpu_usage | Hello guys. I want to use watcher to scheduler openstack resources but some openstack versions are missing cpu_usage metric. How do we use Watcher without it? Thank you. Nguyen Huu Khoi
