Milad Jahandideh's questions

For Example, I have 3 Compute servers and I want to have 1 Specific Instance on each of them and I want to have Node Affinity on them.

• instance_1 --> compute_node_1 (Always on this node)
• instance_2 --> compute_node_2 (Always on this node)
• instance_3 --> compute_node_3 (Always on this node)

I know there is a "Senlin" service. But how to use it exactly? Or if there is another solution?

Is there any command-line tool for the OVN Cluster Health check? Or each of its components? and a command or commands which gives stats about the cluster.

For example, without a functional test, I want to know if everything works properly in our OVN Cluster which has deployed with Kolla-Ansible.

All OVSDBs and OVN-NB-DBs and OVN-SB-DBs are healthy or not?, all Daemons are healthy or not?
