The vm-state-notification stream has the following details:

  • cluster_name: the cluster holds KVM nodes

  • node_name: KVM node name

  • vm_name: UPF name

  • state: VM state

  • message: Carries useful information such as error message or mgmt-ip when the state of the VM is ALIVE.

Depending on the life cycle stage of the VM, notifications are generated from either the Cluster Manager or CEE Ops-Center and sent to the NSO.

All other notifications are generated by the Alert Manager and then sent to the CEE Ops-Center notification stream.
