The vm_instance value in the ceilometer_cpu metric is showing the server hostname (fqdn) while it should show the nova hostId.
Steps to reproduce the behavior:
- Deploy RHOSO (18.0.11-trunk-20250722.1) with telemetry enabled (osasinfra DT)
- Deploy VMs on top (or shift-on-stack installation)
- Get ceilometer_cpu metric
- Check the vm_instance value for each metric result

Expected behavior
The vm_instance param in the ceilometer_cpu metric was showing the server hostId before, which is available for non-admin users.
Additional context
- This metric is being tested as part of the RHOSO and shift-on-stack correlated query epic documented at https://github.com/openshift/installer/blob/main/docs/user/openstack/observability.md where the correlated query:
sum by (vm_instance) (
group by (vm_instance, resource) (ceilometer_cpu)
/ on (resource) group_right(vm_instance) (
group by (node, resource) (
label_replace(kube_node_info, "resource", "$1", "system_uuid", "(.+)")
)
/ on (node) group_left group by (node) (
cluster:master_nodes
)
)
)
retrieves the ceilometer_cpu metric and the result of the query is contrasted with the info obtained from Openstack.
