[ovirt-users] metrics

Hi, I'm trying to configure oVirt metrics but when i run # ANSIBLE_LOG_PATH=/tmp/ansible.log ansible-playbook -vvv -e @/root/vars.yaml -i /root/ansible-inventory-origin-39-aio playbooks/deploy_cluster.yml i always get this error: Failure summary: 1. Hosts: localhost Play: Verify Requirements Task: Validate openshift_node_groups and openshift_node_group_name Message: last_checked_host: localhost, last_checked_var: openshift_node_group_name;openshift_node_group_name must be defined for all nodes What am I missing here?
