ceilometer cli client install help

good afternoon, i have a running kolla-ansible openstack all-in-one cluster, so far so good (zed version based on ubuntu). i have installed ceilometer, and then i am trying to use this command to show metrics, but seems i cannot find the right command option, what am i missing? " (my-virt-env) marcello@mg-ostack-119:~$ openstack metric resource list openstack: 'metric resource list' is not an openstack command. See 'openstack --help'. Did you mean one of these? service create service delete service list service provider create service provider delete service provider list service provider set service provider show service set service show " thank you.
