Description

By default we have pool metrics like this:

ceph_pool_objects{pool_id="1"} 1075534
ceph_pool_metadata{name="name_of_pool_1",pool_id="1"} 0

When I was try to join 'name' label from metadata series (to use label with Grafana) like this:

ceph_pool_objects * on (pool_id) group_left(name) ceph_pool_metadata

Result returned without metric, only labels:

{name="name_of_pool_1",pool_id="1"}

This is because metadata metric always have value '0'.
This behavior will be fixed if set value to '1'.
