+All the metadata store metrics are labeled with the following labels:
 
 - *cluster*: `cluster=${pulsar_cluster}`. `${pulsar_cluster}` is the cluster name that you configured in `broker.conf`.
 - *name*: `name=${metadata-store|configuration-metadata-store|state-metadata-store}`. `${name}` is the metadata store name.
