Postgres cluster_name parameter in percona mysql

Hello Everyone

Do we have any parameter that can be identified or tagged a single/group of servers, like the cluster_name parameter in PostgreSQL.

I understand that we have something like “wsrep_cluster_name” on Percona Xtradb cluster with Galera:

I could not find anything similar on Percona Server MySQL distributions.

If not, can someone share an option/idea on how can I classify mysql instances based on service name or cluster names for all single instances / primary-standby instances and Multi-Master instances.
