Hello,

Maybe an easy way it is configuring connection limit or connection rate limit and configure snmp alert when the limit is reached looking for the log entry similar to: 

Warning, connections equals limit 192.168.42.95:55587 -> 20.48.40.20:3306, proto TCP, VS /test/VS_GALERA_3306: Connection limit reached..

Be careful, because once the limit is reached new connections are rejected so my propose is configure connection limit in the pool member.
