> 100)
The rule fires when a MySQL instance that is currently acting as a Galera donor (its wsrep_local_state metric equals 2) also has a replication receive queue larger than 100 (wsrep_local_recv_queue > 100). In that case the alert MySQLGaleraDonorFallingBehind is triggered, indicating the donor is lagging behind.
