   Hi @wayuki, Can you try this statement in the 5.3.1 version, this issue seems to be resolved
   ```sql
   CREATE DB_DISCOVERY RULE db_discovery_group_0 (
   STORAGE_UNITS(ds_a, ds_b, ds_c),
   TYPE(NAME='MySQL.NORMAL_REPLICATION'),
   HEARTBEAT(PROPERTIES('keep-alive-cron'='0/5 * * * * ?'))
   );
   ```
