wow, thank you for replying. The question is Why does this query appear? I hope only business logic queries.

Can you clarify this please, it's not really clear what you mean.

Can you see the picture that I upload? The fact that I only have one sql that is 'SELECT service_name serviceName, group_name groupName, wave_key waveKey, wave_value waveValue
FROM t_prism_service_alert
WHERE service_name IN(?)' . But the agent report the sql in the picture, I do not know the sql in the picture where is from, because I have not this sql.

I've found the reason. The mysql-connector-java is will to load server properties when it connects or re-connect the mysql server. Load server properties is to send the sql that is in the picture.
