从监控告警日志内容可以看出来，是由于函数操作不符合规范造成的MGR集群掉线，具体日志描述如下：

This function has none of DETERMINISTIC, NO SQL, or READS SQL DATA in its declaration and binary logging is enabled (you *mi

ght* want to use the less safe log_bin_trust_function_creators variable) Error_code: 1418

遇到这种问题可以从两个方面去解决。第一种方法就是开发人员按照规范创建符合标准的函数；第二种方法就是配置数据库参数，将log_bin_trust_function_creators配置为开启。

此处，开发人员也是选择了将log_bin_trust_function_creators参数配置为开启，但是在一个节点开启了，其他节点未开启，最终导致其他节点出现上述错误信息。
