篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了MYSQL 8 上云 performance_schema 里面参数我们打开了那些 5个表调整脚本？(POLARDB 适用)相关的知识，希望对你有一定的参考价值。

MYSQL

关于监控如果上云后，到底还需要自行进行监控吗，是一个问题，是否把所有的数据库监控都放到云上，通过云来获取数据库的信息是一个问题。

首先回答是否定的，

1 云的数据库监控的数据，部分也是通过数据库中的系统的表中获得的

2 云的监控数据的需要进行处理加工，处理加工的方式对不对，这也是一个问题

3 更细致的监控，举例如果是POSTGRESQL 那么云的监控给出的数据是可怜的，必然我们要通过PG 里面的详细的系统表进行数据的获得和更细化的信息的获得，mysql 8 也是一致的

所以结论是，必须要打开 PS ( performance_schema) ,并从中获得系统的信息。

show variables like performance_schema;

MYSQL

首先需要先熟悉下面的五个表，这是针对PS的开关，具体PS 如何使用，怎么使用，性能消耗，都和这五个设计的表有关

1 setup_instruments

这个参数至关重要，他对所有的监控项进行了设置，其中1236 个选项中

MYSQL

打开的参数有544 个（8.027 ），这些参数中是否都需要打开，显然粗略的看一看就知道，不需要，所以下面总结了将目前我们任务无用的监控设置关闭的语句

下面是组织好的语句，针对MYSQL 8 performance_schema 中的setup_instruments 中的获取的嬉戏进行关闭，下面的是默认开启，但实际上我们并不使用的仪器。实际上我们使用的打开的
