关于MySQL的TPS和QPS

计算方法：

TPS = (COM_COMMIT + COM_ROLLBACK)/UPTIME

use information_schema;
select VARIABLE_VALUE into @num_com from GLOBAL_STATUS where VARIABLE_NAME ='COM_COMMIT';
select VARIABLE_VALUE into @num_roll from GLOBAL_STATUS where VARIABLE_NAME ='COM_ROLLBACK';
select VARIABLE_VALUE into @uptime from GLOBAL_STATUS where VARIABLE_NAME ='UPTIME';
select (@num_com+@num_roll)/@uptime;

QPS - Queries Per Second（每秒查询处理量）同时适用与InnoDB和MyISAM 引擎 

计算方法：

QPS=QUESTIONS/UPTIME

use information_schema;
select VARIABLE_VALUE into @num_queries from GLOBAL_STATUS where VARIABLE_NAME ='QUESTIONS';
select VARIABLE_VALUE into @uptime from GLOBAL_STATUS where VARIABLE_NAME ='UPTIME';
select @num_queries/@uptime;
