QPS (Query per second) （每秒查询量）
TPS(Transaction per second) （每秒事务量，如果是InnoDB会显示，没有InnoDB就不会显示）
1 计算方法
___________________________________________________________
QPS
Questions = SHOW GLOBAL STATUS LIKE \'Questions\';
Uptime = SHOW GLOBAL STATUS LIKE \'Uptime\';
QPS=Questions/Uptime
TPS
Com_commit = SHOW GLOBAL STATUS LIKE \'Com_commit\';
Com_rollback = SHOW GLOBAL STATUS LIKE \'Com_rollback\';
Uptime = SHOW GLOBAL STATUS LIKE \'Uptime\';
TPS=(Com_commit + Com_rollback)/Uptime
2 第二种计算方法
QPS
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;
TPS
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;
