mysql qps tps计算

Information from web

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;
