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）
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)/SecondsQPS
mysqladmin -h192.168.160.100 -uroot -p extended-status --relative --sleep=1|grep -w Questions TPS :下面两个值相加
Com_commit=mysqladmin -h192.168.160.100 -uroot -p extended-status --relative --sleep=1|grep -w Com_commit Com_rollback=mysqladmin -h192.168.160.100 -uroot -p extended-status --relative --sleep=1|grep -w Com_rollback TPS = $Com_commit + $Com_rollback统计QPS、TPS的脚本
