mysql计算实时的QPS/TPS
版本:mysql 5.7
需要开启show_compatibility_56
mysql> set global show_compatibility_56=on;
Query OK, 0 rows affected (0.00 sec)
mysql> show variables like '%show_compatibility_56%';
+-----------------------+-------+
| Variable_name | Value |
+-----------------------+-------+
| show_compatibility_56 | ON |
+-----------------------+-------+
1 row in set (0.01 sec)
QPS:
select VARIABLE_VALUE,now() from information_schema.GLOBAL_STATUS where VARIABLE_NAME in ('Queries');
查询两次得到的差值除以时间间隔
TPS:
select
sum(`VARIABLE_VALUE`),
now()
from
information_schema.GLOBAL_STATUS
where
VARIABLE_NAME in (
'COM_COMMIT',
'COM_ROLLBACK',
'COM_INSERT',
'COM_DELETE',
'COM_UPDATE'
)
