一、通过show status
mysql> show status like 'innodb_buffer_pool_pages_data';
+-------------------------------+---------+
| Variable_name | Value |
+-------------------------------+---------+
| Innodb_buffer_pool_pages_data | 3226366 |
+-------------------------------+---------+
1 row in set (0.00 sec)
mysql> show status like 'innodb_buffer_pool_pages_total';
+--------------------------------+---------+
| Variable_name | Value |
+--------------------------------+---------+
| Innodb_buffer_pool_pages_total | 3244032 |
+--------------------------------+---------+
1 row in set (0.00 sec)
val=innodb_buffer_pool_pages_data/innodb_buffer_pool_pages_total x 100%=3226366/3244032 x 100%=99.46%
二、通过SQL查看
mysql> select * from performance_schema.global_status where variable_name in ('innodb_buffer_pool_pages_data','innodb_buffer_pool_pages_total');
+--------------------------------+----------------+
| VARIABLE_NAME | VARIABLE_VALUE |
+--------------------------------+----------------+
| Innodb_buffer_pool_pages_data | 3226437 |
| Innodb_buffer_pool_pages_total | 3244032 |
+--------------------------------+----------------+
2 rows in set (0.00 sec)
val=innodb_buffer_pool_pages_data/innodb_buffer_pool_pages_total x 100%=3226437/3244032 x 100%=
