mysql显示innodb状态输出

Question

i am trying to view the buffer pool and row stats that is usually shown when running SHOW INNODB STATUS .

But for some reason this infomation is not being displayed, just lots of record locks. Does anyone now how to view the buffer pool infomation?

Update

After reading the MySQL docs again, i noticed this:

InnoDB Monitor output is limited to 64,000 bytes when produced using 
the SHOW ENGINE INNODB STATUS statement. This limit does not apply to 
output written to the server's error output.

Answer I found the answer i was looking for,

Also how to clear the deadlocks here: How to deliberately cause a deadlock in MySQL

Thanks

Answer 3

MySQL does not have the InnoDB Buffer Pool in its INFORMATION_SCHEMA database

Interesting, XtraDB (used in MariaDB and Percona Server) does have INFORMATION_SCHEMA.INNODB_BUFFER_POOL_PAGES.

If you really need to see the InnoDB Buffer Pool, switch to MariaDB or Percona Server.

运行这个：

show global status like 'innodb_buffer_pool%';
