how to view how much innodb buffer pool size using

They deprecated that status in MySQL 5.5 by the way.
In MySQL 5.5, you should use: SHOW ENGINE INNODB STATUS;

An alternative is:
-- http://dev.mysql.com/doc/refman/5.1/en/show-status.html
-- http://dev.mysql.com/doc/refman/5.1/en/server-status-variables.html
SHOW GLOBAL STATUS LIKE 'Innodb_buffer_pool_pages_total';

The result will be in pages, which by default is 16KB, but you can check:
SHOW GLOBAL STATUS LIKE 'Innodb_page_size';

hi

mine is like this

BUFFER POOL AND MEMORY
----------------------
Total memory allocated 10752867514; in additional pool allocated 25947648
Buffer pool size   589824
Free buffers       1
Database pages     567582
Modified db pages  5


so how much Buffer Pool Size ?? 500K ??

also
from console

mysql> SHOW GLOBAL STATUS LIKE 'Innodb_buffer_pool_pages_total';
+--------------------------------+--------+
| Variable_name                  | Value  |
+--------------------------------+--------+
| Innodb_buffer_pool_pages_total | 589824 |
+--------------------------------+--------+
1 row in set (0.17 sec)

mysql> SHOW GLOBAL STATUS LIKE 'Innodb_page_size';
+------------------+-------+
| Variable_name    | Value |
+------------------+-------+
| Innodb_page_size | 16384 |
+------------------+-------+
1 row in set (0.17 sec)


so how much ram is utilizing ..   ??

Innodb_buffer_pool_pages_total  * Innodb_page_size = 589824 * 16384 = 9663676416 Bytes
= 9 GB

hi thanks

is there any documentation of this calculation ?

total innodb_buffer_pol_size uses = Innodb_buffer_pool_pages_total  * Innodb_page_size

can you please give me the link
thanks

http://dev.mysql.com/doc/refman/5.0/en/server-status-variables.html#statvar_Innodb_buffer_pool_pages_total
Innodb_buffer_pool_pages_total : The total size of buffer pool, in pages

http://dev.mysql.com/doc/refman/5.0/en/server-status-variables.html#statvar_Innodb_page_size
Innodb_page_size : The compiled-in InnoDB page size (default 16KB)

I provided those earlier, but thanks for clarifying - I had to go offline for awhile.
