Description:
For every Open_xxx status information we do have an Opened_xxx status information:
SQL> show global status like 'open%';
+--------------------------+-------+
| Variable_name            | Value |
+--------------------------+-------+
| Open_files               | 2     |
| Open_streams             | 0     |
| Open_table_definitions   | 47    |
| Open_tables              | 102   |

| Opened_files             | 23    |
| Opened_table_definitions | 68    |
| Opened_tables            | 126   |
+--------------------------+-------+
Except for Open_streams. Add Opened_streams status information if this feature is still supported. Otherwise remove it.

How to repeat:
SQL> show global status like 'open%';
+--------------------------+-------+
| Variable_name            | Value |
+--------------------------+-------+
| Open_files               | 2     |
| Open_streams             | 0     |
| Open_table_definitions   | 47    |
| Open_tables              | 102   |

| Opened_files             | 23    |
| Opened_table_definitions | 68    |
| Opened_tables            | 126   |
+--------------------------+-------+

Suggested fix:
Opened_streams status counter should be added.
