In `pt-variable-advisor`:

> WARN innodb\_log\_file\_size: The InnoDB log file size is set to its default value, which is not usable on production systems.

`innodb_log_file_size` is deprecated, and this is what we should use now:

`innodb_redo_log_capacity = ...`

However, the warning still appears, because I’m not setting `innodb_log_file_size`.

I believe this should be updated.

And it can probably suggest that the formula should be (25% of buffer pool size) \* innodb\_log\_files\_in\_group (default/recommended = 2)

(if you agree, of course)

Thanks!!
