Description:
The InnoDB Buffer Usage graph is definitely reporting almost exactly one third of the actual usage normally measured on the server (compared to previous versions of Workbench and my other current monitors, of course).

I have many instances whose usage is constantly over 99%, but in Workbench they're all showing as only e.g.,  33.2%.

How to repeat:

Thank you for the bug report.

Fixed as of the upcoming MySQL Workbench 6.3.8 release, and here's the
changelog entry:

The usage graph under InnoDB Status in the Performance Dashboard
consistently underreported the actual usage of the InnoDB buffer pool as
reported on the server. This fix implements a new formula to represent the
InnoDB buffer pool.

Thank you for the bug report.
