View API usage per user per hour

As a company grows, you undoubtedly have more api only users being created.  As these users start to access the API reading/writing/updating Marketo - this will have an impact on performance.  As an Admin, currently we can only view a daily total of API calls made by each api user.  What would be a great improvement would be to provide a report into an up to the minute view on how the API is being used.

This would allow Admins to view which API users are potentially doing low-value updates during a very impacted time of day - thus affecting scheduled/triggered campaigns.

It would also give more insight as to what vendors/add-ons' integrations may be affecting normal Marketo performance.  Anything that makes the ship sail faster!
