Recommended MySQL statistics for production environment
I'd highly recommend using MONyog.



  MONyog MySQL Monitor and Advisor is a "MySQL DBA in a box'' that helps
  MySQL DBAs manage more MySQL servers, tune their current MySQL servers
  and find and fix problems with their MySQL database applications
  before they can become serious problems or costly outages.


Our DevOps team uses this extensively for both production and development. These guys have most of the "best practices" baked into the application, so we really don't need to get our hands too dirty in the DBA stuff.
