We currently plot the InnoDB BP read/write requests so we can see activity within BP, but we are missing how many InnoDB reads from disk occur, and what ratio of misses exist. Consider adding two new Query elements to graph InnoDB Buffer Pool Requests:
- Read requests from disk
- Buffer Pool cache misses
If you implement #2, then also set "use 2nd Y-Axis" via an override and set Right Y Axis Unit = percent 0-100. Also you might need to use the or irate() notation to smooth over any missed data points.
