Hit Rates chart

The Hit Rates chart shows the Hit Rates for the main SQL Server caches.

A Hit Rate indicates the amount of work (I/O or compilations) that is being saved by caching information in memory.

Hit rates are shown for the following caches:

Buffer Cache
Procedure Cache - The hit rate for this cache will vary widely depending on how the application is written. This figure is averaged for all procedure cache object types except ad hoc SQL.

Spotlight calculates its hit rates using a differential sampling method. Unlike most Amazon RDS for SQL Server monitors, it is not reporting the average hit rate since Amazon RDS for SQL Server started.
