Chart Description
Cache Hit Rate

Shows a recent summary of the percentage of file requests that are satisfied by the file cache, and that do not require a disk read.

Cache Size

Shows the recent history of memory allocated to the file cache.

Memory allocated to the file cache is dynamic. This is controlled by the Disk Cache Manager, and will alter the level of memory based upon how much physical memory is being used by other applications and is available in the system.

Physical Cache I/O Shows the rate of Reads and Writes being made to the file cache.
Cache Faults

This chart displays the number of faults that occur when a requested page is not found in the file system cache, and must be retrieved from elsewhere.

The chart displays the number of faults, NOT the number of pages faulted in each operation.
