The status of the memory available versus in use.
The maximum amount of memory available for all image caching.
The memory currently in use for caching static and dynamic images.
The percentage of image requests (static and dynamic) satisfied by accessing the
cache.
• 100 * (# of cache hits) / (# of cache hits + # of cache misses)
• # of cache hits - the number of times an image was requested that the image was
found in the cache
• # of cache misses - the number of times an image was requested that the image
could not be found in the cache, and the image had to either be loaded from flash
or obtained via the network (for dynamic images). It is considered a RAM Cache
Miss even if the image is subsequently found in flash cache.
The maximum flash space allocated for image caching.
Flash space is used for caching only when there is not enough available memory in
the RAM cache for a newly requested image (it is used only for dynamic images).
The percentage of image requests (dynamic only) that are satisfied by
accessing the flash cache.
• 100 * (# of flash cache hits) / (# of flash cache hits + # of flash cache misses)
• # of flash cache hits - # of times a dynamic image could not be found in RAM
cache but was found in flash cache
• # of flash cache misses - # of times a dynamic image could not be found in either
RAM or flash cache. RAM cache hits are not relevant in this calculation.
The number of images that are currently stored in the Flash cache.
