Image Cache Status:
The status of the memory available versus in use.
RAM Max Size
The maximum amount of memory available for all image caching.
RAM Current Size
The memory currently in use for caching static and dynamic images.
RAM Hit Rate
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.
Items in Cache
(RAM)
The number of images that are currently stored in the RAM cache.
Flash Current Size
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).
Flash Hit Rate
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.
Items in Cache
(Flash)
The number of images that are currently stored in the Flash cache.
