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. If your hit rate is low, you may want to consider
enabling Flash 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.
