|
| 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 that is 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. 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. |
