| Write_Pending_Rate |
Indicates the percentage of writes to this cache that are currently pending.
|
% |
A high value could be a cause for concern, as it could indicate a bottleneck while writing to the cache.
|
| CleanQueue_UsageRate |
Indicates the percentage of the this cache's clean queue currently utilized.
|
% |
Since all pending read/write requests to a cache typically reside in a queue, excessive queue usage (i.e., a high value for this measure) is often an indication that too many requests are yet to be processed by the cache and hence, are still in queue. This could be a result of a processing bottleneck on the cache or a cache overload. You might have to investigate further to diagnose the root-cause of this anomaly.
On the other hand, if the values of these measures are low, it is a sign of good cache health.

| MiddleQueue_UsageRate |
Indicates the percentage of this cache's middle queue currently utilized.
|

| PhysicalQueue_UsageRate |
Indicates the percentage of the cache's physical queue currently utilized.

| TotalQueue_UsageRate |
Indicates the percentage of the cache queue currently utilized.
