Measures reported by HitachiCacheTest

This test reports how well the objects in the cache have been utilized.

 The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
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. %
