Cache pools are the logical repositories of cache data. This cached data is the information from web page or application stored in the device to make the browsing faster. The cached data saves the loading time since it occupies the space in the device.

Close monitoring of the cache pool is essential to determine the adequacy of the buffer allocation to the cache. The cache buffer allocation failures can be tracked and reported through this test.

Outputs of the test : One set of results for each Cache pool in the target Cisco ASR Router.

Measurement	Description	Measurement Unit	Interpretation
size	Indicates the total number of cache buffers in this cache pool.	Number	.
used	Indicates the number of cache buffers that were used from this cache pool.	Number
allocteHit	Indicates the number of cache buffers allocated from this cache pool.	Number	A very low value could indicate that many cache buffer allocations have failed owing to the lack of adequate cache buffers.
dAllocateMiss	Indicates the number of cache buffer allocations from this cache pool that failed due to unavailability of cache buffers.	Number	Ideally, the cache buffer miss count should be 0.
dFree	Indicates the number of unused/free cache buffers in this cache pool.	Number
dPercent	Indicates the percentage of cache buffer used currently in this cache pool.	Percent	If the cache buffer size is less, then for many requests the cache buffer cannot be used leading to more swapping; therefore the cache buffer size needs to be increased.
