This test monitors the memory allocation within Cisco ASR Router. The usage of the buffer memory and its size are tracked and reported through this test. This test also helps the administrators to monitor the failure of buffer creation.

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

Measurement	Description	Measurement Unit	Interpretation
size	Indicates the current size of this buffer pool.	MB	A well-tuned environment is the one where this buffer should be sufficiently sized. A low value of this measure is always unhealthy.
totBuff	Indicates the number of buffers in this buffer pool.	Number	It includes both the allocated and free buffers.
freeBuff	Indicates the number of unused buffer in this buffer pool.	Number
allocateHit	Indicates the number of buffers allocated to this buffer pool.	Number	A very low value could indicate that many allocations have failed owing to lack of adequate buffers. If the measure repeatedly reports low values, it could be indicative of memory bottleneck in the router.
allocateMiss	Indicates the number of times buffer could not be allocated from this buffer pool.	Number	Ideally the buffer miss count should be 0. Repeated buffer misses indicate memory bottleneck in the router.
creationFail	Indicates the number of times the new buffers could not be created in this buffer pool.	Number	A low value is desired for this measure.
buffUsed	Indicates the number of used buffer space in this buffer pool.	Number
usedBuffPercent	Indicates the percentage of buffer used currently in this buffer pool.	Percent	If the buffer size is less, then for many requests the buffer cannot be used leading to more swapping; therefore the buffer size needs to be increased.
