In Measure output, each subfield provides four values, one for each size of DP2 cache block:
Cache Block SizeField Label
512 bytesC0
1024 bytesC1
2048 bytesC2
4096 bytesC3
CW
(Legacy Style only) Cache write metrics. This field is divided into these subfields:
Counter TypeDescriptionSubfield
AccumulatingNumber of times a required block is found dirty in cache
for a write operation.
WRITE-DIRTYS
AccumulatingNumber of times a required block is found clean in cache
for a write operation, which saves a disk read per write.
WRITE-CLEANS
AccumulatingNumber of times a required block is not found in cache
for a write operation, which requires a disk read before
the write can be performed.
WRITE-MISSES
IncrementingNumber of block splits (per block size) for the volume.BLOCK-SPLITS

In H-series and J-series RVUs, this counter has a value of 1.
Counter type: Max queue.
INPUT-BYTES-F
(Legacy Style only) In G-series RVUs, same as INPUT-BYTES but accommodates larger values (64
