iops uint32 Input/output operations per second, calculated over the interval since these statistics were last requested or reset. This value will be zero if it has not been requested or reset since a controller restart.
number-of-reads uint64 For the controller whose host ports had I/O activity, the number of read operations since these statistics were last reset or since the controller was restarted.
read-cache-hits uint64 For the controller that owns the volume, the number of times the block to be read is found in cache.
read-cache-misses uint64 For the controller that owns the volume, the number of times the block to be read is not found in cache.
