Release Note:Changed bytes_read, bytes_written to type long to prevent metrics overflow.
bytes_read, and bytes_written metrics are using int (MetricsTimeVaryingInt) as counter. This type is too small to store the bytes_read and bytes_written metrics. Recommend to change this to long (metricsLongValue).
