{ CML$DISK_DEVICE_USAGE_DATA
{
{
{ PURPOSE:
{    The purpose of this statistic is to record the amount of work
{ performed by a particular disk storage device. This information is
{ used by maintenance personnel to measure the failure rate per
{ amount of service performed.
{
{ FREQUENCY: Every half-hour.
{
{ CONTENT:
{    The  descriptive-data portion of this statistic contains:
{
{    '<mf>.<unit>*<vsn>'
{
{      where <mf> is the identification of the mainframe in the form
{        $SYSTEM_mmmm_ssss.  Where 'mmmm' is the model number of
{        Central Processor zero (CP0), e.g. 0990, and 'ssss' is the
{        serial number of that processor, e.g. 0104.
{
{      where <unit> is the element name of the disk storage
{        device whose work is being recorded.
{
{      where <vsn> is the recorded-vsn of the disk volume which was
{        the object of the work performed.
{
{    The  counter-value portion of this statistic contains:
{
{    1.  Total number of MAUs read from this storage device since the
{        the system was last initialized.
{    2.  Total number of MAUs written to this storage device since
{        the system was last initialized.
{    3.  Total number of i/o requests issued for this storage device
{        since the system was last initialized.
