CIM_MediaAccessStatData Superclass: CIM_StatisticalData
Statistics related to reading and writing at a specific MediaAccessDevice, or for a specific StorageExtent. The same class is used to represent this data - whether for the MediaAccessDevice (independent of the StorageExtent), OR for the Extent (independent of its AccessDevice). The element whose statistics are described is associated using the relationship, ElementStatisticalData. Note that this class models the same properties as MediaAccessStatInfo. This class, however, uses the simplified key mechanisms of its superclass, StatisticalData.

Parameters (local in grey)
Counter
uint64 ReadOperations ;
The number of attempted read operations.
Counter

The number of unrecoverable write operations.
Counter
uint64 RecoveredWriteOperations ;
The number of recovered write operations.

Required
Override ( "ElementName" )
string ElementName ;
The user friendly name for this instance of StatisticalData. In addition, the user friendly name can be used as a index property for a search of query. (Note: Name does not have to be unique within a namespace.)
datetime SampleInterval = "00000000000000.000000:000" ;
Some statistics are sampled at consistent time intervals. This property provides the sample interval so that client applications can determine the minimum time that new statistics should be pulled. If the statistics are not sampled at consistent time intervals, this property must be set to a zero time interval.
datetime StartStatisticTime ;
The time, relative to managed element where the statistic was collected, when the first measurement was taken. If the statistic is reset, the StartStatisticTime is the time when the reset was performed.
datetime StatisticTime ;
The time the most recent measurement was taken, relative to the managed element where the statistic was collected.
Key
string InstanceID ;
Within the scope of the instantiating Namespace, InstanceID opaquely and uniquely identifies an instance of this class. In order to ensure uniqueness within the NameSpace, the value of InstanceID SHOULD be constructed using the following 'preferred' algorithm:
<OrgID>:<LocalID>
Where <OrgID> and <LocalID> are separated by a colon ':', and where <OrgID> MUST include a copyrighted, trademarked or otherwise unique name that is owned by the business entity creating/defining the InstanceID, or is a registered ID that is assigned to the business entity by a recognized global authority (This is similar to the <Schema Name>_<Class Name> structure of Schema class names.) In addition, to ensure uniqueness <OrgID> MUST NOT contain a colon (':'). When using this algorithm, the first colon to appear in InstanceID MUST appear between <OrgID> and <LocalID>.
<LocalID> is chosen by the business entity and SHOULD not be re-used to identify different underlying (real-world) elements. If the above 'preferred' algorithm is not used, the defining entity MUST assure that the resultant InstanceID is not re-used across any InstanceIDs produced by this or other providers for this instance's NameSpace.
For DMTF defined instances, the 'preferred' algorithm MUST be used with the <OrgID> set to 'CIM'.
uint32ResetSelectedStats(
Array of strings indicating which statistics to reset.
Qualifiers:IN
string SelectedStatistics [ ]
)
Method to reset one or more of the instance's statistics. The method takes one parameter as input - an array of strings indicating which statistics to reset. If all the statistics in the instance should be reset, the first element of the array MUST be set to 'All' or 'ALL'. If one or more individual statistics should be reset, the corresponding property names are entered into the elements of the array.
The method returns 0 if successful, 1 if not supported, and any other value if an error occurred. A method is specified so that the StatisticalInformation's provider/ instrumentation, which calculates the statistics, can reset its internal processing, counters, etc.
In a subclass, the set of possible return codes could be specified, using a ValueMap qualifier on the method. The strings to which the ValueMap contents are 'translated' may also be specified in the subclass as a Values array qualifier.
MaxLen ( 64 )
string Caption ;
The Caption property is a short textual description (one- line string) of the object.
string Description ;
The Description property provides a textual description of the object.
