DCIM_BaseMetricValue
Table 69. BaseMetricValue
Property Description
Duration
Property that represents the time duration over which this metric value is valid. This
property should not exist for timestamps that apply only to a point in time but should be
defined for values that are considered valid for a certain time period (ex. sampling). If the
Duration property exists and is non null, the TimeStamp is to be considered the end of the
interval.
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 that is creating or defining the InstanceID or that is a registered ID assigned
to the business entity by a recognized global authority. (This requirement 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 reused to identify different underlying (real-world)
elements. If the above preferred algorithm is not used, the defining entity must assure that
the resulting InstanceID is not reused across any InstanceIDs produced by this or other
providers for the NameSpace of this instance. For DMTF-defined instances, the preferred
algorithm must be used with the <OrgID> set to CIM.
MetricDefinitionId
The key of the BaseMetricDefinition instance for this CIM_BaseMetricValue instance value.
MetricValue
The value of the metric represented as a string. Its original data type is specified in
CIM_BaseMetricDefinition.
TimeStamp
Identifies the time when the value of a metric instance is computed. Note that this is
different from the time when the instance is created. For a given CIM_BaseMetricValue
instance, the TimeStamp changes whenever a new measurement snapshot is taken if
Volatile is true. A managmenet application may establish a time series of metric data by
retrieving the instances of CIM_BaseMetricValue and sorting them according to their
TimeStamp.
Volatile
If true, Volatile indicates that the value for the next point in time may use the same object
and just change its properties (such as the value or timestamp). If false, the existing objects
remain unchanged and a new object is created for the new point in time.
DCIM_LogEntry
Table 70. LogEntry
Property Description
CreationTimeStamp
A LogEntry may include a timestamp for the entry.
ElementName
A user-friendly name for the object. This property allows each instance to define a user-
friendly name in addition to its key properties, identity data, and description information.
NOTE: The Name property of ManagedSystemElement is also defined as a
user-friendly name. But, it is often subclassed to be a Key. It is not reasonable
that the same property can convey both identity and a user-friendly name,
without inconsistencies. Where Name exists and is not a Key (such as for
