Class CIM_BaseMetricValue
extends CIM_ManagedElement

Each CIM_BaseMetricValue object represents the instance value of a metric. Since the gathering of metric information can involve large quantities of information there may be many instances of this class. The use of this class as an instrumentation source may be inefficient unless the rate of metrics are known. The length of time a CIM_BaseMetricValue instance exists after the metric information is captured is not defined and is implementation dependent. Most metric data values change over time. There are two ways of mapping this into CIM_BaseMetricValue objects: The value for the next point in time may use the same object and just change its properties (such as the value or timestamp), or the existing objects remain unchanged and a new object is created for the new point in time. The first method is typically used for snapshot data and the second method for historical data. Which method is used, is indicated by the Volatile property.

BreakdownDimensionstring
DescriptionstringIf present, specifies one BreakdownDimension from the BreakdownDimensions array defined in the associated CIM_ BaseMetricDefinition. This is the dimension along which this set of metric values is broken down. For a description of the concept, see the class CIM_BaseMetricDefinition.None TRANSLATABLE= true
BreakdownValuestring
DescriptionstringDefines a value of the BreakdownDimension property defined for this metric value instance. For instance, if the BreakdownDimension is "TransactionName", this property could name the actual transaction to which this particular metric value applies.None TRANSLATABLE= true
Captionstring
DescriptionstringThe Caption property is a short textual description (one- line string) of the object.None TRANSLATABLE= true
MaxLenuint3264None None
Descriptionstring
DescriptionstringThe Description property provides a textual description of the object.None TRANSLATABLE= true
Durationdatetime
DescriptionstringProperty 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 nonNull, the TimeStamp is to be considered the end of the interval.None TRANSLATABLE= true
ElementNamestring
DescriptionstringA 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 that ManagedSystemElement's Name property 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 instances of LogicalDevice), the same information MAY be present in both the Name and ElementName properties.None TRANSLATABLE= true
InstanceIdstring
DescriptionstringA unique identifier of this instance of the metric value. This must be a globally unique identifier.None TRANSLATABLE= true
KeybooleantrueNone OVERRIDABLE= false
MeasuredElementNamestring
DescriptionstringA descriptive name for the element to which the metric value belongs (i.e., the measured element). This property is required by behavior if there is no association defined to a ManagedElement, but may be used in other cases to provide supplemental information. This allows metrics to be captured independently of any ManagedElement. An example is where a metric value belongs to a combination of elements, such as the input and output ports of the traffic in a switch. If there are multiple ManagedElements associated with the metric value, then usually there is one that naturally belongs to the metric value and that one should be used to create the supplemental information. The property is not meant to be used as a foreign key to search on the measured element. Instead, the association to the ManagedElement should be used.None TRANSLATABLE= true
MetricDefinitionIdstring
DescriptionstringThe key of the BaseMetricDefinition instance for this CIM_BaseMetricValue instance value.None TRANSLATABLE= true
ModelCorrespondencestringCIM_BaseMetricDefinition.IdNone None
RequiredbooleantrueNone OVERRIDABLE= false
MetricValuestring
DescriptionstringThe value of the metric represented as a string. Its original data type is specified in CIM_BaseMetricDefinition.None TRANSLATABLE= true
RequiredbooleantrueNone OVERRIDABLE= false
TimeStampdatetime
DescriptionstringIdentifies 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.None TRANSLATABLE= true
Volatileboolean
DescriptionstringIf 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.None TRANSLATABLE= true
