// Description:
//    Additions to the V2.6 Metrics MOF to support a more generic
//    approach.
// 
//    CIM users often desire metric objects that model designers have
//    not
//    provided. Furthermore, such needs vary from one management
//    philosophy
//    to another. Rather than fill more and more CIM models with
//    standardized objects, the Metrics model supports externally
//    defined
//    expressions of existing objects, such as properties of
//    CIM_StatisticalData and its subclasses. In addition, the
//    classes described in this file enable users to define their own
//    metrics at runtime (rather than at provider implementation time).
//    A newly defined metric (aka CIM_BaseMetricDefinition) may be
//    given a value by instantiating CIM_BaseMetricValue.
//    Both CIM_BaseMetricDefinitions and CIM_BaseMetricValues may be
//    associated with a ManagedElement.
// ==================================================================
// CIM 2.8 (Preliminary) - None
// 
// CIM 2.7.0 (Preliminary) 5 June 2002
//     CR820 - Defined Base Metrics Classes and associations
//     CR851 - Change the Description of BaseMetricValue.Duration
//             to define the timestamp as the end of the duration
// CIM 2.7.0 (Final) 17 March 2003
//     CR987 - Remove experimental qualifier from:

   [Version ("2.7.0"), Description (
       "CIM_BaseMetricDefinition represents the definitional aspects "
       "of a metric, i.e., a definition template containing meta data "
       "about a new metric.  Since CIM_BaseMetricDefinition does not "
       "capture metric instance information, it does not contain the "
       "value of the metric.  The associated class CIM_BaseMetricValue "
       "holds the metric value and encapsulates its runtime behavior.  "
       "The purpose of CIM_BaseMetricDefinition is to provide a "
       "convenient mechanism for introducing a new metric definition "
       "at runtime and capturing its instance values in a separate "
       "class.  This mechanism is targeted specifically at CIM users "
       "who would like to enhance existing CIM schemas by introducing "
       "domain-specific metrics that are not captured in the existing "
       "CIM schemas.  In addition, vendors of managed resources may "
       "make use of this mechanism if a small subset of a potentially "
       "large and heterogeneous amount of performance-related data "
       "needs to be exposed, based on the context in which the data is "
       "captured.  Additional meta data for a metric can be provided "
       "by subclassing from CIM_BaseMetricDefinition.  The "
       "CIM_BaseMetricDefinition should be associated with the "
       "CIM_ManagedElement(s) to which it applies.") ]

          "1=\"Non-calculable\" -> a string.  Arithmetic makes no "

          "2=\"Summable\" -> It is reasonable to sum this value over "
          "many instances of e.g., UnitOfWork, such as the number of "
          "files processed in a backup job.  For example, if each "
          "backup job is a UnitOfWork, and each job backs up 27,000 "

       "instance exists after the metric information is captured is "
       "not defined and is implementation dependent.\n"
       "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 "
