Integer stat (statistic) entry. This entry contains stat value, together with domain value. The purpose is that both absolute values and percentages can be determined. The entry contains (optional) timestamp to determine freshness of the data and/or sort and plot them.

Item Summary
Name	Type	Multiplicity	Description
value	property int	[0,1]	Primary (absolute) value of that stat.
domain	property int	[0,1]	Size of the domain.
percentage	property float	[0,1]	Percentage value.
timestamp	property dateTime	[0,1]	Sampling timestamp.

Items
- value
  
  Flags: RAM,runtime
  
  Multiplicity: [0,1]
  
  Primary (absolute) value of that stat. This is the value that we are interested in. E.g. this is the number of objects in collection.
  
  Even though this is a primary value, it is optional. There may be rare cases when we do not have primary value, we only have percentage data.
- domain
  
  Flags: RAM,runtime
  
  Multiplicity: [0,1]
  
  Size of the domain. This is the value of "all things" used to compute percentage. E.g. this is the number of object in collection domain.
- percentage
  
  Flags: RAM,runtime
  
  Multiplicity: [0,1]
  
  Percentage value. This is usually not present, as it may be easily computed from value and domain. But for rare cases there may be just the percentage and the primary value may be missing.
  
  Implementation note: Having percentage here also makes it easier for implementation. The code can use the same data structure to store intermediate values, e.g. stat with computed percentage. The collection-processing code can also fill in the percentage value automatically, even if it is not stored in repository. This is somehow simimar to the way provisioning code fills in the attributes into the shadow.
- timestamp
  
  Flags: RAM,runtime
  
  Multiplicity: [0,1]
  
  Sampling timestamp. The timestamp of the moment when the value was retrieved or computed.
