MetricSampleType Enumeration

In This Topic

Determines what the raw data for a given sampled metric is, and how it has to be processed to produce final values.

Syntax

Visual Basic
C#

'Declaration
 
Public Enum MetricSampleType 
   Inherits System.Enum

public enum MetricSampleType : System.Enum

Members

Member	Value	Description
IncrementalCount	2	Each sample is the incremental change since the prior sample as of the timestamp of the sample.
IncrementalFraction	3	Each sample has the numerator and denominator expressed as the incremental change since the prior sample as of the timestamp of the sample.
RawCount	0	Each sample value is in final form for display as of the timestamp of the sample.
RawFraction	1	Each sample value has the numerator and denominator of a fraction for display as of the timestamp of the sample.
TotalCount	4	Each sample value is the cumulative total up to the timestamp of the sample
TotalFraction	5	Each sample value has the numerator and denominator expressed as the total up to the timestamp of the sample.

Remarks

In many cases it is necessary to store raw facts that are translated into the final display value during the display process so that they work regardless of time resolution. For example, to determine the percentage of processor time used for an activity, you need to know a time interval to look across (say per second, per hour, etc.), how many units of work were possible during that interval (time slices of the processor) and how many were used by the process. By specifying the TotalFraction type, the metric display system will automatically inspect the raw and baseline values then translate them into a percentage. This enumeration is conceptually similar to the Performance Counter Type enumeration provided by the runtime, but has been simplified for easier use.
