Accumulator for calculated metrics.

Represents a single configured metric that needs to be calculated and reported on top of the telemetry items that pass through the pipeline. Includes a set of filters that define which telemetry items to consider, a projection which defines which field to use as a value, and an aggregation which dictates the algorithm of arriving at a single reportable value within a second.

OR-connected collection of AND-connected filter groups.

Represents the collection configuration - a set of calculated metrics, performance counters, and full telemetry documents to be collected by the SDK.

This class is a hub for all pieces of configurable collection configuration. Upon initialization - it creates collection-time instances of and maintains them in separate collections by telemetry type. These are used to filter and calculated calculated metrics configured by the service. - it creates collection-time instances of which are used to filter and send out full telemetry documents. - it creates certain metadata collections which are used by other collection-time components to learn more about what is being collected at any given time.

Gets a list of performance counters.

Performance counter name is stored in CalculatedMetricInfo.Projection.

Represents the part of the QuickPulse accumulator which holds calculated metric data. As telemetry item pass through the pipeline, they are being filtered, projected, and the resulting values are stored here - both for calculated metrics and full telemetry document streams. Unlike the main accumulator, this one might not have finished being processed at swap time, so the consumer should keep the reference to it post-swap and make the best effort not to send prematurely. indicates that the accumulator is still being processed when non-zero.

Used by writers to indicate that a processing operation is still in progress.

Gets a dictionary of metricId => AccumulatedValues.

Represents a concept of a uniquely identifiable set of full telemetry documents that are being reported by the SDK. The notion of a stream is needed since multiple UX sessions might be querying for full telemetry documents with different filtering criteria simultaneously.
