Extracts auto-collected, pre-aggregated (aka. "standard") metrics from telemetry. Metric Extractors participate in the telemetry pipeline as telemetry processors. They examine telemetry items going through the pipeline and create pre-aggregated metrics based on the encountered items. The metrics can be anything. For example, one may choose to extract a metric for "Request Duration" from RequestTelemetry items. Or one may choose to create a metric "Cows Sold" from specific user-tracked EventTelemetry items that contain respective information.
Metric Extractors should be placed into the pipeline after telemetry initializers and before any telemetry processors that may perform any kind of filtering, e.g. before any sampling processors. Placing metric extractors after any filters will prevent them from seeing all potentially relevant telemetry which will skew the extracted metrics.
This extractor is responsible for aggregating auto-collected, pre-aggregated (aka. "standard") metrics, such as failed request count, dependency call durations and similar. Users may use the same pattern to create their own extractors for any metrics they want from any kind of telemetry. This extractor contains several implementations of the (internal) ISpecificAutocollectedMetricsExtractor-interface to which it delegates the aggregation of particular metrics. All those implementations share the same -instance for metric aggregation.

We have dedicated instance variables to refer to each individual extractors because we are exposing some of their properties to the config subsystem here. However, for calling common methods for all of them, we also group them together.

Gets the metric manager that owns all extracted metric data series. The MetricManager allows participating extractors to access the Microsoft.ApplicationInsights.Extensibility.MetricManager instance that aggregates all metrics to be extracted. Participants should call on this instance for construction of all data series to be extracted from telemetry. This will ensure that all metric documents are aggregated and tagged correctly and are processed using the instance used to initialize this extractor.

An instance of this class is contained within the telemetry processor. It extracts auto-collected, pre-aggregated (aka. "standard") metrics from DependencyTelemetry objects which represent invocations of the monitored service.

Auto-Discovering Dependency Types: ** Dependency call duration is collected as a metric for failed and successful calls separately, and grouped by dependency type. It is essential to control the number of data series produced by this extractor: It must be a small, bounded value. However, this extractor needs to support different modules that collect information about different kinds of dependencies. To meet these constraints, the extractor will auto-discover dependency types, but it will not auto-discover more types than the number controlled by the property. The first MaxDependencyTypesToDiscover dependency types encountered will be tracked separately. Additional types will all be grouped as "Other". Customers should set this value to a value such that "Other" does not actually occur in practice. As a guidance, a good value will be approximately in range 1 - 20. If significantly more types are expected, it should be examined whether the dependency type field is used appropriately. If MaxDependencyTypesToDiscover is set to 0, dependency calls will not be grouped by type.
