Class PerformanceClientAbstract

Creates an instance of PerformanceClient, an abstract class containing core performance telemetry logic.

Saves extra information to be emitted when the measurements are flushed

Registers a callback function to receive performance events.

Adds queue measurement time to QueueMeasurements array for given correlation ID.

Calculates the difference between current time and time when function was queued. Note: It is possible to have 0 as the queue time if the current time and the queued time was the same.

Removes measurements for a given correlation id.

Emits events to all registered callbacks.

Stops measuring the performance for an operation. Should only be called directly by PerformanceClient classes, as consumers should instead use the function returned by startMeasurement. Adds a new field named as "[event name]DurationMs" for sub-measurements, completes and emits an event otherwise.

Generates and returns a unique id, typically a guid.

Abstract

Gets map of pre-queue times by correlation Id

Increment counters to be emitted when the measurements are flushed

Removes a callback registered with addPerformanceCallback.

Sets pre-queue time by correlation Id

Abstract

Starts measuring performance for a given operation. Returns a function that should be used to end the measurement.

Starts and returns an platform-specific implementation of IPerformanceMeasurement. Note: this function can be changed to abstract at the next major version bump.
