Class AdaptiveTelemetrySampler

java.lang.Object

com.microsoft.applicationinsights.internal.channel.sampling.AdaptiveTelemetrySampler

All Implemented Interfaces:

TelemetrySampler, Stoppable

public final class AdaptiveTelemetrySampler
extends java.lang.Object
implements Stoppable, TelemetrySampler

This sampler will keep the outgoing telemetries within the limit that was decided by the user. This sampler will change the sampling rate as needed to keep up in the pace, as opposed to the 'FixedRateTelemetrySampler' This sampler employs the FixedRateTelemetrySampler for doing the actual sampling and a timer for re-evaluating the sampling percentage.
