Azure WebJobs - How to disable adaptive sampling for application insights?-CodePudding

I came across

Is it possible to disable adaptive sampling?

Any help is much appreciated. Thank you!

CodePudding user response：

Simplest way is to set the SamplingSettings property to null:

.ConfigureLogging((loggingContext, builder) =>
{
    builder.AddConsole();
    builder.AddApplicationInsightsWebJobs(o =>
    {
        o.SamplingSettings = null;
    });
})

This prevents the AdaptiveSamplingTelemetryProcessor being added to the list of telemetry processors.

You can inspect whether adaptive sampling is active or not by taking a look at the TelemetryClient.TelemetryConfiguration.TelemetryProcessors property to see whether it contains an entry of type AdaptiveSamplingTelemetryProcessor or not.

You can disable Adaptive Sampling by going into the ApplicationInsights.config file, and remove or comment the AdaptiveSamplingTelemetryProcessor node.

<TelemetryProcessors>

<!-- Disable adaptive sampling:
  <Add Type="Microsoft.ApplicationInsights.WindowsServer.TelemetryChannel.AdaptiveSamplingTelemetryProcessor, Microsoft.AI.ServerTelemetryChannel">
    <MaxTelemetryItemsPerSecond>5</MaxTelemetryItemsPerSecond>
  </Add>
