You can modify a few common settings by passing ApplicationInsightsServiceOptions to AddApplicationInsightsTelemetry, as in this example: This table has the full list of ApplicationInsightsServiceOptions settings: For the most current list, see the configurable settings in ApplicationInsightsServiceOptions. To learn how to configure the list of counters to be collected, see EventCounters introduction. You can create a storage directory yourself and configure the channel to use it. Get an instance of TelemetryClient by using constructor injection and call the required TrackXXX() method on it. The items are serialized, compressed, and stored into a Transmission instance once every 30 seconds, or when 500 items have been buffered. These modules are responsible for automatically collecting telemetry. This article is designed to avoid this issue entirely, by not using user secrets.

Modify the ConfigureServices method of the Startup.cs class as shown here: Configuring the channel by using TelemetryConfiguration.Active isn't supported for ASP.NET Core applications. If you need to do a synchronous flush, use InMemoryChannel. It depends on factors like how many items or Transmission instances are in memory, how many are on disk, how many are being transmitted to the back end, and whether the channel is in the middle of exponential back-off scenarios. It doesn't prevent any automatic collection modules from collecting telemetry. The parameter provides the target that the algorithm tries to achieve.
