This package targets NetStandard2.0, and hence can be used in .NET Core 2.1 or higher, and .NET Framework 4.7.2 or higher. Although Metrics Explorer gives you the option to filter out synthetic sources, this option reduces traffic and ingestion size by filtering them at the SDK itself. You can write your own telemetry processors. Transmission instances are stored on local disk also when there are network problems. Filtering with telemetry processors lets you filter out telemetry in the SDK before it's sent to the server. Send cloud role name to appinsight using serilog - Microsoft Q&A For the full list of configuration settings, see the Configurable settings in channels section later in this article. If builder.Services.AddApplicationInsightsTelemetry(aiOptions) for ASP.NET Core 6.0 or services.AddApplicationInsightsTelemetry(aiOptions) for ASP.NET Core 3.1 and earlier is used, it overrides the settings from Microsoft.Extensions.Configuration.IConfiguration.
