And to program the desired custom property, anywhere in your request pipeline have something like. Filtering with telemetry processors lets you filter out telemetry in the SDK before it's sent to the server. You can use filtering with sampling, or separately. The screenshot below provides an example of a Log analytics query on a custom property: We now ask the question of how do you go about logging custom telemetry to Application Insights from within your ASP.NET Core application? Adding an initializer by using ApplicationInsights.config or TelemetryConfiguration.Active isn't valid for ASP.NET Core applications or if you're using the Microsoft.ApplicationInsights.WorkerService SDK. For Windows systems, the SDK automatically creates a temporary local folder in the %TEMP% or %LOCALAPPDATA% directory and restricts access to administrators and the current user only.
