Small util library to work with app insights library

Utils

ServiceNameInitializer

Adjust all telemetry with role name. Helps to search in metrics

To register it just add the following code when you are building your service provider

services.AddSingleton<ITelemetryInitializer>(new ServiceNameInitializer(<RoleName>));

AvoidSamplingTelemetryInitializer

Prevents metrics, which match the specified condition, to be sample on the client-side To register it just add the following code when you are building your service provider

services.AddSingleton<ITelemetryInitializer>(
    new AvoidSamplingTelemetryInitializer(
        t => t is RequestTelemetry telemetry && telemetry.Name == operationName))

AvoidRequestSamplingTelemetryInitializer

Just a small convenient wrapper around AvoidSamplingTelemetryInitializer

services.AddSingleton<ITelemetryInitializer>(
    new AvoidRequestSamplingTelemetryInitializer(operationName))

TelemetryClientExtensions.ExecuteAsRequest/TelemetryClientExtensions.ExecuteAsRequestAsync

Executes operations as RequestTelemetry Usage

await telemetryClient.ExecuteAsRequestAsync(new ExecuteAsRequestAsyncOptions(operationName, func));

Optional fields

• Action<IOperationHolder<RequestTelemetry>>? Configure - if more telemetry details need to be added. Is called right before operations itself
• int? FlushWait - time for telemetry to be pushed. Usefull for console apps. In secondss - default 15
• Action? PostExecute - is called after an operation just before operation.Dispose(). That means logs will still be attached to the RequestTelemetry and method execution time will be included

HttpResponseTelemetryInitializer

Enrich telemetry with response content to dependency http requests.

services.AddSingleton<ITelemetryInitializer>(
    new HttpResponseTelemetryInitializer(
        c => c.StatusCode >= HttpStatusCode.BadRequest))
