Telemetry Enrichment

Serilog Correlation Enrichment

The Arcus.WebApi.Telemetry.Serilog library provides a Serilog enricher that adds the correlation information of the current request to the log event as a log property called TransactionId and OperationId.


  • TransactionId: A5E90591-ADB0-4A56-818A-AC5C02FBFF5F
  • OperationId: 79BB196A-B0CC-4F5C-B48A-AB87850346AF


The enricher requires access to the application services so it can get the correlation information. Following example shows how the Serilog logger is configured in the Startup.cs file.

using Arcus.Observability.Correlation;
using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Hosting;
using Serilog;

public class Startup
public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
Log.Logger = new LoggerConfiguration()
.Enrich.With(new CorrelationInfoEnricher(app.ApplicationServices))
