Enrich Serilog log events with properties from open telemetry spans using .NET’s Activity API.

❗ Important

This repository is now deprecated. Serilog now has the native ability to log span related data. See #332.

What Does It Do?

Enriches logs with a spans unique identifier, parent unique identifier and ASP.NET’s trace unique identifier. Serilog.Enrichers.Span is an add-on to Serilog to log exception details and custom properties that are not output in Exception.ToString().

Getting Started

Add the Serilog.Enrichers.Span NuGet package.

dotnet add package Serilog.Enrichers.Span

When setting up your logger, add the WithSpan() line like so:

using Serilog;
using Serilog.Enrichers.Span;

ILogger logger = new LoggerConfiguration()
    .Enrich.WithSpan()
    .WriteTo.RollingFile(
        new JsonFormatter(renderMessage: true), 
        @"C:\logs\log-{Date}.txt")    
    .CreateLogger();
