TracingContextDecorator

TracingContextDecorator is a component that enriches logs with opentelemetry tracing context e.g. traceid, spanid, parentspanid into log messsage. Implementation of required abstractions for specific libraries lives inside src subdirectory. All examples are inside examples subdirectory.

Supported log libraries

There are four supported libraries. Each of them uses different abstractions to achieve the goal.

  • Log4net
  • Microsoft.Extensions.Logging
  • NLog
  • Serilog

Log4net requires PatternLayoutConverter implementation and its configuration in the context of specific appender.

Microsoft.Extensions.Logging requires specific implementation of formatter. This package contains implementation of console formatter.

NLog requires implementation of LayoutRenderer.

Serilog requires implementation of ILogEventEnricher interface.

Above components can be configured via code or config file. Examples for Log4net and NLog show how to do that via configuration.

Usage

Using TracingContextDecorator requires addition of dependencies. Dependendencies can be added via

dotnet add package or dotnet add reference. You can learn what's needed looking into examples or

reading documentation for specific log library. Below dependencies excerpt from serilog example:

  <ItemGroup>
    <PackageReference Include="Serilog.Sinks.Console" Version="5.0.1" />
  </ItemGroup>^M
  <ItemGroup>
    <ProjectReference Include="..\..\src\TracingContextDecorator.csproj" />
  </ItemGroup>^M
