Elastic Common Schema Serilog Text Formatter

This ITextFormatter implementation formats a Serilog event into a JSON representation that adheres to the Elastic Common Schema specification.


The .NET assemblies are published to NuGet under the package name Elastic.CommonSchema.Serilog

How to Enable

var logger = new LoggerConfiguration()
                .WriteTo.Console(new EcsTextFormatter())

In the code snippet above new EcsTextFormatter() enables the text formatter and instructs Serilog to format the event as JSON. The sample above uses the Console sink, but you are free to use any sink of your choice, perhaps consider using a filesystem sink and Elastic Filebeat for durable and reliable ingestion.

In ASP.NET (core) applications

.UseSerilog((ctx, config) =>
  // Ensure HttpContextAccessor is accessible
  var httpAccessor = ctx.Configuration.Get<HttpContextAccessor>();

    .WriteTo.Async(a => a.Console(new EcsTextFormatter()));

The WithEcsHttpContext ensures logs will be enriched with HttpContext data.

An example of the output is given below:

Option Description
MapCurrentThead true map ecs.process by looking up the Process from the current thread
MapHttpAdapter null a way to map HttpContextAccessor to ECS fields.
LogEventsPropertiesToFilter A Set<string> of properties that should not be emitted as labels.* or metadata.*
MapCustom A Func that allows you to mutate the EcsDocument before its fully converted.

ECS Aware Message Templates

This formatter also allows you to set ECS fields directly from the message template using properties that adhere to the https://messagetemplates.org/ format.

The available ECS message template properties are listed under LogTemplateProperties.* e.g LogTemplateProperties.TraceId

Log.Information("The time is {TraceId}", "my-trace-id");

Will override trace.id on the resulting ECS json document.
