Serilog.Enrichers.Thread

Enrich Serilog events with properties from the current thread.

Getting started

Install the package from NuGet:

Install-Package Serilog.Enrichers.Thread

In your logger configuration, apply Enrich.WithThreadId():

Log.Logger = new LoggerConfiguration()
    .Enrich.WithThreadId()
    .CreateLogger();

Many sinks simply include all properties without further action required, so the thread id will be logged automatically. However, some sinks, such as the File and Console sinks use an output template and the new ThreadId may not be automatically output in your sink. In this case, in order for the ThreadId to show up in the logging, you will need to create or modify your output template.

w.File(...., outputTemplate:
  "{Timestamp:yyyy-MM-dd HH:mm:ss.fff zzz} [{Level:u3}] {Message:lj} {Properties}{NewLine}{Exception}")

Here, {Properties} can include not only ThreadId, but any other enrichment which is applied. Alternatively, {ThreadId} could be used instead, if you want to only add the thread id enrichment.

An example, which also uses the Serilogs.Sinks.Async Nuget package, is below:

            var logger = Log.Logger = new LoggerConfiguration()
                 .MinimumLevel.Debug()
                 .WriteTo.Console(restrictedToMinimumLevel:Serilog.Events.LogEventLevel.Information)
                 .WriteTo.Async(w=>w.File("..\\..\\..\\..\\logs\\SerilogLogFile.json", rollingInterval: RollingInterval.Day, outputTemplate: "{Timestamp:yyyy-MM-dd HH:mm:ss.fff zzz} [{Level:u3}] {Message:lj} <{ThreadId}>{NewLine}{Exception}"))
                 .Enrich.WithThreadId()
                 .CreateLogger();

Which would produce an output in the log file as follows:

2018-04-06 13:12:45.684 +02:00 [ERR] The file file_name.svg does not exist <4>

Where, <4> is an example thread id.

To use the enricher, first install the NuGet package:

Install-Package Serilog.Enrichers.Thread

rychlym/serilog-enrichers-thread

Serilog.Enrichers.Thread
