Akka.Logger.Serilog

This is the Serilog integration plugin for Akka.NET. Please check out our documentation on how to get the most out of this plugin.

Targets Serilog 2.12.0.

Semantic Logging Syntax

If you intend on using any of the Serilog semantic logging formats in your logging strings, you need to use the SerilogLoggingAdapter inside your instrumented code or there could be elsewhere inside parts of your ActorSystem:

var log = Context.GetLogger<SerilogLoggingAdapter>(); // correct
log.Info("My boss makes me use {semantic} logging", "semantic"); // serilog semantic logging format

or

var log = MyActorSystem.GetLogger<SerilogLoggingAdapter>(myContextObject); // correct
log.Info("My boss makes me use {semantic} logging", "semantic"); // serilog semantic logging format

or

var log = MyActorSystem.GetLogger<SerilogLoggingAdapter>(contextName, contextType); // correct
log.Info("My boss makes me use {semantic} logging", "semantic"); // serilog semantic logging format

This will allow all logging events to be consumed anywhere inside the ActorSystem, including places like the Akka.NET TestKit, without throwing FormatExceptions when they encounter semantic logging syntax outside of the SerilogLogger.

Adding Property Enricher To Your Logs

Default Properties

You can add property enrichers to the logging adapter that will be added to all logging calls to that logging adapter.

var log = Context.GetLogger<SerilogLoggingAdapter>()
    .ForContext("Address", "No. 4 Privet Drive")
    .ForContext("Town", "Little Whinging")
    .ForContext("County", "Surrey")
    .ForContext("Country", "England");
log.Info("My boss makes me use {Semantic} logging", "semantic");

All logging done using the log ILoggingAdapter instance will append "Address", "Town", "County", and "Country" properties into the Serilog log.

One-off Properties

You can add one-off property to a single log message by appending PropertyEnricher instances at the end of your logging calls.

var log = Context.GetLogger<SerilogLoggingAdapter>();
log.Info(
    "My boss makes me use {Semantic} logging", "semantic",
    new PropertyEnricher("County", "Surrey"), 
    new PropertyEnricher("Country", "England"));

This log entry will have "County" and "Country" properties added to it.

Automatically Convert ILoggingAdapter into SerilogLoggingAdapter

As of Akka.Logger.Serilog v1.5.25, you can now do the following:

var log = Context.GetLogger()
    .ForContext("Address", "No. 4 Privet Drive")
    .ForContext("Town", "Little Whinging")
    .ForContext("County", "Surrey")
    .ForContext("Country", "England");
log.Info("My boss makes me use {Semantic} logging", "semantic");

And it will work without having to explicitly call Context.GetLogger<SerilogLoggingAdapter>() first.
