Using Serilog

Setup

Install the package Akka.Logger.Serilog to utilize Serilog

PM> Install-Package Akka.Logger.Serilog

This will also install the required Serilog packages.

Next, you'll need to configure the global Log.Logger and also specify to use the logger in the config when creating the system, for example like this:

var logger = new LoggerConfiguration()
    .WriteTo.ColoredConsole()
    .MinimumLevel.Information()
    .CreateLogger();
Serilog.Log.Logger = logger;
var system = ActorSystem.Create("my-test-system", "akka { loglevel=INFO,  loggers=[\"Akka.Logger.Serilog.SerilogLogger, Akka.Logger.Serilog\"]}");

Logging

To log inside an actor, using the normal string.Format() syntax, get the logger and log:

var log = Context.GetLogger();
...
log.Info("The value is {0}", counter);

To log using Serilog syntax you need to use the SerilogLogMessageFormatter:

var log = Context.GetLogger(new SerilogLogMessageFormatter());
...
log.Info("The value is {Counter}", counter);
