Correct way to use Serilog with WebApi2

I am in search of the correct way to use serilog with aspnet webapi2. As for now I initialize the global Log.Logger property like that :

   public static void Register(HttpConfiguration config)

        Log.Logger = new LoggerConfiguration()
            .WriteTo.Elasticsearch(new ElasticsearchSinkOptions(new Uri("http://localhost:9200"))
                IndexFormat = IndexFormat,
                BufferBaseFilename = outputLogPath,
                AutoRegisterTemplate = true,
                AutoRegisterTemplateVersion = AutoRegisterTemplateVersion.ESv6,
                CustomFormatter = new ElasticsearchJsonFormatter(renderMessageTemplate: false),
                BufferFileCountLimit = NbDaysRetention
            .MinimumLevel.ControlledBy(new LoggingLevelSwitch() { MinimumLevel = LogEventLevel.Information})

        //Trace all requests
        SerilogWebClassic.Configure(cfg => cfg.LogAtLevel(LogEventLevel.Information));


            name: "DefaultApi",
            routeTemplate: "api/{controller}/{id}",
            defaults: new { id = RouteParameter.Optional }

Is there a more cleaner way to do it? I am wondering, if this might be a problem if I have to put some test in place for my controllers.
