Hooking into SignalR event in Blazor ServerSide - blazor-server-side

Question

I have found this piece of code for the default logging mechanism provided by Microsoft:
public static IHostBuilder CreateHostBuilder(string[] args) =>
Host.CreateDefaultBuilder(args)
.ConfigureLogging(logging =>
{
logging.ClearProviders();
logging.AddConsole();
logging.AddFilter(
"Microsoft.AspNetCore.SignalR", LogLevel.Trace);
logging.AddFilter(
"Microsoft.AspNetCore.Http.Connections",
LogLevel.Trace);
})
.ConfigureWebHostDefaults(webBuilder =>
{
webBuilder.UseStartup<Startup>();
});
My set for Serilog is as follows:
public class Program
{
public static void Main(string[] args)
{
try
{
using IHost host = CreateHostBuilder(args).Build();
host.Run();
}
catch (Exception ex)
{
if (Log.Logger == null || Log.Logger.GetType().Name == "SilentLogger")
{
Log.Logger = new LoggerConfiguration()
.MinimumLevel.Debug()
.WriteTo.Console()
.CreateLogger();
}
Log.Fatal(ex, "Host terminated unexpectedly");
}
finally
{
Log.CloseAndFlush();
}
}
private static IHostBuilder CreateHostBuilder(string[] args)
=> Host.CreateDefaultBuilder(args)
.UseServiceProviderFactory(new AutofacServiceProviderFactory(Register))
.ConfigureWebHostDefaults(webBuilder =>
{
webBuilder.UseStartup<Startup>()
.CaptureStartupErrors(true)
.ConfigureAppConfiguration(config => { config.AddJsonFile("appsettings.Local.json", optional: true); })
.UseSerilog((hostingContext, loggerConfiguration) =>
{
loggerConfiguration
.ReadFrom.Configuration(hostingContext.Configuration)
.Enrich.FromLogContext()
.Enrich.WithProperty("ApplicationName", typeof(Program).Assembly.GetName().Name)
.Enrich.WithProperty("Environment", hostingContext.HostingEnvironment);
#if DEBUG
loggerConfiguration.Enrich.WithProperty("DebuggerAttached", Debugger.IsAttached);
#endif
});
});
private static void Register(ContainerBuilder builder) => builder.RegisterLogger(autowireProperties: true);
}
How do I add SignalR filters to my setup?

In Serilog terminology you need to override the minimum level for the Microsoft SignalR namespaces.
public static IHostBuilder CreateHostBuilder(string[] args) => Host.CreateDefaultBuilder(args)
.UseSerilog((context, config) =>
{
/*
* the rest of the Serilog configuration here
*/
config.MinimumLevel.Override("Microsoft.AspNetCore.SignalR", LogEventLevel.Debug);
config.MinimumLevel.Override("Microsoft.AspNetCore.Http.Connections", LogEventLevel.Debug);
})
.ConfigureWebHostDefaults(webBuilder => { webBuilder.UseStartup<Startup>(); });
