How to enable Debug logs for troubleshoot problems. #8622

When you encounter problems in the development or production environment, we would like to see the log to troubleshoot the problem.

.MinimumLevel.Debug() will set MinimumLevel to Debug to show more logs.

We don't want to see EF Core's Debug logs when your problem has nothing to do with EF Core.

var loggerConfiguration = new LoggerConfiguration()
    .MinimumLevel.Debug()
    .MinimumLevel.Override("Microsoft.EntityFrameworkCore", LogEventLevel.Warning)
    .Enrich.FromLogContext()
    .WriteTo.Async(c => c.File("Logs/logs.txt"))

If you have an EF Core-related problem, you can remove MinimumLevel.Override("Microsoft.EntityFrameworkCore", LogEventLevel.Warning) and EnableSensitiveDataLogging to see EF Core debug logs.

Configure<AbpDbContextOptions>(options =>
{
    /* The main point to change your DBMS.
     * See also BookStoreMigrationsDbContextFactory for EF Core tooling. */
    options.UseSqlServer();
    
    options.Configure(configureOptions =>
    {
        configureOptions.DbContextOptions.EnableSensitiveDataLogging();
    });
});

If your API website experiences a JWT authentication problem, please ShowPII and output identity model logs.

 public async static Task<int> Main(string[] args)
{
    IdentityModelEventSource.ShowPII = true;

    IdentityModelEventSource.Logger.LogLevel = EventLevel.Verbose;
    var wilsonTextLogger = new TextWriterEventListener("Logs/identitymodel.txt");
    wilsonTextLogger.EnableEvents(IdentityModelEventSource.Logger, EventLevel.Verbose);

If you have an OpenIddict related problem, please override the OpenIddict log level to Verbose.

var loggerConfiguration = new LoggerConfiguration()
    .MinimumLevel.Debug()
    .MinimumLevel.Override("Microsoft.EntityFrameworkCore", LogEventLevel.Warning)
    .MinimumLevel.Override("OpenIddict", LogEventLevel.Verbose)
    .Enrich.FromLogContext()
    .WriteTo.Async(c => c.File("Logs/logs.txt"))
