从日志记录中排除 EF 消息

Question

我正在 .Net C# Azure 函数应用程序中配置日志记录，以将日志消息发送到 Azure Application Insights。请参阅下面我的 Program.cs 内容。如何配置日志记录以不记录 EntityFramework 消息？

请注意，我要删除的规则应该阻止记录除错误之外的任何内容，并且我确实希望记录 LogInfo() 消息。

var config = new ConfigurationBuilder()
    .AddJsonFile("local.settings.json", optional: true, reloadOnChange: true)
    .AddEnvironmentVariables()
    .Build();
var connectionString = config["defaultConnection"];

var host = new HostBuilder()
    .ConfigureFunctionsWorkerDefaults(worker => worker.UseNewtonsoftJson())
    .ConfigureServices(services =>
    {
        services.AddApplicationInsightsTelemetryWorkerService();
        services.ConfigureFunctionsApplicationInsights();
    })
    .ConfigureLogging(logging =>
    {
        logging.Services.Configure<LoggerFilterOptions>(options =>
        {
            foreach (LoggerFilterRule rule in options.Rules)
            {
                if (rule.ProviderName == "Microsoft.Extensions.Logging.ApplicationInsights.ApplicationInsightsLoggerProvider")
                    defaultRule = rule;
            }
            if (defaultRule is not null)
            {
                options.Rules.Remove(defaultRule);
            }
        });
    })
    .ConfigureOpenApi()
    .ConfigureServices(services =>
    {
        services.AddDbContext<DijestContext>(options =>
                options.UseSqlServer(
                connectionString,
                sqlServerOptions => sqlServerOptions.CommandTimeout(600)));
    }
    )
    .Build();

host.Run();

我认为将其添加到您的

ConfigureLogging

的开头应该可以解决问题

logging.AddFilter("Microsoft.EntityFrameworkCore", LogLevel.None);
logging.AddFilter("Default", LogLevel.Information);
