请看一下这篇文章

如果是.NET core web项目，则可以使用以下代码在Program.cs中设置日志级别：

public static IWebHostBuilder CreateWebHostBuilder(string[] args) =>
    WebHost.CreateDefaultBuilder(args)
    .UseStartup<Startup>()
    .ConfigureLogging(
        builder =>
        {

            builder.AddApplicationInsights("app insights instrumentation key");

            // You can set log level here
            builder.AddFilter<Microsoft.Extensions.Logging.ApplicationInsights.ApplicationInsightsLoggerProvider>
                             ("", LogLevel.Information);
        }
    );
