keepalived + asp.net core2.1 + entityframework + 禁用console

    public partial class PaintingLineDbContext : DbContext
    {
        // 输出到Console
        public static readonly LoggerFactory LoggerFactory =
            new LoggerFactory(new[] { new ConsoleLoggerProvider((_, __) => true, true) });

        protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
        {
            base.OnConfiguring(optionsBuilder);

            var env = Environment.GetEnvironmentVariable("ASPNETCORE_ENVIRONMENT");
            if (env == "Development")
            {
                optionsBuilder.UseLoggerFactory(LoggerFactory);
            }
        }

    }

supervisor配置文件：api.ini

[program:api]
command=dotnet21 OpenAuth.PaintLine.WebApi.dll
directory=/app/api
environment=ASPNETCORE__ENVIRONMENT=Production
user=root
stopsignal=INT
autostart=true
autorestart=true
startsecs=1
stderr_logfile=/var/log/api.err.log
stdout_logfile=/var/log/api.out.log

.net core 2.1 + keepalived部署的时候，一直在往/var/log/api.out.log写文件，经过排查发现：

不知道哪位大哥加了这么一段代码 optionsBuilder.UseLoggerFactory(LoggerFactory); ，导致entityframework大量输出日志级别为debug和info的信息，进而导致supervisor一直疲于往文件写日志。然后我的服务器CPU就爆满了。
