serilog 只记录调试、错误和警告日志，而不记录信息 [英] serilog to log only debug, error and warning logs but not information

问题描述

我有一个配置了用于日志记录的 serilog 的应用程序.我的应用程序中有一个复选框，只有单击该复选框按钮时，它才会记录所有信息日志，否则只记录错误和警告日志.

I have an application with serilog configured for logging. I have a checkbox in my application, only on clicking that checkbox button it should log all information log else only Error and Warning log should be logged.

在调试模式下，如何在取消选中按钮时仅记录调试、错误和警告日志.从 2 天以来我一直在尝试这样做.我已经使用 .MinimumLevel.Debug()/restrictedToMinimumLevel: LogEventLevel.Debug 尝试了 google/stackoverflow 中建议的所有方法，但它对我不起作用.它也记录信息日志.

In debug mode how to log only Debug, error and warning log when the button is unchecked. I have been trying to do this since 2 days. I have tried all the ways suggested in google/stackoverflow using .MinimumLevel.Debug()/restrictedToMinimumLevel: LogEventLevel.Debug it did not work for me. It logs Information log as well.

请帮我解决这个问题.仅记录调试、错误和警告日志.

Please help me on this. To log only Debug,error and warning log.

val 在复选框启用时为真:

val is true when checkbox enabled:

if (val == "true")
{
    _logger = new LoggerConfiguration()
                    .MinimumLevel.Debug()
                    .WriteTo.File(_filepath, restrictedToMinimumLevel: LogEventLevel.Information)
                    .CreateLogger();
}
else if (val == "false")
{
    _logger = new LoggerConfiguration()
                    .MinimumLevel.Debug()
                    .WriteTo.File(_filepath, restrictedToMinimumLevel: LogEventLevel.Debug)
                    .CreateLogger();
}

当 val 为 false 时，即未启用复选框时，应仅记录调试、错误和警告日志.

when val is false, it.e., when check box is not enabled, it should log only debug,error and warning logs.

推荐答案

您无法使用 MinimumLevel 作为 @barbsan 注释来实现它.

You cannot achieve it using MinimumLevelas @barbsan comment.

但是您可以使用过滤来处理您的情况.

But you can use filtering for in your case.

过滤器只是对 LogEvent

_logger  = new LoggerConfiguration()
    .MinimumLevel.Debug()
    .WriteTo.File(_filepath)
    .Filter.ByIncludingOnly(isNotInfoLevel)
    .CreateLogger();

在下面的函数中，您可以根据需要添加更多条件

And in below function you can add more conditions if needed

private static bool isNotInfoLevel(LogEvent le)
{
    return le.Level != LogEventLevel.Information;
}

使用ByExclusion排除信息层的另一种方法

Anther way by using ByExcluding to exclude information level

.Filter.ByExcluding((le) => le.Level == LogEventLevel.Information)
