c# - Serilog - 多个日志文件

Question

我正在使用 Serilog 进行日志记录，但无法弄清楚如何将日志事件分离到不同的文件中。例如，我想将错误记录到 error_log-ddmmyyyy.txt，将警告记录到 warn_log-ddmmyyyy.txt。

这是我的记录器配置:

Log.Logger = new LoggerConfiguration()
            .WriteTo.Logger(lc =>
                lc.Filter.ByIncludingOnly(Matching.WithProperty("Level", "Warning"))
                    .WriteTo.RollingFile(
                        Path.Combine(AppDomain.CurrentDomain.BaseDirectory, @"Logs\warn_log-{Date}.txt"),
                        outputTemplate: OutputTemplate))
            .WriteTo.Logger(lc =>
                lc.Filter.ByIncludingOnly(Matching.WithProperty("Level", "Error"))
                    .WriteTo.RollingFile(
                        Path.Combine(AppDomain.CurrentDomain.BaseDirectory, @"Logs\error_log-{Date}.txt"),
                        outputTemplate: OutputTemplate))
            .CreateLogger();

它仅在我在日志消息中明确指定 {Level} 属性时才有效。

我正在尝试使用:

Matching.WithProperty<LogEventLevel>("Level", l => l == LogEventLevel.Warning)

但还是不行。

我使用以下配置，它对我有用:

            Log.Logger = new LoggerConfiguration()
                    .MinimumLevel.Debug()
                    .WriteTo.LiterateConsole()
                    .WriteTo.Logger(l => l.Filter.ByIncludingOnly(e => e.Level == LogEventLevel.Information).WriteTo.RollingFile(@"Logs\Info-{Date}.log"))
                    .WriteTo.Logger(l => l.Filter.ByIncludingOnly(e => e.Level == LogEventLevel.Debug      ).WriteTo.RollingFile(@"Logs\Debug-{Date}.log"))
                    .WriteTo.Logger(l => l.Filter.ByIncludingOnly(e => e.Level == LogEventLevel.Warning    ).WriteTo.RollingFile(@"Logs\Warning-{Date}.log"))
                    .WriteTo.Logger(l => l.Filter.ByIncludingOnly(e => e.Level == LogEventLevel.Error      ).WriteTo.RollingFile(@"Logs\Error-{Date}.log"))
                    .WriteTo.Logger(l => l.Filter.ByIncludingOnly(e => e.Level == LogEventLevel.Fatal      ).WriteTo.RollingFile(@"Logs\Fatal-{Date}.log"))
                    .WriteTo.RollingFile(@"Logs\Verbose-{Date}.log")
                    .CreateLogger();
