我正在使用Serilog进行伐木而且不能使用Serilog弄清楚如何将日志事件分离到不同的文件。例如,我想将错误记录到error_log-ddmmyyyy.txt,并将警告记录到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();
仅当我在日志消息中指定{Level}属性时才有效。
我试图使用:
Matching.WithProperty<LogEventLevel>("Level", l => l == LogEventLevel.Warning)
但它也没有用。

我使用以下配置,它适用于我:
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();

我认为你需要:
.ByIncludingOnly(evt => evt.Level == LogEventLevel.Warning)
修改强>
在许多情况下,现在使用Serilog.Sinks.Map更简洁。有了它,这个例子可以写成:
Log.Logger = new LoggerConfiuration()
.WriteTo.Map(
evt => evt.Level,
(level, wt) => wt.RollingFile("Logs\\" + level + "-{Date}.log"))
.CreateLogger();

var dateTimeNowString = $"{DateTime.Now:yyyy-MM-dd_HH-mm-ss}";
Log.Logger = new LoggerConfiguration()
.MinimumLevel.Debug()
.MinimumLevel.Override("Microsoft", LogEventLevel.Warning)
.WriteTo.Logger(
x => x.Filter.ByIncludingOnly(e => e.Level == LogEventLevel.Error)
.WriteTo.File($"Logs/{dateTimeNowString}-Error.log")
)
.WriteTo.Logger(
x => x.Filter.ByIncludingOnly(e => e.Level == LogEventLevel.Warning)
.WriteTo.File($"Logs/{dateTimeNowString}-Warning.log")
)
.WriteTo.File($"Logs/{dateTimeNowString}-All.log")
.WriteTo.Console()
.CreateLogger();
这些是我的nuget包:
<PackageReference Include="Serilog.AspNetCore" Version="2.1.1" />
<PackageReference Include="Serilog.Sinks.Console" Version="3.1.1" />
<PackageReference Include="Serilog.Sinks.File" Version="4.0.0" />

另一种变体是在一个文件中具有ERROR和FATAL(而不是一个文件中的错误而另一个文件中的致命)。对于我来说似乎有很多文件要分开。只是要记住可以使用“或”运算符。
Log.Logger = new LoggerConfiguration()
.WriteTo.File("logs\\all.log", rollingInterval: RollingInterval.Day)
.WriteTo.Logger(
x => x.Filter.ByIncludingOnly(y => y.Level == Serilog.Events.LogEventLevel.Error || y.Level == Serilog.Events.LogEventLevel.Fatal)
.WriteTo.File("logs\\error.log", rollingInterval: RollingInterval.Day))
.CreateLogger();

通常,对于我的用例,我需要多个日志,每个日志都包含一个最低级别。这样,以后我可以更有效地调查日志。
对于最新版本的Serilog,我建议使用此版本:
Log.Logger = new LoggerConfiuration()
.MinimumLevel.Debug()
.WriteTo.File(path: "debug.log", rollingInterval: RollingInterval.Day)
.WriteTo.File(path: "info.log", restrictedToMinimumLevel: LogEventLevel.Information, rollingInterval: RollingInterval.Day)
.WriteTo.File(path: "error.log",restrictedToMinimumLevel: LogEventLevel.Error, rollingInterval: RollingInterval.Day)
.WriteTo.Console(restrictedToMinimumLevel: LogEventLevel.Warning)
.CreateLogger();
