serilog - 有没有办法通过appSetting配置来配置多个Serilog RollingFiles

Question

有没有办法通过appSetting配置多个Serilog RollingFiles？

我想为信息和错误级别创建单独的日志文件。

Answer 1

在应用程序设置中配置多个日志非常简单，任务是使用过滤器。我花了近 3 个小时试图弄清楚如何实现这一目标。

我最终做了以下事情:

Startup.cs/Global.asax.cs

Log.Logger = new LoggerConfiguration()
           .WriteTo
           .Logger(x => x.Filter
           .ByIncludingOnly(logEvent => logEvent.Level == Serilog.Events.LogEventLevel.Error)
           .ReadFrom
           .AppSettings("error"))

           .WriteTo
           .Logger(x => x.Filter
           .ByIncludingOnly(logEvent => logEvent.Level == Serilog.Events.LogEventLevel.Information)
           .ReadFrom
           .AppSettings("info")).CreateLogger()

Web.Config

<add key ="error:serilog:using:RollingFile" value="Serilog.Sinks.RollingFile"/>
<add key ="error:serilog:write-to:RollingFile.pathFormat" value="C:\log\error {Date}.txt"/>
<add key ="error:serilog:write-to:RollingFile.formatter" value="Serilog.Formatting.Json.JsonFormatter"/>

<add key ="info:serilog:using:RollingFile" value="Serilog.Sinks.RollingFile"/>
<add key ="info:serilog:write-to:RollingFile.pathFormat" value="C:\log\info {Date}.txt"/>
<add key ="info:serilog:write-to:RollingFile.formatter" value="Serilog.Formatting.Json.JsonFormatter"/>
