How do I automatically tail (delete) older logs using Serilog in a .Net WPF application?

I'm using Serliog in a .Net WPF application.

Is there a way that I can "tail" (delete) the log files automatically when they are over N days old?

According to the documentation, the retention period for logs is determined by the retainedFileCountLimit setting. By default, retainedFileCountLimit has a value of 31 so only the most recent 31 log files are kept.

When configuring Serilog programmatically, you can adjust the number of files retained by specifying the retainedFileCountLimit parameter as follows:

var log = new LoggerConfiguration()
    .WriteTo.File("log.txt", retainedFileCountLimit: 42)
    .CreateLogger();

pass null to remove the limit.

When configuring Serilog using XML (in the <appSettings>):

<appSettings>
  <add key="serilog:using:File" value="Serilog.Sinks.File" />
  <add key="serilog:write-to:File.path" value="log.txt" />
  <add key="serilog:write-to:File.retainedFileCountLimit" value="42"/>
</appSettings>

and pass an empty string to remove the limit.

When configuring Serilog using JSON (in an appsettings.json file):

{
  "Serilog": {
    "WriteTo": [
      {
        "Name": "File",
        "Args": {
          "path": "log.txt",
          "retainedFileCountLimit": "42"
        }
      }
    ]
  }
}

and pass an empty string to remove the limit.

Now you can also specify a property retainedFileTimeLimit: https://github.com/serilog/serilog-sinks-file/pull/90

By the way, don't forget to specify retainedFileCountLimit: null if you want limitation only by the date. With the current implementation default value of retainedFileCountLimit is 31. Therefore, if you leave the parameter out, this filter will also be applied

https://github.com/serilog/serilog-sinks-rollingfile/blob/dev/README.md Look there. You can configure autocreation of a new log file every day and also you can set how many of them you want to be kept
