NLog不会扩展文件大小

Question

I have the following defined for testing to see if the specified log files roll over but I never see it happening. Any ideas?

<target name="file" xsi:type="File" layout="${message}" 
        filename="${specialfolder:folder=CommonApplicationData}/logs/configlog.log" 
        archiveFileName="configlog.{##}.log" archiveAboveSize="5" archiveNumbering="Rolling" concurrentWrites="True" maxArchiveFiles="50" 
        keepFileOpen="True" encoding="iso-8859-2" enableFileDelete="False"></target>

Answer 1

You should also include the path in your archiveFileName, so something like this will work:

<target name="file" xsi:type="File" layout="${message}" 
    filename="${specialfolder:folder=CommonApplicationData}/logs/configlog.log"
    archiveFileName="${specialfolder:folder=CommonApplicationData}/logs/archive/configlog.{##}.log" archiveAboveSize="5" archiveNumbering="Rolling" concurrentWrites="True" maxArchiveFiles="50" 
    keepFileOpen="True" encoding="iso-8859-2" enableFileDelete="False"></target>

Also: The archiveAboveSize parameter is in bytes, not megabytes. At the moment you telling nlog to roll over after 5 bytes, which might be causing issues.
