I have the following NLog config file below. It's set to Archive every day and initially I had just the MaxArchiveFiles. Now I would like to keep only X amount of days of archived files and found the info that says MaxArchiveDays is available in v4.7 and up. So, I upgraded to v4.7 but now it doesn't seem to archive either on Days or File number.
Anyone see anything wrong with this config file with NLog v4.7?

<logger name="defaultLogger" minlevel="Debug" writeTo="DefaultTarget,ConsoleTarget" />

** UPDATE **
<target name="DefaultTarget"
xsi:type="File"
fileName="${LogDirectory}/LogFile.log"
encoding="utf-8"
layout="${longdate} | ${callsite} | ${message}"
archiveFileName="${LogDirectory}/Archive/{#}_log.log"
archiveNumbering="DateAndSequence"
archiveAboveSize="3145728"
archiveEvery="Day"
maxArchiveFiles="3"
maxArchiveDays="2"
/>
The problem is the use of ${shortdate}
:
archiveFileName="${LogDirectory}/Archive/${shortdate}_log.{#}.log"
archiveNumbering="Rolling"
When using Layout in archiveFileName
then it must be very static. Only {#}
should contain the dynamic part.
Instead try this:
archiveFileName="${LogDirectory}/Archive/{#}_log.log"
archiveNumbering="DateAndSequence"
