Hello,
I don't understand what's wrong.
The DotNetNuke.log4net.config says:
maximumFileSize value="10MB"
maxSizeRollBackups value="5"

However, in /Portals/_default/Logs there are more than 1000 files, with a total of 131MB.

How to properly configure DotNetNuke.log4net.config to limit how many file should be kept?

Thanks!

Unfortunately, Log4Net doesn't support trimming the logs when using date "rolling," i.e. when it is setup to create a new file for each day, the maxSizeRollBackups setting is ignored (see the final Caution section of http://logging.apache.org/log4net/rel...). To keep the logging to 5 10MB files, change rollingStyle to Size instead of Date.

To answer some of the previous questions in this thread, the Log4Net log is more in-depth/diagnostic logging than what the Site Log or Event Log provides. It is capable of logging lots of information in addition to what gets logged by the Event Viewer. So long as you aren't investigating an issue, you should be free to delete all of the log files.

Thanks, Brian.
rollingStyle 'date' is a lot more useful. I'll keep it, and look for a PowerShell script to purge files older XX days. Someone should have already done that... if not I'll create it.

$Path = "C:\www\" # or a list of paths like "D:\www\mysite1\","D:\www\mysite2\"
$Daysback = "-120"
$CurrentDate = Get-Date
$DatetoDelete = $CurrentDate.AddDays($Daysback)

Get-ChildItem -Path $Path -Filter *.log.resources -Recurse | Where-Object { $_.LastWriteTime -lt $DatetoDelete -and $_.Directory -like "*\_default\Logs"} | Remove-Item
