Estou usando Powershell 5 e Filebeat para resolver esse problema.
Note que isso não foi testado mais do que algumas horas e é uma prova de conceito.

{
Write-Host $Match.Groups["Date"].Value
$FileDate = [datetime]::ParseExact($Match.Groups["Date"].Value, "yyyy-MM-dd", $null)
$TimeSince = New-TimeSpan -Start $FileDate -End (Get-Date).Date
if ($TimeSince.TotalDays -ge $NumberOfDaysToKeepFiles)
{
Remove-Item $FilePath
}
}
}
Isso criará um arquivo csv no diretório $ Path, se você alterar os contadores, ele criará um novo arquivo com (1-9) no nome.
