Der Exchange speichert eine Menge Logs – unter anderem für den IIS (Webserver den der Exchange nutzt), die Datenbanken und auch den Exchange selber.
Während man die Logs der Datenbanken entweder mit eigenen Mitteln klein halten kann (Stichwort Umlaufprotokollierung) oder über die Datensicherung (Stichwort Truncate Transactionlogs), müssen die anderen selbst bereinigt werden, damit die Platten nicht überlaufen.
Dies kann man auch mit einem Powershellscript automatisieren.
Erstellt dazu das folgende Powershellscript:
# Cleanup logs older than the set of days in numbers
$Days = 14
# Path of the logs that you like to cleanup
$IISLogPath = "C:\inetpub\logs\LogFiles\"
$ExchangeLoggingPath = "C:\Program Files\Microsoft\Exchange Server\V15\Logging\"
$ETLLoggingPath = "C:\Program Files\Microsoft\Exchange Server\V15\Bin\Search\Ceres\Diagnostics\ETLTraces\"
$ETLLoggingPath2 = "C:\Program Files\Microsoft\Exchange Server\V15\Bin\Search\Ceres\Diagnostics\Logs\"
$UnifiedContentPath = "C:\Program Files\Microsoft\Exchange Server\V15\TransportRoles\data\Temp\UnifiedContent"

Function Confirm-Administrator {
$currentPrincipal = New-Object Security.Principal.WindowsPrincipal( [Security.Principal.WindowsIdentity]::GetCurrent() )
if ($currentPrincipal.IsInRole( [Security.Principal.WindowsBuiltInRole]::Administrator )) {
return $true
} else {
return $false
}
}
if (-not (Confirm-Administrator)) {
Write-Output $msgNewLine
Write-Warning "This script needs to be executed in elevated mode. Start the Exchange Management Shell as an Administrator and try again."
$Error.Clear()
Start-Sleep -Seconds 2
exit
}
# Get size of all logfiles
Function Get-LogfileSize ($TargetFolder) {
if (Test-Path $TargetFolder) {
$Now = Get-Date
$LastWrite = $Now.AddDays(-$days)
$Files = Get-ChildItem $TargetFolder -Recurse | Where-Object { $_.Name -like "*.log" -or $_.Name -like "*.blg" -or $_.Name -like "*.etl" } | Where-Object { $_.lastWriteTime -le "$lastwrite" }
$SizeGB = ($Files | Measure-Object -Sum Length).Sum / 1GB
$SizeGBRounded = [math]::Round($SizeGB,2)
return $SizeGBRounded

}Dieses Powershellscript könnt ihr nun von Hand laufen lassen mit der Exchange Managementshell.
Wollt ihr das automatisieren mit den Task Schedular – solltet ihr das wie folgt anpassen:
# Cleanup logs older than the set of days in numbers
$Days = 14
# Path of the logs that you like to cleanup
$IISLogPath = "C:\inetpub\logs\LogFiles\"
$ExchangeLoggingPath = "C:\Program Files\Microsoft\Exchange Server\V15\Logging\"
$ETLLoggingPath = "C:\Program Files\Microsoft\Exchange Server\V15\Bin\Search\Ceres\Diagnostics\ETLTraces\"
$ETLLoggingPath2 = "C:\Program Files\Microsoft\Exchange Server\V15\Bin\Search\Ceres\Diagnostics\Logs\"
$UnifiedContentPath = "C:\Program Files\Microsoft\Exchange Server\V15\TransportRoles\data\Temp\UnifiedContent"

write-host "$TotalDeletedFiles files deleted"Natürlich solltet ihr noch die Tage und Pfade anpassen. Die Fehlermeldung bezüglich des UnifiedContent-Pfades ist in Ordnung, da der Exchange 2019 keine Unified Dienste mehr hat.
Um nun das ganze im Taskschedular starten zu können, müsst ihr noch einen Task bauen mit den folgenden Komponenten (diese natürlich ggf. anpassen):
- Programm: C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe
- Argument: -command C:\Tools\script.PS1
- Starten in: Ordner, in dem das Script liegt
