Windows servers can generate tons of log files on a daily basis. Managing those log files can be a chore. Ignoring the log files is not an option, as too many log files could fill up a hard drive.
We recently automated the process of logfile clean up by using a Powershell script that deletes files older than 90 days. The script was then placed in task scheduler to run nightly.
The script was is a modified version of one found on the internet. The original source was pretty simple; we stripped it down even further. There are only 2 variables to set. Each of the variables is set in the code instead of passing them along via the command line.
The first variable is $days. Set this to how many files you want to keep. Ours is -90 for 90 days.
The second is $Path. Set this to the path of the files to delete. Ours was “C:\inetpub\logs\LogFiles\W3SVC2” This will vary based upon applications and websites used.
Here is the code:
Foreach ($File in Get-ChildItem -Path $FilePath)
if ($File.LastWriteTime -lt ($(Get-Date).Adddays($days)))
remove-item -path $File -force
Write-Host “Removed logfile: ” $File
Write-Host “Removing IIS-logs keeping last” $days “days”
