IIS 7日志文件自动删除？

Question

Is there any feature in IIS 7 that automatically deletes the logs files older than a specified amt of days?

I am aware that this can be accomplished by writing a script(and run it weekly) or a windows service, but i was wondering if there is any inbuilt feature or something that does that.

Also, Currently we turned logging off as it is stacking up a large amount of space. Will that be a problem?

Answer 1

You can create a task that runs daily using Administrative Tools > Task Scheduler.

Set your task to run the following command:

forfiles /p "C:\inetpub\logs\LogFiles" /s /m *.* /c "cmd /c Del @path" /d -7

This command is for IIS7, and it deletes all the log files that are one week or older.

You can adjust the number of days by changing the /d arg value.

Answer 2

One line batch script:

forfiles /p C:\inetpub\logs /s /m *.log /d -14 /c "cmd /c del /q @file"

Modify the /d switch to change number of days a log file hangs around before deletion. The /s switch recurses subdirectories too.

Answer 3

Similar solution but in powershell.

I've set a task to run powershell with the following line as an Argument..

dir D:\IISLogs |where { ((get-date)-$_.LastWriteTime).days -gt 15 }| remove-item -force

It removes all files in the D:\\IISLOgs folder older than 15 days.

Answer 4

Another viable Powershell one-liner:

Get-ChildItem -Path c:\inetpub\logs\logfiles\w3svc*\*.log | where {$_.LastWriteTime -lt (get-date).AddDays(-180)} | Remove-Item -force

In case $_.LastWriteTime doesn't work, you can use $PSItem.LastWriteTime instead.
