Managing IIS Log Files Location and Retention Policies
Jul 17, 2025 am 12:39 AM
IIS logs are stored in the inetpub\logs\LogFiles directory of the C drive by default and will not be cleaned automatically. The retention period needs to be controlled manually or through scripts. To modify the path, you can open IIS Manager → select a site or server node → double-click "Login" → click "..." to select a new directory. It is recommended to use non-system disks such as D:\IISLogs or multiple servers to configure the network path in a unified manner; setting retention time can be achieved through Log Parser scripts, task planning PowerShell scripts (such as 30 days of retention), third-party tools, etc.; in addition, it is recommended to adjust the log format as needed, close unnecessary fields, or temporarily close the debug log, and enable log compression to optimize performance and space usage.
The location and retention strategy of IIS log files are actually not that complicated, but if you don’t pay attention to the settings, it is easy to fill the disk or not find key information over time. Let me directly talk about the key points: By default, the IIS logs are inetpub\logs\LogFiles directory of the system disk, and are not automatically cleaned by default. The retention period needs to be controlled manually or through scripts.
Modify IIS log storage path
Many people didn't pay attention at the beginning, and the default log was written on disk C, but after a few months, they found that the system disk was almost full. Modifying the path is actually very simple:
- Open IIS Manager → Select a site or server node → Double-click "Logs"
- Click the “…” button next to “Select File Directory” to select a new path
- It is recommended to place it on a non-system disk, such as D:\IISLogs or a special log partition
After the operation is completed, the new log will be written to the new location. If there are multiple servers, they can be configured as a network path (but you need to pay attention to permissions and stability).
Set log retention time
IIS itself does not have the function of deletion by day, so you have to find a way to do this part yourself. There are several common practices:
Clean up regularly using Log Parser scripts
Microsoft's Log Parser tool can filter logs by date and execute deletion regularly in conjunction with batch processing or PowerShell scripts.-
Task plan deletion script
Write a simple PowerShell script, such as keeping only the logs for the last 30 days:$Path = "D:\IISLogs" $Daysback = "-30" $CurrentDate = Get-Date $DelDate = $CurrentDate.AddDays($Daysback) Get-ChildItem $Path -Recurse | Where-Object { $_.LastWriteTime -lt $DelDate } | Remove-Item -Force -RecurseThen use the Windows Task Planner to run once a day in the early morning.
Third-party tool-assisted management
For example, using LogRotate for Windows or some centralized log management solutions (ELK, Splunk, etc.), is suitable for enterprise environments.
The log format and whether it is enabled are also worth noting
Many people ignore the impact of log content itself on performance and capacity:
- The default is W3C format, and the recorded information is already relatively complete, but if certain fields are not needed (such as User-Agent, Cookies, etc.), you can uncheck in the "Log" setting to reduce volume
- If you are just debugging, you can temporarily close log writing to avoid meaningless growth
- It is a good habit to enable log compression. Although IIS will do it by default, remember to confirm whether "Allow log file rolling updates" is enabled.
Basically that's it. Modifying the path and setting up retention strategies are the two most critical steps. The rest depends on how your monitoring and analysis needs are arranged. Not complicated, but it is easy to ignore details.

Using Slf4j for log management in Java API development
Jun 18, 2023 pm 12:25 PM
In Java development, log management is a very important task. Normally, programmers use the System.out.println statement to output log information, but this method is not suitable in many cases. Because it not only affects the performance of the program, but is also prone to problems when thread locking is encountered. Slf4j is a commonly used Java log management framework. It does not rely on a specific underlying log implementation, but uses a more general log interface. The advantages of Slf4j are that it can be used in different
