Iis logs where to find

Logs can potentially fill up an entire hard drive. To mitigate this problem, many users turn off logging completely. Fortunately, there are alternatives to doing so, such as the following:.

The above mitigations are described in the sections below. You may also want to do the following to control disk usage:. Enable compression of a log file as follows. You must be an administrator to perform this procedure. This is a simple way to lower disk usage. It is not a final solution, however, because disk usage still grows over time, and could eventually fill up the hard drive.

If the folder already contains a significant amount of data, it could take the computer a while to compress its contents. Also note that this one-time process could slow down the computer during the initial compression, so if this is a production server, perform this operation during off-peak hours to prevent service degradation.

The folder is configured in the Directory property on the Logging page for either the server or an individual site. To lessen the problem of log disk usage, you can move your IIS log files to a folder on another server that has more space. This server can either be in the same domain as the local IIS server, or a different domain.

You can save log files remotely either for the entire server or for individual Web sites. This solution can help the security of the system, because if a local hard drive crashes, the log data is still available on remote storage. In addition, the log files can be consumed by analysis systems. Create a log-file directory on a remote server that is in the same domain as your local Web server running IIS. In the folder's Properties page, on the Sharing tab, click Share so that the directory is shared.

On the Security tab, assign groups and users with the appropriate permissions. Ensure that the appropriate groups and users are able to read and write to the log files.

For more information, see Configuring Permissions for Remote Logging. Double-click Logging. In the Directory text box, enter the full UNC path of the directory that you created on the remote server. In the Actions pane, click Apply , and then click OK. All Web sites within the directory should begin logging data to the remote share. For more information, see Remote Logging. You can control disk usage of log files by running a script that automatically deletes log files that are older than a certain age.

Running this script in a scheduled task will keep the problem of a disk filling up under control without constant maintenance. The following VBScript will check the age of each log file in a folder and will delete any log file older than a specified age. To customize the script for your purposes, simply change the name and path of the folder in line 1 of the script, and change the maximum age to the desired value in days, in line 2. The script above will scan all subfolders, so it will process logs for ALL sites in and under the folder specified.

If you want to limit the process to just a single site, change the path appropriately. To run the script manually, execute the following script in an administrator command line: cscript. Using a script to delete log files is a long-term, reliable solution to the problem of log files consuming disk space. This information is stored in the IIS log file, which is convenient for website administrators to grasp the web page accessed and iis server operation.

If a webpage is maliciously accessed such as injected into a database , there will be a corresponding record in the log file, and you can see what code the injector uses to inject it, which is convenient for analyzing website vulnerabilities.

IIS logs location are there? Windows system has a special folder to save IIS logs. Click on your site within the tree view or double click on it within the grid view on the right side. Double click on the Logging icon to open the logging settings screen. On the logging settings screen, you can find where your IIS log files are located in the Directory field. Navigate to the IIS log files location listed in the directory field. Withing the folder, you will find subfolders for each site configured with IIS.

The number at the end of the folder name corresponds to your site ID mentioned in step 2 above. If you are using Azure App Services, you know that they are very different than using and managing your own Windows Server. For Azure App Services you have first to ensure that web server logging is enabled. We have a great blog post dedicated to all of the log files for your Azure App Service. To access your log files, you will need to use Remote Desktop to connect to an individual server.

The files are stored in a weird file path similar to the one shown here:. If you need to view IIS logs across all of your application instances, you will want to use a log management system, like Retrace. This allows you to aggregate all of your logs together in one centralized location.
