Trace Failed Requests Logging for a Site <traceFailedRequestsLogging>

The <traceFailedRequestsLogging> element of the <site> element sets the failed request tracing options for site, such as the directory for failed request tracing log files, the maximum number of failed request tracing log files, and whether failed request tracing is enabled.

After you finish the default installation of IIS 7 and later, you must install the tracing role service to use failed request tracing. After you install the role service, you still must enable failed request tracing at the site level, application level, or directory level.

1. On the taskbar, click Server Manager.
2. In Server Manager, click the Manage menu, and then click Add Roles and Features.

     • On the taskbar, click Server Manager, click Tools, and then click Internet Information Services (IIS) Manager.

   • If you are using Windows 8 or Windows 8.1:

     • Hold down the Windows key, press the letter X, and then click Control Panel.
     • Click Administrative Tools, and then double-click Internet Information Services (IIS) Manager.

   • If you are using Windows Server 2008 or Windows Server 2008 R2:

     • On the taskbar, click Start, point to Administrative Tools, and then click Internet Information Services (IIS) Manager.

   • If you are using Windows Vista or Windows 7:

     • On the taskbar, click Start, and then click Control Panel.
     • Double-click Administrative Tools, and then double-click Internet Information Services (IIS) Manager.

2. In the Connections pane, expand the server name, expand the Sites node, then click the name of the site.

3. In the site's Home pane, click Failed Request Tracing... in the Actions pane.

4. In the Edit Web Site Failed Request Tracing Settings dialog box, specify your tracing options, and then click OK.

   

None.

The following configuration sample shows a Web site that has enabled logging for failed request tracing, and ten log files that will be kept as history.

<site name="Default Web Site" id="1" serverAutoStart="true">
   <application path="/">
      <virtualDirectory path="/" physicalPath="%SystemDrive%\inetpub\wwwroot" />
   </application>
   <bindings>
      <binding protocol="http" bindingInformation="*:80:" />
   </bindings>
   <traceFailedRequestsLogging enabled="true"
      directory="%SystemDrive%\inetpub\logs\FailedReqLogFiles"
      maxLogFiles="10" />
</site>

The following code samples show how to enable failed request logging for the Default Web Site, and how to set both the logging directory and maximum number of log files.

appcmd.exe set config -section:system.applicationHost/sites "/[name='Default Web Site'].traceFailedRequestsLogging.enabled:True" /commit:apphost
appcmd.exe set config -section:system.applicationHost/sites "/[name='Default Web Site'].traceFailedRequestsLogging.maxLogFiles:10" /commit:apphost
appcmd.exe set config -section:system.applicationHost/sites "/[name='Default Web Site'].traceFailedRequestsLogging.directory:%SystemDrive%\inetpub\logs\FailedReqLogFiles" /commit:apphost
