FTP Logging Options <log>

Overview

The <system.ftpServer/log> element specifies the global log settings for the FTP service. More specifically, the attributes on the <system.ftpServer/log> element specify the following options:

• centralLogFileMode - This attribute specifies whether the FTP service should use central logging (per-server) or site logging (per site).

  • If you specify central logging, a single log file will be kept for all of your FTP sites.
  • If you specify site logging, each FTP site will write to individual log files.

• logInUTF8 - This attribute specifies that log files should be encoded in UTF8 format.

When you specify central logging, you can use the <centralLogFile> child element to configure the options for central log file.

Compatibility

Version	Notes
IIS 10.0	The <log> element was not modified in IIS 10.0.
IIS 8.5	The <log> element was not modified in IIS 8.5.
IIS 8.0	The <log> element was not modified in IIS 8.0.
IIS 7.5	The <log> element of the <system.ftpServer> element ships as a feature of IIS 7.5.
IIS 7.0	The <log> element of the <system.ftpServer> element was introduced in FTP 7.0, which was a separate download for IIS 7.0.
IIS 6.0	The <system.ftpServer> element and its child elements replace the IIS 6.0 FTP settings that were located in the LM/MSFTPSVC metabase path.

Note

The FTP 7.0 and FTP 7.5 services shipped out-of-band for IIS 7.0, which required downloading and installing the modules from the following URL:

https://www.iis.net/expand/FTP

With Windows 7 and Windows Server 2008 R2, the FTP 7.5 service ships as a feature for IIS 7.5, so downloading the FTP service is no longer necessary.

Configuration

The <system.ftpServer/log> element is configured at the global level in ApplicationHost.config.

Attributes

Attribute	Description
centralLogFileMode	Optional enum attribute. Specifies whether the FTP service should use central logging (per-server) or site logging (per-site). Attribute Description Site Specifies that each FTP site will write to individual log files. The numeric value is 0. Central Specifies that a single log file will be kept for all of your FTP sites. The numeric value is 1. The default value is Site.
logInUTF8	Optional Boolean attribute. Specifies whether IIS should log all strings for the FTP server in UCS Transformation Format 8 (UTF-8). This setting applies to text-mode logging for all of the sites on the FTP server. The default value is true.

Child Elements

Element	Description
centralLogFile	Optional element. Specifies the settings for the central log file.

Note

An unused element named <customLogging> was declared in the FTP 7.0 schema, but this was removed from the FTP 7.5 schema and should not be used.

Configuration Sample

The following configuration example enables central file logging for the FTP service.

<system.ftpServer>
   <log centralLogFileMode="Central">
      <centralLogFile enabled="true" />
   </log>
</system.ftpServer>

Sample Code

The following examples enable central file logging for the FTP service.

AppCmd.exe

appcmd.exe set config -section:system.ftpServer/log /centralLogFileMode:"Central" /commit:apphost

appcmd.exe set config -section:system.ftpServer/log /centralLogFile.enabled:"True" /commit:apphost

Note

You must be sure to set the commit parameter to apphost when you use AppCmd.exe to configure these settings. This commits the configuration settings to the appropriate location section in the ApplicationHost.config file.
