IIS Advanced Logging provides tremendous flexibility in logging user requests and client data. Advanced Logging doesn't assume what's important to you. Instead, it provides enough control for you to specify what fields are important, add additional fields with ease, and provide policies around log file rollover and request filtering. You can log any of the HTTP request/response headers, IIS server variables, and client-side fields with simple configuration in IIS Manager.
The IIS Advanced Logging is an extension for Internet Information Services (IIS) 7 is no longer available. We recommend Enhanced Logging for IIS 8.5.
The following prerequisites must be fulfilled to install IIS Advanced Logging:
The following options are available for installing IIS Advanced Logging:
Log definition. Defines the fields that are logged in each log file generated on the web server. It also sets additional options, such as log file rollover interval, base log file name, and so on.
Global logging fields. Advanced Logging maintains a master list of logging fields (the global logging fields list) that an administrator can add to log definitions in IIS Manager. Custom logging fields can be added to the global logging fields list (and by extension, to log definitions) using the IIS management interface. Custom logging fields can be added from the following source types:
This section contains the following topics about the IIS Advanced Logging UI:
IIS Advanced Logging can be configured for servers, websites, and directories in IIS Manager. To open the Advanced Logging feature, click the server, website, or directory in the Connections pane, and then double-click the Advanced Logging icon on the Home page.
By default, IIS Advanced Logging is disabled after you install it. To enable the feature so that it can handle log messages from other web server components, open it at the server level in IIS Manager, and then in the Actions pane, click Enable Advanced Logging.
To disable the feature at a later time, open it at the server level in IIS Manager, and then in the Actions pane, click Disable Advanced Logging.
By default, client logging in the Advanced Logging feature is disabled after you install it. To enable client logging in the Advanced Logging feature so that it can handle client log messages that are received as XML data via HTTP POST messages, open the Advanced Logging feature at the server level in IIS Manager, and then in the Actions pane, click Enable Client Logging.
To disable client logging at a later time, open the Advanced Logging feature at the server level in IIS Manager, and then in the Actions pane, click Disable Client Logging.
The Advanced Logging feature displays all of the log definitions that are available on the server on the server Home page in IIS Manager. The following figure displays the log definition %COMPUTERNAME%-Server, which is installed by default and captures some fields of interest from a content delivery perspective.
To view the fields that are included in this log definition, click the log definition name, and then in the Actions pane, click Edit Log Definition. This opens the Log Definition feature page for the selected log definition, as shown in the following figure:
The global logging fields list contains all of the logging fields that can be added to log definitions. To view the global logging fields list, open the Advanced Logging feature at the server, website, directory, or application level in IIS Manager, and then in the Actions pane, click Edit Logging Fields.
This action opens the Edit Logging Fields dialog box, which displays the logging fields that are included in the default installation of IIS Advanced Logging.
To learn more about adding custom logging fields to the global logging fields list, see Adding Custom Logging Fields.
This section describes how to add a custom logging field to the global logging fields list. In the following examples, we'll use a custom HTTP response header author as the custom logging field. This custom response header returns the webpage author's name in the response to clients.
To add a custom logging field to the global logging fields list, do the following:
This section describes how to use the custom logging field Author that we added in the previous section in a new log file. To do this, we need to create a new log definition:
When you access a webpage hosted by the server, you should see Author being logged, along with the other logging fields that you selected in the previous section, in the log files that are created. By default, log files for the server and all websites are stored in %SystemDrive%\inetpub\logs\AdvancedLogs. You can change this "global" log directory for the server and for websites and you can also specify a unique log directory for each website on your server.
This section contains the following procedures:
