Hardware and software requirements for the Splunk Add-on for Microsoft IIS

Splunk admin requirements

To install and configure the Splunk Add-on for Microsoft IIS, you must be member of the admin or sc_admin role.

Microsoft IIS setup requirements

You must enable IIS logging for the Web server from which you want to collect data and use the W3C log file format. Refer to the Microsoft IIS documentation for information about configuring logging in IIS. For more information, search for “Configure Logging in IIS” on the Microsoft documentation.

If you use the IIS Advanced Logging Module and you plan to use the the ms:iis:auto source type for automatic index-time field extraction, do not include the EndRequest-UTC and BeginRequest-UTC fields when you configure the logging fields in the IIS Advanced Logging module. These fields are not W3C-compliant. For more information about configuring fields using the Advanced Logging Module, search for “Advanced Logging for IIS - Custom Logging” in the Microsoft documentation.

Splunk platform requirements

Because this add-on runs on the Splunk platform, all of the system requirements apply for the Splunk software that you use to run this add-on.
