Information
IIS 8.5 introduces a new logging method. Administrators can now send logging information to Event Tracing for Windows (ETW).
IIS flushes log information to disk, therefore prior to IIS 8.5, administrators do not have access to real-time logging information. Text-based log files can also be difficult and time consuming to process. By enabling ETW, administrators have access to use standard query tools for viewing real-time logging information.
NOTE: IIS 8.5 was not discovered as installed on the target.
