Collect IIS Logs
Logs from internet information services are useful for troubleshooting, reporting and also security scenarios.
If you have more specific requirements aside from just collecting the IIS Logs and have facets on the common fields in the log, then please let us know.
This has been enabled! Visit the log management page and in the ‘configure’ section you’ll find the option to turn on IIS logs collection. Enjoy!
