/service/data/metrics does not work

https://help.sonatype.com/repomanager3/system-configuration/capabilities/in-product-analytics-capability says you can go to /service/data/metrics to view the data that is sent to Sonatype.

But navigating to that path just gives a 404 error.

So either the functionality is broken, the documentation wrong, or at least not clear enough where to go to.
