  Ya's good.

  Sure.

  You didn't read that in the FreeRADIUS documentation.  There is no secret documentation / source code.  When you download FreeRADIUS, it includes everything.  And there is no Prometheus module in FreeRADIUS.

  So... download it from the external site, and configure it using the external documentation?  i.e. ask them how to configure the software that they wrote.

  I haven't used Prometheus.  Maybe other people have used it.
