  This monitor allows to test the functionality of the link:http://freeradius.org/rfc/rfc2865.html[RADIUS] service.
  The availability is tested by sending an _AUTH_ packet to the host.
  If a valid _ACCEPT_ response is received, then the _RADIUS_ service is _up_ and considered as available.
  
  IMPORTANT: To use this monitor it is required to install the _RADIUS_ protocol for OpenNMS.
