The nrdpd program is used as a passive monitoring agent for Nagios.  It
will use regular Nagios plugins to perform system checks and submit those
results to your monitoring server(s) via the NRDP protocol.

This package contains both the nrdpd service and a Python library that
you can integrate with.

The full documentation (https://hopliteind.github.io/nrdpd-daemon/) has details
on the API as well as configuration.
