Description: 
Nagios Remote Data Processor (NDRP) is a flexible data transport 
mechanism and processor for Nagios. It is designed with a simple 
and powerful architecture that allows for it to be easily extended 
and customized to fit individual users needs. It uses standard ports 
protocols (HTTP(S) and XML) and can be implemented as a replacement for NSCA.
