Managing Nagios configuration is a challenge. Nagios X1 helps in this but it is a paid service. But which are the tools , freeware , which can make the Nagios configuration management easy?

What are the other tools and their purpose whicah are recommended in general?

The tool that nagios XI uses purely for config management is called NagiosQL and is available for free over there --> http://www.nagiosql.org/

Another good one is nconf - http://www.nconf.org/dokuwiki/doku.php
