NConf is an open source tool for configuring the Nagios network monitoring system (and its fork Icinga). It is mainly targeted at sysadmins who are looking for a more convenient way of managing their Nagios configuration files through the use of a graphical user interface, as opposed to maintaining the configuration files with a text editor.
NConf allows central management of a distributed monitoring environment. It also offers various enterprise-like features such as LDAP authentication, a database API and configuration deployment over secure protocols ( SCP, HTTPs). An import mechanism for importing existing configuration files is also available.
NConf is written mainly in PHP and Perl. All data is stored in a MySQL database. Dependencies for NConf are: Nagios, Apache web server, PHP, Perl, and MySQL.
