Nagios Reader to Centreon CLAPI

"Nagios Reader to Centreon CLAPI" is a free and open source project to analyse Nagios CFG configuration files and to transform monitoring configuration to Centreon CLAPI command in order to import configuration into Centreon web interface.

Prerequisites

First of all you need a CES server installed and ready to use. Please see the document on document.centreon.com to install a Centreon server based on CES.

Installation

This script uses the Perl-Nagios-Object library to read CFG files. To install it please follow this steps on your Nagios(R) server:

$ yum install perl-Module-Build perl-Test-Exception perl-Test-NoWarnings perl-List-Compare
$ cd /tmp
$ wget http://search.cpan.org/CPAN/authors/id/D/DU/DUNCS/Nagios-Object-0.21.20.tar.gz
$ tar xzf Nagios-Object-0.21.20.tar.gz
$ cd Nagios-Object-0.21.20
$ perl Build.PL
$ ./Build
$ ./Build test
$ ./Build install

Note : perl-List-Compare is from EPEL repo for CentOS/Red Hat

Usage

On a fresh CES server the default poller is named "Central". If you rename it or if you want to link this Nagios configuration to a predifined poller you have to change the poller name on line 65

my $default_poller = "Central";

To display help use the command:

$ perl nagios_reader_to_centreon_clapi.pl --help

    -V (--version)     Show script version
    -h (--help)        Usage help
    -C (--config)      Path to nagios.cfg file
	-S (--servcies-hg) To keep services by hostgroups definition

Note : By default services by hostgroups will be transformed. A template of service will be created using old service definition and a unitary service by host (for all hosts linked to the hostgroup) will be created linked to the previous service template.

To run the script please use the following command:

$ perl nagios_reader_to_centreon_clapi.pl --config /usr/local/nagios/etc/nagios.cfg > /tmp/centreon_clapi_import_commands.txt

Export the file /tmp/centreon_clapi_import_commands.txt on your CES server.

Run the following command to import configuration into Centreon on your CES server:

$ /usr/share/centreon/www/modules/centreon-clapi/core/centreon -u admin -p @PASSWORD -i /tmp/centreon_clapi_import_commands.txt
