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 Centreon server installed and ready to use. Please see the document on htt://document.centreon.com to install a Centreon server based on ISO or RPM.

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

To run the script please use the following command:

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

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

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

$ /usr/share/centreon/bin/centreon -u admin -p @PASSWORD -i /tmp/centreon_clapi_import_commands.txt

Notes

• Services by hostgroups will be transformed : a template of service will be created using old service definition, and a unitary service will be created for all hosts linked to the hostgroup using the newly created service template.
• Hostgroups exclusions (i.e. hostgroup_name !Windows) won't be taken into account.
• Using filters may provoque errors at CLAPI import because of the contacts definition on several objects being the full name instead of the login/alias as CLAPI intend it to be.
