I’ll give a brief introduction to a few of the addons that I’ve developed for Centreon Engine…



NRPE is an addon that allows you to execute plugins on remote Linux/Unix hosts. This is useful if you need to monitor local resources/attributes like disk usage, CPU load, memory usage, etc. on a remote host. Similiar functionality can be accomplished by using the check_by_ssh plugin, although it can impose a higher CPU load on the monitoring machine - especially if you are monitoring hundreds or thousands of hosts.

The NRPE addon and documentation can be found at



NSCA is an addon that allows you to send passive check results from remote Linux/Unix hosts to the Centreon Engine daemon running on the monitoring server. This is very useful in distributed and redundant/failover monitoring setups.

The NSCA addon can be found at



NDOUtils is an addon that allows you to store all status information from Centreon Engine in a MySQL database. Multiple instances of Centreon Engine can all store their information in a central database for centralized reporting. This will likely serve as the basis for a new PHP-based web interface for Centreon Engine in the future.
