CloudBees CD/RO integration to nagios

The plugin interacts with the Nagios’s command-line tool, the Nagios utility allows you to perform different actions getting the same results that you would get from the web-based interface.

EC-Nagios implements the most important actions to manipulate Host and Host Groups. It allows the enabling and disabling of Host and Host Groups.

CloudBees CD/RO itself provides some advantages like parameters checking, easy functionality selection using only check boxes, combo buttons, historical log reports, procedure duration statistics, simple credentials attachment, real time analysis of the log been generated, among others.

There are two issues to take into account, CloudBees CD/RO in this particular case is unable to get historical log reports and all the actions associated with this because of the way Nagios works. These also means that the user must be really careful when writing the parameters, because there is no way to know if the procedure goes wrong or right.
