&#x20;warning when happening the problems and also when the problems are solved. The
&#x20;Hosts are equipment and Services are resources offered by the equipment.

The objective of this functionality is to <font color="#3b9f0f">**register and maintain the managers that
 will be responsible for monitoring the configuration items and event occurrences**</font>
&#x20;captured from the Nagios. It allows the user to inform when the Manager will be
&#x20;processed, which configuration items it will manage, and the actions to be taken
&#x20;automatically.

This feature provides a variety of actions, such as <font color="#3b9f0f">**including, changing, and
 deleting a Nagios manager**</font>.
