Nagios is a network monitoring tool. It can monitor both hosts and services,
warning when happening problems and also when the problems are solved. The
Hosts are equipment and Services are resources offered by the equipment.
The objective of this functionality is to register and maintain the managers that
will be responsible for monitoring the configuration items and event occurrences
captured from the Nagios. It allows the user to inform when the Manager will be
processed, which configuration items it will manage, and the actions to be taken
automatically.
This feature provides a variety of actions, such as including, changing, and
deleting a Nagios manager.
## Before getting started
- [x] Make sure to have previously registered the **CITSmart**
**Event Monitor** connection, time, occurrence category, automatic action and the
**CITSmart** **Inventory connection**.
## Procedure
1. Access the functionality through the main menu `Processes > Event Management > Nagios > Nagios Manager`;
2. Complete the fields available in each area;
3. In the parent configuration item area, it is possible to register the CI in
**CITSmart** with the data of the Host selected. Click on "**Create CI**". Remember
that this registry can only be made if there is no CI with the same Host
identification:
- Enter the data of the child configuration item;
- Conduct a relationship between the Host service and the child configuration
item. Each host service must be related to its respective child
configuration item.
4. Click on "**Save**".
