Return values are the key feature for monitoring and managing task execution. An administrator can determine the status of each action and run other tasks accordingly, either to fix, improve, or follow up on the bigger job. Ansible modules are fitted with a variety of return values. Each module will have the common values and some extra specific ones for the role performed by the module. These extra return values can be used for numerous functionalities. In Ansible, most return values are used as input for playbook conditions and loops. This scripting allows the pipelining of actions and tasks to achieve an automated configuration management. Ansible basically collects all the useful output data about the action performed by the module and arranges it into variables presented as return values.
