Summary

In this chapter, we have seen how we can teach Ansible to send notifications to other systems and people. You learned to send notifications through a variety of systems, including email and messaging services, such as Slack. Finally, you learned how to prevent Nagios from sending unwanted notifications about system health during periods when you are operating it.

In the next chapter, we will learn how to create a module so that you can extend Ansible to perform any kind of task.
