This assumes you have installed Ansible Tower and are familiar with the ansible-playbook command.

The "- debug" option can be used to print output to the console. In this example, "Hello World" will be printed.

- debug: msg="Hello World"

When the play is run, the following should be produced.

TASK [debug]
ok: [server1.example.com] => {
    "msg": "Hello World"
}

Here is now to print stdout, stderr, and return code.

---
- hosts: all
  remote_user: root
  tasks:
    - name: ps command
      shell: ps
      register: out

    - debug: msg={{ out.stdout }}
    - debug: msg={{ out.stderr }}
    - debug: msg={{ out.rc }}
