Official documents See http://docs.ansible.com/ansible/dev_guide/developing_api.html

Take the official example and revise it as follows

If you need a unified output you can override

V2_runner_on_failed (self, result, ignore_errors=False) V2_runner_on_ok (self, result) v2_runner_on_skipped (self, Result) v2_runner_on_unreachable (self, result) v2_runner_on_no_hosts (self, Task)
