In a similar way than the skippy plugin hides skipped events in the stdout log of an Ansible run, this plugin displays only changed events.
It also hides task name if no changes are made.
This is an example output using this plugin:
PLAY [all] ***********************************************************************************************************
TASK [rabbitmq : Configure RabbitMQ users] ***************************************************************************
changed: [rabbitmq1.example.org] => (item={u'username': u'myuser', u'password': u'mypass'})
changed: [rabbitmq2.example.org] => (item={u'username': u'myuser', u'password': u'mypass'})
changed: [rabbitmq3.example.org] => (item={u'username': u'myuser', u'password': u'mypass'})
PLAY RECAP ***********************************************************************************************************
rabbitmq1.example.org : ok=2 changed=1 unreachable=0 failed=0
rabbitmq2.example.org : ok=2 changed=1 unreachable=0 failed=0
rabbitmq3.example.org : ok=2 changed=1 unreachable=0 failed=0
In your ansible.cfg file add:
stdout_callback = changes
callback_plugins = ./plugins/callback
Download this plugin in ./plugins/callback:
mkdir -p plugins/callback
wget https://raw.githubusercontent.com/paulRbr/ansible-changes-stdout-callback/master/changes.py -O plugins/callback/changes.py
