I tried to use Ansible service module to restart a service but I got an error.
tasks:
- ini_file: dest=/etc/dd-agent/datadog.conf
section=Main
option=use_mount
state=absent
register: ddagent
- service: name='datadog-agent' state=reloaded
when: ddagent.changed
This generated this error: ERROR: change handler (restart datadog) is not defined
I know that an alternative is to execute:
- command: "service datadog-agent restart"
Still, in this case what's the purpose of the service module?

Use systemctl restart ansible-tower to restart services on clustered environments instead. Also you must restart each cluster node for certain changes to persist as opposed to a single node for a localhost install.
Take this code: - hosts: localhost become: yes tasks: - name: Stop and Start ssh service: name: ssh state: stopped and check the status using "service ssh status" .
How to stop a service. Set the name parameter to the service name and the state parameter to stopped to stop a service. If the service is not running, Ansible will do nothing.
If you're checking services, you can do it the Ansible way by running the service_facts module and then checking ansible_local. services["apache2"]. status as well.
You should add the following code:
handlers:
- name: restart datadog
service: name=datadog-agent state=restarted
The problem that you are facing is that you don't have the handler defined. This will do the job
