Ansible: playbook-wide role_names

Question

I use following condition to check whether certain role is present: {% if "openmap" in role_names %}. However it looks like role_names contains only role names that are executed on the current host. I came to this conclusion because I have following code in my nginx.conf.j2:

...
    {% if "monitoring" in role_names %}
        # monitoring proxying if the role is enabled
        location = /monitoring {
         proxy_pass http://{{ groups['monitoring_server'][0] }}:{{ external_grafana_port | int + group_port_offset | int }};
    }
    {% endif %}
...

and that part is skipped despite the fact that my yaml file that I run with ansible-playbook has this:

...
- hosts: monitoring_server
  become: yes
  roles:
    - role: monitoring
...

I would like to check whether certain role is present in the whole playbook, even though it will not be executed on the current host but rather on another one. How can I do it?
