Default monit_eventqueue_dir is not set

[mishawakerman]

README says monit_eventqueue_dir defaults to /var/lib/monit/events however this is not the case in defaults/main.yml.

This means the monitrc.j2 template never adds the set eventqueue block:

{% if monit_eventqueue_dir is defined %}
set eventqueue
  basedir {{ monit_eventqueue_dir | default('/var/lib/monit/events') }}
  slots {{ monit_eventqueue_slots | default(100) }}
{% endif %}

Which means alerts don't send.
