Обновил всё, перезапустил сервер, включаю мониторинг через меню bitrixvm получаю ошибку, в журнале задач.

Вот так выглядит ошибка в консоли:

to retry, use: --limit @/etc/ansible/monitor.retry

Решение проблемы с запуском мониторинга bitrixvm:

В файле:

/etc/ansible/roles/monitor/tasks/install.yml

перед задачей - name: nagios - create commands and default tests definitions в строке 365 необходимо добавить:

- name: nagios - create /etc/nagios/conf.d directory
  file: path=/etc/nagios/conf.d
    state=directory
    owner={{ nagios_server_user }} group={{ nagios_server_group }}
    mode=0750
  tags: configure_monitor_servers
  when: "'bitrix-mgmt' in group_names"

После внесения изменений, снова пробуем активировать мониторинг.
