📊 Статус компонентов:
|
||||
• Служба: ✅ {{ grafana_active.stdout }}
|
||||
• Порт 3000: {{ '✅ открыт' if port_check is defined and port_check.state == 'started' else '❌ закрыт' }}
|
||||
• API: {{ '✅ доступен (HTTP ' ~ api_check.status ~ ')' if api_check is defined and api_check.status == 200 else '❌ недоступен' }}
|
||||
|
||||
🔗 Доступ:
|
||||
• URL: http://{{ inventory_hostname }}:3000
|
||||
• Логин: admin
|
||||
• Пароль: {{ grafana_admin_password | default('admin') }}
|
||||
|
||||
📋 Для проверки выполните:
|
||||
curl http://{{ inventory_hostname }}:3000/api/health
|
||||
|
||||
💡 Примечание: Первый запуск Grafana занимает время из-за:
|
||||
1. Миграций базы данных
|
||||
2. Установки плагинов по умолчанию
|
||||
3. Инициализации сервиса
|
||||
|
||||
Последующие запуски будут значительно быстрее.
