1. **Доступ к сервисам:** 1. **Запуск:**
```bash
docker compose up -d

2. **Доступ к сервисам:**
- Приложение: http://localhost:8080 - Приложение: http://localhost:8080
- Prometheus: http://localhost:9090 - Prometheus: http://localhost:9090
- Grafana: http://localhost:3000 (admin/admin) - Grafana: http://localhost:3000 (логин: admin, пароль: admin)
2. **Дашборды автоматически загружены:** 3. **Дашборды:**
- Spring Boot Application Metrics - Открой Grafana → Home → Dashboards
- PostgreSQL & HikariCP Monitoring - Два дашборда загружены автоматически:
- **Spring Boot Application Metrics** — HTTP, JVM, CPU, GC
- **PostgreSQL & HikariCP Monitoring** — connection pool, база данных
4. **Создай нагрузку для проверки:**
```bash
# Создать задачу
curl -X POST http://localhost:8080/api/tasks \
-H "Content-Type: application/json" \
-d '{"title":"Test","description":"Load test","completed":false}'
