atoti-server-spring-boot-admin

Create a comprehensive monitoring dashboard for a fleet of microservices using Spring Boot and Python. Your task is to develop a mini-application that leverages the 'atoti-server-spring-boot-admin' package to monitor the health and performance of these services. This application will serve as a centralized hub where system administrators can track key metrics such as uptime, memory usage, CPU load, and error rates for each service instance.

### Step-by-Step Development Guide:
1. **Set Up Your Environment:** Begin by setting up your development environment with Python and Java installed. Ensure you have the necessary tools like Maven for building Java applications and pip for managing Python packages.
2. **Spring Boot Services Setup:** Create a few sample Spring Boot services that mimic real-world applications. Each service should have endpoints that return simulated data about its status (e.g., uptime, memory usage).
3. **Integrate Spring Boot Admin:** Use the 'atoti-server-spring-boot-admin' package to integrate Spring Boot Admin into one of your Spring Boot services. This service will act as the dashboard server, providing an interface for monitoring other services.
4. **Dashboard Customization:** Customize the Spring Boot Admin dashboard to display specific metrics that are relevant to your services. For example, you might want to create custom dashboards or widgets that show graphs of memory usage over time.
5. **API Integration:** Develop a simple Python script that queries the Spring Boot Admin API to fetch live metrics from the monitored services. Display these metrics in a human-readable format, such as printing them to the console or writing them to a file.
6. **Alerting System:** Implement a basic alerting system within your Python script that triggers notifications (e.g., via email or SMS) when certain thresholds are breached (e.g., if a service's uptime drops below a specified percentage).
7. **Testing and Deployment:** Test your application thoroughly to ensure all components work as expected. Deploy your Spring Boot services and the dashboard server to a staging environment before moving to production.

### Suggested Features:
- Real-time metric updates on the dashboard.
- Historical data storage for trend analysis.
- Customizable alerts based on different metrics.
- Support for multiple user roles with varying levels of access.
- Integration with external logging services for error tracking.

### Utilizing 'atoti-server-spring-boot-admin':
This package simplifies the integration of Spring Boot Admin into your application, allowing you to focus more on customizing the dashboard and less on plumbing. It provides essential resources and configurations needed to get started with monitoring Spring Boot applications efficiently.
