This application monitors changes in a dataset stored in InfluxDB and publishes notifications via MQTT when new data is available. Additionally, it provides a REST API endpoint to retrieve the latest data and its change status.
Features
- Real-time Data Monitoring: Monitors changes in a dataset stored in InfluxDB in real-time.
- Notification via MQTT: Publishes MQTT messages when new data is detected, enabling real-time notifications.
- REST API Endpoint: Provides a simple REST API endpoint to retrieve the latest data and its change status.
- Persistence: Stores the last known data in a JSON file for comparison during subsequent runs, ensuring continuity in data monitoring.
Potential Use Cases
- IoT Device Monitoring: Monitor sensor data from IoT devices and receive notifications when values exceed predefined thresholds.
- Server Performance Monitoring: Track server metrics such as CPU usage, memory usage, and disk space and receive alerts when anomalies are detected.
- Environmental Monitoring: Monitor environmental factors such as temperature, humidity, and air quality in smart buildings or agriculture settings.
- Log Monitoring: Monitor log data from applications, servers, or network devices and receive alerts for specific patterns or errors.
Conclusion
This application provides a versatile solution for real-time data monitoring and notifications, suitable for various use cases across industries. By leveraging the power of InfluxDB, MQTT, and Node.js, developers can build robust and scalable data monitoring systems tailored to their specific needs.
