Medical Device Telemetry API Monitoring Automation

Create a comprehensive Bash monitoring script that polls multiple medical IoT device APIs, collecting real-time telemetry data from wearable health monitors. The script should parse JSON responses, validate critical health metrics against predefined thresholds, generate immediate alerts via SMS/email for abnormal readings, and maintain a rolling 30-day log of device performance and patient interactions. Implement robust error handling and support multiple device manufacturer APIs.
