-
Communication Contract: Requesting Data: There is no explicit request mechanism. The subscriber automatically receives updates. Receiving Data: Format: Timestamp string in the format YYYY-MM-DD HH:MM:SS Frequency: Every 1 second Protocol: ZeroMQ PUB/SUB Port: 5555 Topic: No specific topic (empty string to subscribe to all)
-
Example Usage:
Python
import zmq
context = zmq.Context() subscriber = context.socket(zmq.SUB) subscriber.connect("tcp://[Your Microservice IP or Hostname]:5555") subscriber.setsockopt_string(zmq.SUBSCRIBE, "")
while True: timestamp = subscriber.recv_string() print(f"Received: {timestamp}")

Mitigation Plan:
Status: The microservice is fully functional. Access: The code for this microservice is available on GitHub: https://github.com/ICANDIGITAL/ Teammates can either run it locally or you can provide a hosted instance if they prefer. Contingency: If my teammate cannot access your microservice: They should immediately contact me via Slack. My availability is 9:30 am to 6:00 pm (Monday through Friday) EST. The deadline for notification is 05/27/2024, preferably within 48 hours. Additional Notes: Ensure all teammates have ZeroMQ installed in their Python environment (pip install pyzmq). If you are hosting the service, please provide the IP address or hostname where it is running. Consider potential network issues or firewalls that might block communication and discuss solutions in advance. For robust error handling, all teammates should incorporate timeout mechanisms and retry logic in their subscriber code.
