I'm currently considering the alarm path for a scale out architecture and got stuck on a couple points. Not sure if I'm overthinking or overlooking something more simple so any pointers are always welcome.
Current Setup:
- Three-tiered architecture: 20x Edge Gateways > Back End Gateway > 2x Front End Gateways
- Using MQTT between Edge and Back End
- Edge Gateways are currently for data collection, but some will likely have perspective in the future.
At the moment, I can see two possible alarm paths.
- Edge-Based Alarms:
- Configure alarms on edge gateway tags
- Use remote tag providers to pass alarms across the network
- Challenge: Each Front End would need a remote tag provider connection to each Edge.
- Pro: Easier to manage
- Con: May not scale well with many Front Ends and Edge Gateways
- Con: Could complicate future edge-based Perspective implementations
- Back End-Based Alarms:
- Create alarms on Back End Gateway using reference tags from MQTT
- Pro: More centralized approach
- Con: May limit future edge-level Perspective deployments
I think MQTT Alarms wouldn't be applicable for me as its not MQTT to the front end, and I have a hunch they are less flexible with alarm notifications?? (happy to be wrong on that though).
