Feature Request: Optical Transceiver / DDM Diagnostics view

[Imamdienul]

Hi team, love what you're building with VyManager! 🙌

Would it be possible to add a page/panel showing SFP/SFP+ transceiver diagnostics (DDM) for ethernet interfaces? This is the CLI equivalent:

show interfaces ethernet <if> transceiver

It returns useful info like:

• Transceiver type, vendor, part number, serial number
• Laser bias current, TX/RX optical power (mW/dBm)
• Module temperature & voltage
• Alarm/warning thresholds and current status

This would be a great addition to the interface detail page — especially the alarm/warning flags, since those are early signs of a failing optic or a fiber problem before the link actually drops. A small badge/indicator (green/yellow/red) per interface row on the interfaces list would already be super helpful, with a full detail view when you click in.

I dug into the backend a bit — since show op-mode commands are already used via pyvyos (e.g. for the config cache), this looks addable as a new endpoint (GET /vyos/ethernet/{interface}/transceiver) that parses the CLI output into JSON, plus a frontend panel that polls it every few seconds. Happy to help test this if someone starts on it, or point to what I found if it helps.

Is this something that fits the roadmap? Would also be happy to open a PR if a maintainer can confirm the approach (parser location, whether it should live under vyos_service.py or a new vyos_parsers/ module) before I start.

Thank you for your FR.

Please open a PR.

Backend routers (e.g. /interfaces/ethernet/{if}/transceiver) live in /backend/routers/interfaces/ethernet.py

Parsers maybe created in a seperate file within /backend. For this matter, please have a look at files like ipsec_status.py or monitoring_commands.py

We'll put this in another structure later, but for now, just put it there.

Make sure to follow CONTRIBUTING.md guidelines.

Thank you for your contribution! We're looking forward to it.
