Core: LAGG & VLAN status on dashboard

[darkain]

I'd like to see LAGG & VLAN status on the dashboard under Interfaces (or in some new panel).

In the provided screen shot, COSPIX and LAN interfaces are each VLANs which share a common LAGG interface.

Things I'd like to see on the dashboard (and this list may increase over time, too)

1) VLAN ID
2) Parent LAGG interface
3) LAGG parent adapters
4) The status of each LAGG parent adapter (UP/DOWN, link speed)

For my example, one possible solution would be to replace "Ethernet autoselect" with the parent interface. This would be VLAN-5 on LAGG-1 for example.

Right now, the LAGGs themselves can be added as interfaces under Assign Interfaces page, but once they're added, they display no useful information in the Interfaces dashboard. Instead of "Ethernet autoselect", it would be nice to see all of its parent interfaces as well, along with their link speeds and statuses.

Is there some kind of documentation regarding the development / customizing of widgets?

@botboe unfortunately not, no, it's legacy code, which so-far hasn't been very much on our radar other than performing cleanups and small rewrites.

If your looking for a simple example, this might help https://github.com/opnsense/plugins/tree/master/security/etpro-telemetry/src/www/widgets

The interfaces widget consists of https://github.com/opnsense/core/blob/master/src/www/widgets/widgets/interface_list.widget.php for the static frontend code, which has an update hook here
https://github.com/opnsense/core/blob/f394fed/src/www/widgets/widgets/interface_list.widget.php#L115

which is being served data on intervals from here https://github.com/opnsense/core/blob/master/src/www/widgets/api/plugins/interfaces.inc

using this to update: https://github.com/opnsense/core/blob/f394fed/src/www/widgets/widgets/interface_list.widget.php#L67

Thank you @AdSchellevis, after finishing my radsecproxy-plugin I will give it a try :-)
