[Feature Request] Please set TUN/TAP driver virtual IF speed attribute to the speed of the underlying physical IF or make it configurable #2271

Open sgofferj opened 4 months ago

sgofferj commented 4 months ago

I have ZT running on my Linux home server. The ZT interface reports an interface speed of 10Mbit/s. The physical interface is a GBE and my internet connection is 100MBit. That leads to Zabbix, which is monitoring my home server, to VERY OFTEN scream at me "Problem: Interface ztksetbnx7: High bandwidth usage (>90%)", because of course the rates are quite often over 9MBit/s. This could be avoided if ZT would set the speed attribute for the tunnel interface to the value of the underlying physical interface, allow the admin to configure what speed should be reported or just set the speed attribute to 1000.

Which underlying physical interface? :)

There are probably 1 or 2 open issues in here for this

I checked the issues but nothing jumped at me.

If there's more than 1 physical interface, it could be configurable maybe?

The thing is that most monitoring systems get very unhappy if interfaces are (apparently) (over-) saturated and the corresponding Telegram, Matrix, Slack, ... rooms start to fill up with alarms which tends to make phones very noisy, which tends to antagonize or even aggravate wives/girlfriends.

Aggravated wives/girlfriends tend to be much less tolerant of home labs or home servers...
