guide for troubleshooting (specifically Wireguard) via CLI?

[granute]

I see a few threads here which look pretty useful for helping validate some (too?) clever things I'm trying to do with Wireguard site-to-site VPNs and I will dive into those shortly. However, what I'm not finding is a lot of collateral on how to do low-level troubleshooting at the CLI. That is going to be the highest fidelity approach in some situations because the management console presents only a subset of the available info for debugging.

Does anyone have any suggestions on a resource? Primarily just the usual FreeBSD docs?

thx

What low level tshoot are you looking for. E.g what is your idea of low level tshoot for this?

OPNsense GUI, provides enough transparency + logs specific to WG to tshoot it usually.
