pfSense » pfSense Packages

Hi,

I'm trying to use the Wireguard plugin for telegraf, more info on the plugin here,
https://github.com/influxdata/telegraf/tree/master/plugins/inputs/wireguard

So, I added to my telegraf "Additional configuration for Telegraf"

[[inputs.wireguard]]

But, if I then run a test (output to shell),

telegraf --test --config /usr/local/etc/telegraf.conf | grep -i wireguard

No output (just the Telegraf "header". So, I checked the Wireguard interface, with wg show, and get,

interface: tun_wg0

Adding this interface specifically to the pfSense telegraf config, it's now,

[[inputs.wireguard]]
  devices = ["tun_wg0"]

Telegraf (test) does report an output at this point, but it's not happy :-(,

2021-12-30T23:44:48Z W! [inputs.wireguard] No Wireguard device found with name tun_wg0

So something isn't quite right. I saw a similar thing before in Linux, thinking this may be related? It was tied there to user vs. kernel space implementation and access ... some links that may help here.

Thoughts?

Thanks!
