First, love the recent addition of Zerotier. Thought I'd try campaigning for a native build of telegraf or something similar. We've been using push-based metrics/streaming telemetry from Azure Sonic, OpnSense, and generic Linux firewalls to great effect for a while now. Would absolutely love to be able to deploy entire edge networks that auto-report metrics back.
Been building my own scripts (quite ugly at the moment), inspired by this:

Unfortunately, been having a bear of a time with some of the mods we need in production.
I feel that push-based metrics represent a huge leap forward in simplifying large numbers of network devices, especially those distributed through diverse networks (MSP or enterprise remote-worker gear)
