I'm also deploying native JTI at the moment on some MX devices. I have
got OpenNTI working, and managed to get traffic graphs working in
Grafana using it.

I'm now trying to set each part of this up individually without
Docker, for a more production ready setup. I've been following this
blog:

I'm trying to get my head around the difference between fluentd and
Telegraf, what does each one do, and why are both of these required?
