Authentication for metric pushes

[fire]

How would you recommend forcing all clients to be authenticated?

A tls mutal authentication proxy would work, but a password and username on a regular tls would be ideal. Establishing a PKI infrastructure is not trivial.

What do you recommend?

Mostly not, the protocols implemented don't provide authentication support as far as I know. If that is a concern a secure network is a way to go or a VPN? Basically, it's up to whoever deploys it.

I believe the influxdb protocol allows password and username.

You can check which ones have authentication via https://github.com/influxdata/telegraf#output-plugins

For example:

https://github.com/influxdata/telegraf/tree/master/plugins/outputs/influxdb has password and username and mutal auth.

Ah I didn't know that. Still it doesn't warrant the extra work involved when no one is using it, influx is just one of the many protocols so it'd be quite the special case.

That said if you fancy authentication go ahead, I've no objections to it.
