Hm, at least there has not been any customer requests for that, and
quite frankly it is the first time I've ever heard of it, but I'm also
not really into metrics. But as it looks like Prometheus is too big for
them to ignore it, so you might be lucky with that:

https://github.com/influxdata/telegraf/blob/master/plugins/inputs/prometheus/README.md

All in all I don't think there are any plans, and if that input plugin
works then one should use that. Technically it would be almost trivial
to recycle the Prometheus components (data caches, ...) and just
generate the Telegraf output I guess.

Seeing that Telegraf can also process json, that was a plugin I always
had on my mind when I started drbd-reactor. Like a event triggered
version of `drbdsetup status --json`. That one might come in handy for
all sorts of things that want to process DRBD events as json or anything
else that Rust's serde can serialize. I did not do that so far because
it obviously needs deciding on a representation of the data. And I'm not
sure (actually I am) if I like the one drbdsetup uses (i.e., lists where
it actually is a hashmap, very weird key names,...). But that plugin is
more realistic than a dedicated Telegraf one I'd say.
