That sounds fair.

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:

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.
