What a bizarre claim.

Prometheus scrapes the same text format as OpenMetrics 1.0 and over 700 public exporters use this format, and there are TONS of other non-Prometheus software that consume the exact same text format. Prometheus's biggest competitor, Datadog (which is not open source mind you), consumes it too. I think even Grafana consumes it directly. It's becoming an IETF standard[0].

Would I have preferred JSON over a custom text format like this? Yeah. But to claim an open source project like Prometheus with effectively no business at all is using a text format like this to have vendor lock-in? That's quite a stretch.

I find the GP's claims weird - I've written a relative ton of collectors, exporters, and translators and the format is pretty OK, not worse than most that came before it and better than lots - but I think this relationship is backwards. Prometheus "scrapes OpenMetrics" because OpenMetrics was formal documentation of what Prometheus was already doing for years.

I would not have preferred JSON. That an exposed metric is also a query is also pretty close to a schematic definition is nice.

I apologize for my mistake, then. My understanding was based on reading the Prometheus docs on making exporters alone - something I needed urgently for a job.

no apology needed, I am sorry the world has a culture of mistakes being a bad thing.
