Prometheus is an open-source resource connected to infrastructure, metrics, and observability. In the OT archive, this entry is tagged as: infrastructure, metrics, observability, open-source — a shorthand for the kinds of practice and politics it connects to. Beyond the headline: Prometheus is included here because it helps imagine technology as something collective — built, maintained, and argued about in public — rather than only as a private product. If you follow the link, you will usually find primary documentation, community governance, or ongoing work that is hard to summarize in a single paragraph. Treat this page as a bookmark and a doorway, not a replacement for reading the source.
