$ Prometheus

This page gathers the essential facts about Prometheus in one place: what the project does, how its command-line interface is organised, and where the maintainers publish their own setup instructions.

Quick reference

How to read the official docs

• Official project pages. The maintainers' own site is the only source that stays current. We link to it and summarise; we never rehost.
• Purpose and scope. What problem the tool solves and where its responsibilities end — taken from the project's own description.
• Interface shape. How the command is invoked, which subcommands exist, and what the essential flags do.
• Setup pointers. Where the canonical step-by-step instructions live, platform by platform, on the official pages.

Suggested first pass

• Read the official setup notes end to end once before typing anything, so later steps make sense in context.
• Note which configuration files or environment variables the tool reads; this is documented on the project site.

When you are ready, follow the project's own instructions from its official page — that is the version the maintainers test and keep correct. This note exists so you can find your bearings before you start.
