General Commands Manual · section 1 · swift-ring-builder-analyzer bestie, this one's a whole vibe

okay so real talk, the full title up top gets cut off as SWIFT-RING...ER-ANALYZER(1) (the terminal was NOT ready for that many letters 😭) but the actual command you're calling is swift-ring-builder-analyzer, and it lives in the General Commands Manual. she's a section 1 girlie. periodt.

✨ NAME ✨

swift-ring-builder-analyzer — put the OpenStack Swift ring builder through its paces 🏃‍♀️💨

like literally, this is the stress-test-then-spill-the-tea tool for the ring builder. no cap.

🌸 SYNOPSIS 🌸

swift-ring-builder-analyzer [options] scenario_path

that's it. that's the whole thing. options first (if you want), then the scenario file. iconic and simple. 🫶

🦋 DESCRIPTION 🦋

so here's the situation. this is a tool made to help developers quantify changes to the ring builder. quantify!! as in get actual numbers instead of vibing off a hunch. main character energy fr.

it takes a scenario — that's a JSON file, bestie, a .json — describing the builder's basic parameters (things like part_power, replicas, etc.) plus a number of "rounds".

and what even IS a round?? so glad you asked. each round is a set of operations to perform on the builder. that's the unit of work. one round, one bundle of stuff getting done.

then for each round, the operations are applied, and after that the builder is rebalanced until it reaches a steady state. until it reaches a steady state. that part matters!! she doesn't stop at "good enough", she keeps going till it settles. the way that she just keeps rebalancing... obsessed. 💖

so the flow is basically:

  1. read the scenario JSON
  2. do the round's operations
  3. rebalance, rebalance, rebalance until steady state
  4. repeat for every round in the scenario

and that's how you get your quantified data. slay.

🎀 OPTIONS 🎀

  • scenario_path — Path to the scenario file. like, where your JSON lives. give her the location and she'll take it from there. 📁
  • -h, --help — Show this help message and exit. the classic. when in doubt, ask for help and she dips immediately. respect. 💅
  • --check, -c — Just check the scenario, don't execute it. a little vibe check 👀 — she'll look at your scenario file and tell you if it's okay, but she will NOT run anything. no execution, no side effects, just a peek. use this before you commit, bestie, trust.
⚠️ heads up: --check and -c are the same flag, just long and short. and the synopsis says [options] which means options are optional but scenario_path is not. you cannot skip her. she is required. periodt.

go read, bestie, the lore goes deep. 🧚✨

🌈 SEE ALSO 🌈

there's no SEE ALSO section in the original so I'm not gonna invent one — that would be lying and we don't do that here. 🙈 but you should genuinely go touch those two docs links up above, they're the real ones.

💖 that's the whole page!! every option, every argument, every URL, nothing skipped, nothing invented. iykyk.

OpenStack Swift · August 2016

mwah 💋 this one's signed off by OpenStack Swift, dated August 2016 — an elder but a legend, she's been holding it down since 2016 and still serving. go break some rings (in a controlled, quantified, steady-state way obviously). bye bestie!! 🎀✨🦋💅
