「Slothは、私たちがYAMLでSLI/SLOを定義するだけで、SLI計測に必要なPromQLやPrometheusのルールを自動生成してくれます」ほう
Grafana,Prometheus,Slothで実現するSLI/SLO管理入門：Slothの裏側を探るPromQL解読ガイド [DeNA インフラ SRE] | BLOG - DeNA Engineering
はじめに
サービスの信頼性を定量的に評価し、管理するためのSLI/SLO。その実現方法には、高機能なSaaS製品を利用する方法もあれば、PrometheusやGrafanaといったオープンソースソフトウェア（OSS）を組み合わせて構築する方法もあります。特に、コスト面の制約や、既にGrafanaなどの監視基盤が稼働している環境では、後者を選択するケースも少なくありません。

I finally got back to making a big new @prometheusio.bsky.social video with tons of explainer animations:
All about PromQL data selection!
* Instant/range vector selectors
* Label matchers
* Lookback delta
* Staleness handling
* Offsets
* "@" timestamps

メトリクス、ログ、トレースを一箇所で管理できるデータベースらしい。SQLとかPromQLでクエリもできるから、Observabilityデータの分析が楽になるかも。

I have no sane way to decompose those queries into smaller bits (e.g. I have value A divided by value B - in PromQL you write one big query, but in Grafana ideally I'd love to paint them seeparately) and share them across stacks.
How come a library to handle this does not exist yet?

really struggling to determine the set of metrics and calculations in promql to make windows' memory readouts in grafana useful. i get the math, what i don't get is which stats i actually need to care about

And regarding the metric name changes: yeah you can configure that easily, but the point is that no matter how you configure it, you end up with an unideal situation:
- Ugly quoted PromQL selectors when leaving names unchanged
- Different names in Prometheus when changing them
- Ugly quoted PromQL selectors when leaving names unchanged
- Different names in Prometheus when changing them
