Prometheus query to calculate a ratio between two series
You want usage / limit, not limit / usage You want the average CPU seconds rate over a small window to see granular changes over the time range, not the average over that large grafana range variable. So change it to [1m] or [5m]. You might want to try irate which calculates the rate over the last two days points in the window rather than the average. More on reddit.com

Prometheus 2: An Open Source Language Model that Closely Mirrors Human and GPT-4 Judgements in Evaluating Other Language Models
The research team from KAIST AI, LG AI Research, Carnegie Mellon University, MIT, Allen Institute for AI, and the University of Illinois Chicago introduced Prometheus 2, a novel open-source evaluator designed to assess language models to resolve it. This model was developed to provide transparent, scalable, and controllable assessments while matching the evaluation quality of proprietary models. Prometheus 2 was developed by merging two evaluator LMs: one trained exclusively for direct assessment and another for pairwise ranking. The merging of these models created a unified evaluator that excels in both evaluation formats. The researchers utilized the newly developed Preference Collection dataset, which features 1,000 evaluation criteria, to refine the model’s capabilities further. By effectively combining the two training formats, Prometheus 2 can evaluate LM responses using direct assessment and pairwise ranking methods. The merged model leverages a linear merging approach to blend the strengths of both evaluation formats, achieving high performance across evaluation tasks.

What are the types of Prometheus metrics
Prometheus metrics are categorized into four types: Counter, Gauge, Histogram, and Summary. Each type serves a different purpose in monitoring and alerting

How does Prometheus store data
Prometheus stores data in a time series database. Each metric is identified by a unique name and associated labels, and the data is stored with timestamps

What are the different formats in which Prometheus presents data
Prometheus presents data in four formats: String, Scalar, Instant Vector, and Range Vector. String is a text format, Scalar is a numerical value, Instant Vector provides a single value per series, and Range Vector gives a set of values over a time range
