## TL;DR
Prometheus is a monitoring system centered on time-series metrics, labels, PromQL, and alerting rules. Evidence should come from its documentation.

## Core Explanation
Prometheus scrapes or receives metrics, stores them as labeled time series, and evaluates queries and alerting rules over those series.

## Detailed Analysis
The repaired article cites Prometheus overview, data model, and alerting-rule documentation.
