About Prometheus
Prometheus is an open source monitoring system and time series database, part of the Cloud Native Computing Foundation ecosystem. It collects metrics from configured targets at defined intervals, evaluates alerting rules, and visualizes results. Designed for reliability in dynamic environments, it operates without reliance on distributed storage, ensuring each server node functions independently.
