description PLG Stack Overview

The PLG Stack is an open-source observability solution that combines Prometheus, Loki, and Grafana for monitoring metrics and logs within cloud-native environments. Grafana serves as the visualization layer, displaying time-series data collected by Prometheus and log data aggregated by Loki. This combination is popular among DevOps teams because it provides a highly scalable, interoperable, and unified dashboard for tracking the health and performance of modern infrastructure.
