Introduction

Cloud Looking Glass (CLG) applies the three pillars of observability — metrics, logs, and traces — to enhance transparency around the health and performance of hyperscale cloud control planes. Serving as gatekeepers to cloud infrastructure, these systems are critical for auto-scaling, continuous deployment, and other automation processes used by modern cloud-based workloads. CLG enriches traditional (data plane) observability by adding actionable insights for these mission-critical systems.
