This conference talk explores the environmental impact of technology, particularly focusing on how to make OpenTelemetry Collectors more energy-efficient. Learn about the Kepler project, which exposes power consumption metrics from applications running in Kubernetes clusters. Discover how to deploy Kepler and see a demonstration of tweaking OpenTelemetry Collectors' power consumption in Kubernetes environments. Gain practical knowledge on deploying greener collectors to reduce both power consumption and operational costs. The presentation addresses the growing environmental concerns of data centers consuming 2% of global power and how observability tools, while necessary for understanding complex systems, contribute to the increasing global tech carbon footprint.
