Google Confidential and Proprietary Why cAdvisor? ● Resource isolation on a multi-tenant system is difficult ● To understand resource utilization and performance of containers today, one needs to: ○ Understand various (complicated) Linux APIs ○ Understand different container solutions 

Google Confidential and Proprietary What is cAdvisor? ● aka ‘Container Advisor’. Built for containers. ● Give users an understanding of container resource usage and performance ● Simple, lightweight, standalone, open source ● Supports Docker containers natively! ● Written entirely in Go!
