This document discusses monitoring and managing containers using open source tools. It outlines challenges with distributed container architectures and metrics for measuring container performance. Tools covered for monitoring and managing containers include Cadvisor, Sysdig, and Portainer. Rancher is presented as a platform for administering Kubernetes clusters. The document concludes that these tools help detect issues, safely upgrade systems, and refine applications for better performance and robustness.
