Monitoring greedy containers (Part 1)

Luca Marturana's blog post discusses the complexities of monitoring resource allocation in containerized environments, specifically focusing on the challenge of "greedy" containers that consume more resources than allocated, which can impact performance and cost efficiency. The post introduces the importance of understanding container resource consumption on a per-service basis, rather than overall VM utilization, especially as orchestrated containers become more prevalent. Marturana explains the use of Cgroups in container resource allocation, covering parameters like memory limits, CPU shares, and CPU quotas, and demonstrates how tools like Sysdig Cloud can help visualize and manage these allocations effectively. By using metrics such as memory.limit.used.percent and cpu.shares.used.percent, users can set alerts and make informed decisions to optimize resource use. The post concludes by emphasizing the necessity of monitoring container resource usage for optimal performance and hints at a follow-up post that will explore practical examples of managing resource contention in orchestrated environments.
