An opinionated roadmap to become an SRE

This two-article series is about monitoring. Part One covers accumulating a multitude of different metrics in a single place, handling permissions for different aspects of those metrics, and storing large amounts of data. In Part Two, we then focus on choosing monitoring systems based on the brief example of a fictional company’s “journey” in struggling with continually expanding its monitoring system and growing its infrastructure.

In this post, we are going to dive a bit deeper into CPU and share some general recommendations for specifying CPU requests and limits. We will also explore the differences between using the default policy (CFS quota) and the CPU Manager’s static policy. We are not going to consider memory resources in this post.
