When implementing a microservice-based architecture on top of Kubernetes it is always hard to find an ideal alerting strategy, specifically one that ensures reliability during day 2 operations. Despite growing our infrastructure a lot, adding tons of new products and learning some hard lessons about operating Prometheus at scale, our original architecture of Prometheus (see Monitoring Cloudflare's Planet-Scale Edge Network with Prometheus for an in depth walk through) remains virtually unchanged, proving that Prometheus is a solid foundation for building observability into your services. The flow between containers when an email is generated. Its a test Prometheus instance, and we forgot to collect any metrics from it.
