Posted on February 27, 2023, Level intermediate Resource Length short

How Grafana Labs uses and contributes to OpenCost, open source project for real-time cost monitoring in Kubernetes
Posted on February 10, 2023, Level beginner Resource Length medium
While more and more teams are adopting Kubernetes as their standard container orchestration technology, cost insight is lacking. Teams often don't know how much they're spending, where in their organization they are spending, or what is driving their infrastructure cost increases. OpenCost helps alleviate this problem by bringing real-time cost monitoring to Kubernetes workloads with a solution that encompasses both an open specification and an open source project.

This is achieved by writing events into per-P buffers, using RDTSC for timestamps, and encoding into a relatively efficient binary format. By Felix Geisendörfer.
