Scaling Low-Overhead Instrumentation
Brian Martin describes the performance costs of metrics libraries and outlines techniques for keeping instrumentation lightweight at scale. He highlights atomic primitives, per-CPU sharding, lock-free histograms, and eBPF integration as ways to preserve observability without significantly affecting system performance.
