Observability

AI Observability Becomes Essential for Generated Code and Agents

AI systems now write substantial portions of production code. Platform operators see a growing distance between what their existing monitors capture and what these systems do once running. The gap appears in higher incident volumes and extra time spent by engineers on fixes that trace back to model assisted changes.

Geth Adds Code Cache Hit Miss Meters for Live Operator Visibility

Ethereum’s main execution client just landed a small but practical change. Code cache hit and miss meters now ship as first class Prometheus signals, so operators no longer have to dig through slow block JSON dumps. The kind of unglamorous engineering that compounds across the network.
