Observability expert Charity Majors and engineer Malte Ubl advocate for distinct alerting strategies for live LLM features, differentiating between silent failures like model drift and instruction adherence issues. They propose using trace-backed alerts for complex agentic systems and validator-based alerts for simpler completions. Key metrics to monitor include input/output distributions, human feedback, model variant performance, latency, and cost, all tied to trace IDs for effective debugging. AI
