Observability for LLM Apps and Agents: OpenLIT SDK + VictoriaMetrics observability stack
Many “LLM observability with OpenTelemetry” tutorials stop at a single chat.completions span. That works for a demo, but it leaves gaps once an agent fans out into 30 tool calls, two vector-DB queries, three handoffs, and a 90-second tail latency you need to attribute.
