What the full piece covers

• ai agent observability: three questions, one record — An agent run does not look like a chat completion, and observability built for chat completions does not fit it.
• llmops: the agent run as the unit of analysis — LLMOps is the practice of running language-model systems as production software, and its centre of gravity shifts when the system is an agent.
• agent evaluation: read the trace before you trust the answer — Agent evaluation and agent observability are usually discussed as separate disciplines, and in practice they share one artifact: the trace.
• Where the run id comes from, read from our own implementation — A run view needs an identifier that both sides agree on.
• ai agent monitoring: latency budgets and failure modes — Monitoring an agent means watching the run's shape over time, not just its error rate, because an agent degrades before it fails.
• langfuse alternative: what an agent-run view adds to prompt tracing — If you already run prompt-level tracing, the honest question is not which dashboard is prettier but which events exist in the record.
• langsmith alternative: trace data and the privacy boundary — A trace is more sensitive than a log line, and that is the fact most observability rollouts discover late.
• How to get started — The first move is not a product; it is a correlation id and one row per step.
• Where SmartGate fits — SmartGate is the control plane an agent run passes through, made concrete: an MCP-native algorithm gateway for token control, traffic shaping and agent audit.
• Limitations — This page is a design frame for the agent layer, and it is deliberately bounded.
