Layer A — Model & request health
Latency, errors, cost, and provider availability. Tools like Helicone, Langfuse, or cloud monitors often start here.
Model and request metrics matter — production agent fleets also need behaviour signals, anomalies, and Runtime Cases when tools and intent fail.
LLM Monitoring typically tracks generations, latency, token cost, error rates, and sometimes prompt/version quality. That is necessary. It is not sufficient when multi-step agents choose the wrong tool with a successful HTTP 200 from the model provider.
Latency, errors, cost, and provider availability. Tools like Helicone, Langfuse, or cloud monitors often start here.
Scores, eval datasets, prompt experiments — Braintrust, LangSmith, Arize/Phoenix-style loops improve outputs before and after ship.
Sessions, decisions, tool selection, policy gaps, and recovery. PUVINoise specializes here as Behaviour Runtime Intelligence.
Runtime Cases, MTTR, audit trails, and human override so monitoring closes into trusted remediation — not only dashboards.
Langfuse, LangSmith, Helicone, and similar tools remain valuable for prompt and request visibility.
vs Langfuse →Braintrust and eval harnesses strengthen quality loops; production still needs behaviour ops.
vs Braintrust →PUVINoise for Command Centre, anomalies, Runtime Cases, and governed recovery across tenants.
Product overview →Usually no. Those tools excel at LLM tracing or gateway analytics. PUVINoise adds behaviour runtime and recovery for agent fleets. See Compare for fair framing.
LLM Monitoring emphasizes model/request quality. Agent Observability emphasizes multi-step agent operations and MTTR. Read both guides — they reinforce each other.
