Tracing AI Agent Execution Paths and Costs with NVIDIA NeMo Relay and Phoenix
NVIDIA Developer · youtube · 2026-10-01
NVIDIA Developer published a tutorial on capturing a Hermes Agent's full execution path with NeMo Relay, from the initial request and file-reading tool calls to the final answer.
- The trace covers which tools the agent used, what data it accessed, tokens consumed, and the cost of the run
- The video opens the trace in Phoenix to review sessions, model and tool activity, and redacted data
- NeMo Relay records activity locally while a sanitizer strips PII before the trace leaves the machine
- Companion resources include GitHub examples (NeMo-Relay, nemoclaw-community) and a tech blog, useful for debugging, evaluation, and agent reliability work
