Tracing
Every answer leaves
a paper trail.
Each request becomes an OpenTelemetry trace — auth, retrieval, tool calls, model, tokens, latency and cost. Nothing about a reply stays a mystery.

Inside one request
Read a request span by span. In the order it ran.
A trace is not a log line. It is the sequence of steps the agent actually took, each with a duration you can compare against the others.
Auth
Which key, which user, which scope — and the milliseconds spent checking all three.
Retrieval
The documents and FAQs that were pulled, their similarity scores, and the page each passage came from.
Tool calls
Every MCP call with its arguments, its response and its latency. The one that timed out is obvious.
Model
Prompt tokens, completion tokens, time spent streaming and the cost of the call. Per request, not per month.
Across all of them
Find the slow one. Then fix the cause.
Narrow thousands of requests down to the handful worth reading, attribute the spend, and take the spans wherever your team already looks.
Query the history
Filter by agent, user, status or latency. “Everything over two seconds yesterday” is one query, not an afternoon.
Cost per agent
Token spend split by agent and by day, so the bill arrives with a name already attached to it.
Token spend · this month
Grouped failures
Errors cluster by type and by tool, so you repair the integration that is actually breaking rather than the loudest one.
Export the spans
OpenTelemetry out to the APM or warehouse you already run. Your traces, your retention, your dashboards.
What teams say
“Every time you want to add AI to your app, you end up writing a ton of code — managing API keys, handling conversation history, engineering prompts, counting tokens. And then six months later a better model comes out and you have to refactor everything. SentientOne just removes all of that.”
