Session Trace and Flow Detail show much the same data from two angles.
Sessions
Your past conversations, from Orchestrator or direct Chat. Each row shows:- The agent’s name and initial avatar, or Orchestrator if no single agent handled it
- A message count and a preview of the last message
- Time since last active, grouped under Today, Yesterday, This Week, Older
Session trace
Every span behind a single query, in order, including nested agent-to-agent calls. The stats row shows Spans, Duration, Tokens (input + output), Cost when available, and the Session ID. The span list is indented to show nesting. Each span shows its name, model for LLM calls, token count, and duration; a red dot marks an error. Click a span for its kind, span ID, status, start and end times, model, and input/output token split.Traces take a few seconds to index. Opening one immediately after a conversation may say it isn’t available yet — refresh.
Flows
Every multi-agent interaction, as a searchable sortable table:
Search filters by agent name or query text.
Flow detail
Summary cards for Status, Root Agent, Duration, Started, Steps, and Query, then a Trace timeline. Each step shows:- A status badge
- The agent it called, with a preview of what was sent (hover for the full text)
- A bar sized and positioned to show when it ran relative to the whole flow — the slow hop is visible at a glance
- Its duration
Designing a fixed multi-step sequence rather than reviewing one that ran? See multi-agent workflows.
Tokens and cost
Token spend has its own screen — see TokenOps for per-agent cost, operations, agent hours, and latency by month, with CSV export. Cost also appears inline: a session trace’s stats row shows that query’s token count and dollar cost, so you can attribute one expensive answer without leaving the trace.API
Everything these screens show is available under/api/observability/*:
Configuration
Agents are traced with no code changes — every deployment gets OpenTelemetry configuration injected into its spec, so instrumentation starts at boot andtraceparent propagates across agent-to-agent hops automatically. If you run your own control plane, these are the knobs:
