A session groups the traces that belong to one conversation or user interaction, across workflows and agents. Set a sessionId on your calls, typically a chat or thread id, and Foglamp groups every turn under it.
Only traces with a sessionId appear here. If you don’t set one, the call is still recorded under Traces; it just isn’t grouped into a session.

Sessions list

A paginated table over the selected range: session id, the agent involved, turn count, tokens, cost, and last activity. Sessions with errors carry a badge.

Session detail

Opening a session shows stat cards (turns, tokens, duration, cost) and a conversation timeline, one block per turn, in order. Each turn shows:
  • the user message, with a control to view the full raw input if it was cut off,
  • the assistant’s output for that turn,
  • the turn’s cost, tokens, and duration,
  • a link to the underlying trace, plus workflow and error badges where relevant.
A session reads like the conversation it represents, and the full execution detail of any turn is one click away.
