Session record count

​

Definition

​

Taxonomy

• Task types: LLM.
• Availability: development and monitoring.
• Evaluation level: session.
• Computation: deterministic aggregation.

​

Why it matters

• Runaway sessions (too many turns) often signal tool-call loops, clarification loops, or frustrated users hammering on the same question.
• Very short sessions (one turn then drop-off) may signal users bouncing off the product before the assistant could help.
• Track both tails — mean and percentile views of session length often tell very different stories.

​

Available measurements

​

Required columns

• Session ID: Groups turns belonging to the same conversation.
