Real-time monitoring of agent traffic captures messages, events, and internal LLM calls using a pluggable monitor API with three independent buffers. It records per-agent activity and sends UI notifications via OnMessageRecorded, OnEventRecorded, and OnLlmCallRecorded.

Debugging and auditing per-agent activity works across development and production scenarios by recording messages, events, and LLM calls. An in-memory default buffer centralizes visibility into agent traffic for querying recent activity.

Optional payload capture with redaction for privacy allows recording agent messages without exposing sensitive data. The in-memory monitor supports configurable payload capture to balance debugging visibility with privacy requirements.

Real-time UI notifications for event streams are supported through OnMessageRecorded, OnEventRecorded, and OnLlmCallRecorded callbacks. These notify UI components immediately as new agent traffic is captured in the buffers.

Token tracking from LLM calls is handled by a dedicated buffer that records internal LLM calls independently from messages and events. This allows monitoring and auditing per-agent LLM usage and token consumption.

The in-memory default buffer stores recent agent traffic in memory, limiting historical retention to available memory capacity. For persistent auditing, reference captures via a references directory can supplement the in-memory monitoring.
