Recording

Recording captures MQTT messages into local storage so a session can be inspected or replayed later.

What A Recording Captures

• topic
• payload
• quality of service
• retain flag
• received timestamp
• session identity

Typical Use

1. Connect to a broker.
2. Select the topics to observe.
3. Start a recording session.
4. Reproduce the system behavior you want to analyze.
5. Stop recording and name the session.

Notes

Recordings are local-first. This keeps debugging data available without requiring a hosted backend.

Flow Shape

MQTT connection resource
  -> MQTT trigger
  -> Optional topic filter
  -> Recording sink

The recording sink stores each incoming message for the selected recording session. If storing one message fails, the failure is reported as a flow error and later messages can continue recording.
