Record And Replay

This workflow captures live MQTT traffic and replays it later.

Steps

1. Connect to the broker.
2. Subscribe to the target topics.
3. Start recording.
4. Exercise the system under test.
5. Stop recording.
6. Create a replay flow.
7. Replay the session into a selected broker or analysis view.

Replay Flow Shape

Recorded session
  -> Replay source
  -> Topic filter
  -> MQTT publish sink

Use a topic filter when the recording contains traffic that should not be replayed.

Recording Flow Shape

MQTT connection resource
  -> MQTT trigger
  -> Topic filter
  -> Recording sink

The recording sink writes MQTT messages into local storage for the active recording session.
