Observe Traffic

Traffic observation turns live MQTT messages into operational counters.

Typical Flow

text

MQTT connection resource
  -> MQTT trigger
  -> Optional topic filter
  -> Metrics sink
  -> UI projection

Metrics

The metrics sink tracks:

total message count
total payload bytes
minimum payload size
maximum payload size
average payload size
retained message count
unique topic count
last observed topic

Notes

Metrics are a projection of live traffic. They do not store messages and do not change the messages flowing through other branches.

OpenTelemetry export is planned for a later version. Local metrics will continue to work without an external collector.
