fastiot_core_services.nats_logger package

Minimal module to read out nats messages

This module is intended for debugging purposes and not for longer production runs.

Per default this module tries to read out and print all data recursively under v1.. You may adjust this and also add some filters using environment variables defined in fastiot_core_services.nats_logger.env.NatsLoggerConstants.

If not using a docker-compose file generated with your project you also have to set variables for broker and port FASTIOT_NATS_HOST and FASTIOT_NATS_PORT.

For debugging you may run the container solo using the docker command like this

docker run -e FASTIOT_NATS_BROKER_HOST="10.62.12.25" -e FASTIOT_NATS_BROKER_PORT="4222" \
  -e FASTIOT_NATS_LOGGER_SUBJECT="v1.thing.my_sensor" \
  -e FASTIOT_NATS_LOGGER_FILTER_FIELD="value" \
  -e FASTIOT_NATS_LOGGER_FILTER_VALUE="5" \
  docker.dev.ivv-dd.fhg.de/fastiot/nats_logger

If you want to run the container locally and connect to your local nats container you have to specify the network manually.

  1. First list your local docker networks with docker network ls

  2. Start docker with docker run --network your_local_FASTIOT-net -e FASTIOT_NATS_BROKER_HOST="nats"  …
