I am trying to send messages to google pubsub through Thingsboard using MQTT broker . I am using only one instance of Thingsboard and thingsboard is installed on kubernates. But there I am facing messages loss. Is single instance cause this problem or any thing else is there ?
Please have a look in the Thingsboard logfile, if there are any errors regarding data processing.
Also you could consult the API Usage Dashboard (Rule Engine --> View Statistics) if there are errors in rulechains.
You may also consider increasing the performance by changing the internal queue of Thingsboard to Kafka or Confluent Cloud (if not already used)
