The Cumulocity Dynamic Mapper addresses the need to get any data provided by a message broker mapped to the Cumulocity IoT Domain model in a zero-code approach. It can connect to multiple message brokers likes MQTT, MQTT Service , Kafka and others, subscribes to specific topics and maps the data in a graphical editor to the domain model of Cumulocity.

In the resource section you find a test profil jmeter_test_01.jmx using the performance tool jmeter
and an extension for MQTT: emqx/mqtt-jmeter.
This was used to run simple loadtest.
A script to create sample mappings can be found here. You have to start it as follows:
#python3 resources/script/mapping/import_mappings_01.py -p <YOUR_PASSWORD> -U <YOUR_TENANT> -u <YOUR_USER> -f resources/script/mapping/sampleMapping/sampleMappings_02.json
The mappings with inputs and substitutions are explained in the sample document.
