Device Simulator block

Inbound Device Message block

Outbound Device Message block

This block sends messages to device connectivity services such as the MQTT service. The block takes the message payload as a base64-encoded string. It requires a Streaming Analytics microservice of at least version 26.263.0.

Create External Measurement block

This block allows creation of measurements using external device IDs rather than internal Managed Object IDs, and can automatically create devices for missing external IDs.

Adding custom blocks as extensions

To use these blocks you should install the Analytics Management plug-in to your Cumulocity environment, and then link it to this repository using the https://github.com/mjj29/c8y-analytics-blocks/tree/main/blocks/ directory.

This will allow you to select from the blocks in this repository

Running tests

To run tests you will need an Apama installation and a copy of the Apama Analytics Builder Block SDK. Source the apama_env from your Apama installation and export ANALYTICS_BUILDER_SDK=/location/of/apama-analytics-builder-block-sdk, then run pysys run in the tests/ directory of this repository.
