Event Hub Consumer Telegraf Plugin
Azure Event Hub and Azure IoT Hub are both fully managed services from Microsoft that support communication between devices and the cloud. Azure Event Hub is a data streaming and event ingestion platform that receives and processes event data. Azure IoT Hub is a central message hub for bidirectional communication between IoT applications and devices. These hubs are secure and scalable and ingest data in real time.

Some use cases this supports include managing industrial equipment in manufacturing, tracking assets in healthcare, and monitoring energy consumption of traffic congestion in smart city solutions.
How to use the Event Hub Consumer Telegraf Plugin
To use this plugin you first need to sign up for an account with Azure Event Hub or Azure IoT Hub. Then you need to create a device such as a simulated Raspberry Pi. The connection string needed for the plugin is located under “Shared access policies” and both the “iothubowner” and “service” policies should work.
