    The policies describes the rights allowed for a MS Azure account on a specific object (here an EventHub sream). The connection string contains the policy and the targeted EventHub information to allow an application to send messages to an eventHub.

    The next steps describe how to generate this connection string.

    Configuration Process

    Step 1. Create an Azure EventHub stream in the customer’s Azure account, into which AirVantage will publish:

    • In the left menu, click on > and filter with Event Hub
    • Click on Event Hub
    • Click on Add in the Event Hub management page to add a namespace
    • Fill each field as your convenience and click on Create

    Step 2. Create your Eventhub:

    • In the menu, select EventHubs
    • Click on +Event Hub in the top
    • Fill the name and change parameter at your convenience
    • Click on Create

    Step 3. Create a policy in the customer’s Azure account:

    • Select your eventHub
    • Click on Shared access policies
    • Click on Add to add a new policy for AirVantage
    • Fill each field. Enable Send (mandatory) and give it a name

    Step 4. Supply the following information using the CRM and select Request Support:

    • Connection string-primary key
    • Kind of messages you want to receive:
      • Alert event: any alert rule triggered will be send
      • Operation: any operation state will be sent (creation, progress, success or failed)
      • Usages: any SIM usage
      • New message sent by the device: any device incoming communication
        • Optionnaly you can supply the data path to whitelist the data (only the values for these data will be sent in the data stream). To get the data path for a data, you can go to the timeline to view the data path in the tooltip like in the screenshot below:

    Test your setup

    You can check that the data received from AirVantage shows up in the stream monitoring provided by Microsoft. The graph that describes the number of incoming request lets you ensure that AirVantage is connected to your EventHub stream. If no data is shown, you need to check your configuration.

    You can reach this graph in your EventHub’s verview section by scrolling to the bottom.

    Get the messages

    This section explains how to consume the messages from EventHub in order to support high volume messaging.

    EventHub is limited to event lesser than 256k (see this page , section Batch event send operations). So you may avoid to push over-sized data.

    Other limitations can be applied according to the selected offer (see Event Hubs Pricing page).
