Azure IoT

This forum is to get feedback on the new IoT services: Azure IoT Hub and Azure IoT suite. This forum will help the engineering team collect feedback from our customers and users and help us understand and prioritize the roadmap.

  1. Get an alert when reaching the max quota of the IoT Hub

    Hi,

    Sometimes we send more messages than the size of the IoT Hub allows. We'd like to be able to receive an alert when this scenario occurs.

    The current Alert system for IoT Hub allows to setup a dynamic threshold to any metrics but there is not option to limit the quota.

    Thank you.

  2. Add metrics related to messages process status under traffic shaping

    Hi,

    From Azure documentation: "To accommodate burst traffic, IoT Hub accepts requests above the throttle for a limited time. The first few of these requests are processed immediately. However, if the number of requests continues violate the throttle, IoT Hub starts placing the requests in a queue and processed at the limit rate."
    https://docs.microsoft.com/en-us/azure/iot-hub/iot-hub-devguide-quotas-throttling

    In these circumstances, some messages are not sent immediately.
    In order to know what is happening to our messages, we would like to get the following metrics:
    - The number of messages not sent because of the IoT Hub size limit
    - The number of messages…

  3. I'm trying to run an Azure IoT intro class at Collin College in Texas. Need Microsoft help

    I purchased two official Adafruit feather HUZZAH Azure IoT Starter Kits. The IoT Hub creation script has been changed. Where can I find the current script?

    Also, do you have an academic program? Why can't I choose F! subscriptions for my class? Do you have a working script for my project kit or any other kit?

  7. RFC 6066 max fragment length

    Please support the RFC 6066 standard for negotiating max. fragment lengths. I have now encountered a lot of scenarios where IoT devices receive too large packets.
    This has already been mentioned in 2018 here: https://social.msdn.microsoft.com/Forums/en-US/4d4fbaee-01c3-4d51-9c91-ad048f852103/tlsssl-fragmentation?forum=azureiothub

  8. IoT Hub keep insight after quota expiration

    ::this is feedback that was originally logged on the IoT Edge UserVoice forum; however it belongs in the IoT Hub forum::

    After your daily quota has expired you lose insight into your device list and cannot take any action without physical/ssh access to it. However for an IoT use-case neither physical, nor ssh access to all of your devices is given.

    The solution would be, not to count administrative messages (like reading the device list and disabling a babbling device) towards the message quota.

    Since Microsoft wants to make money, maybe an option like "either all messages are counted towards…

  9. IOT Streaming Data using Azure Synapse Analytics

    hi we have azure subscription and i am trying to propose Azure Synapse Analytics to my team. We are currently having a lot of IOT data which is semi-structured/structured data and i want to understand how Azure Synapse Analytics can help with IOT Streaming data. The IOT data is coming from various sources example SAP etc in the form of csv files to Azure Blob Storage. how can i move this data over to Synapse Analytics. how would my architecture look like. how should i design my pipelines. What query method should i use. Polybase vs BCP. Can you please…

  10. Integration of LogicApps Triggers with the IoTHub are not working correctly

    The IoTHubs Events of LogicApps are not working correctly. As far as I can tell, a LogicApps application is only executed when one chooses all IoTHubs Event Types:
    -Microsoft.Devices.DeviceCreated
    -Microsoft.Devices.DeviceDeleted
    -Microsoft.Devices.DeviceTelemetry
    -Microsoft.Devices.DeviceConnected
    -Microsoft.Devices.DeviceDisconnected
    Selecting only a subset of these 5 will result in the LogicApps application to never execute even when the event has happened.

    For example: Selecting
    -Microsoft.Devices.DeviceCreated
    -Microsoft.Devices.DeviceDeleted
    -Microsoft.Devices.DeviceTelemetry
    -Microsoft.Devices.DeviceConnected
    -Microsoft.Devices.DeviceDisconnected
    as Event Types to trigger the LogicApps application and creating/deleting devices via the IoTHub UI will result in no Trigger. Only when one adds the last Event Type will the LogicApps application be triggered.

  11. fine grained access control for IoT device streams

    I would like to allow users to SSH to devices using the forthcoming azure iot device streams feature, but I don't want these users to have access to the full serviceconnect token permissions such as editing the device twin. add a way to limit the token I give to device streams users. see this github thread

  12. Add system property SessionId to the Message

    Add a new system property SessionId to the Message (Microsoft.Azure.Devices.Client) to enable usage of
    https://docs.microsoft.com/en-us/azure/service-bus-messaging/message-sessions in case of following path of messages: device -> IoT Hub -> Service Bus Topic -> Azure Function

    Service bus demands system property, but does not take into account custom properties.

    Without such support it is almost impossible (or demands additional effords and resources) to implement sequential messages processing using Service bus

    Discussions of this problem:

  13. Configure Properties on IotHub doesn't work

    I ran the following command
    az iot hub update --name {your iot hub name} \
    --set properties.storageEndpoints.'$default'.connectionString="{your storage account connection string}" in a bash script and I receive

    Couldn't find '$default' in 'properties.storageEndpoints'. Available
    options: []

    I just followed the steps provided https://docs.microsoft.com/en-us/azure/iot-hub/iot-hub-configure-file-upload-cli to enabled file uploading for my iotHub instance.

  14. Log the IPs of the devices that invoke the direct methods

    I would like a way on Azure Portal to display the IPs of the devices that have invoked a Direct Methods (not those that execute them) on my IoTdevices and the date and time of the event. Alternatively a way to identify these callers

  17. IoT Hub DeviceTwins to store device public ip address

    If the default metadata of the DeviceTwins document could store LastKnownPublicIPAddress value, that would help some customers to further do maintenance on their devices.

    This request came from one of our customers.

  18. Enable per device message throttling capability

    From the cost and cyber security perspective, its ideal to set message throttling/quote per device instead of at the IoTHub Level. there is a possibility that one rogue device eating the complete limit of one or more IoTHubs if we cant throttle per device.

  19. IOT Hub and Device Prov. Service Security

    Hi Team,

    current documentaiton does not provide much details about how to secure IOT HUB/Device provisioning service by adding api layer (NGINX) on top of core paas services.

    Is device connecting using X.509 CA certificates to IOT HUB/DPS is enough secure? do we need to add extra gateway layer on top of these PAAS services?

    Thanks

  20. Is Metrics/Diagnostics under IOT Hub to view Device telemetries or it is for IOT Hub health monitoring?

    Hi team, bit confused with the documentation about metrics and diagnostic logs.

    is metrics and diagnostic logs feature under IOT Hub is to view the messages sent by devices connected to that hub AND/OR this feature is only to view the logs of IOT hub performances and failures?

    what is the recommended PAAS application to view the messages/logs sent by devices? I don't want to build new application or use power BI tool. looking for something within Azure itself which lets me view the messages sent by devices more interactively (filer/report etc...)

    Thanks
    Bhupal
