Microsoft Azure IOT Hub API poller template
Use this template to monitor Microsoft Azure Event Hubs performance and statistics counters, including requests, messages, errors, connections and traffic.
- Values are provided for the following parameters:
- OAuth 2.0 Azure credentials are configured. See API poller authorization and authentication.
- Default thresholds are not set for this template.
- Here is an API request example:
- For reference, see Microsoft.Devices/IotHubs (© 2020, Microsoft Corp., available at docs.microsoft.com, obtained on March 22, 2020).
- You can add the following metrics:
Telemetry message send attempts (total)
The number of device-to-cloud telemetry messages attempted to be sent to your IoT hub.
Telemetry messages sent (total)
The number of device-to-cloud telemetry messages sent successfully to your IoT hub.
C2D message deliveries completed (total)
The number of cloud-to-device message deliveries completed successfully by the device.
C2D messages abandoned (total)
The number of cloud-to-device messages abandoned by the device.
C2D messages rejected (total)
The number of cloud-to-device messages rejected by the device.
Routing: telemetry messages dropped (total)
The number of times messages were dropped by IoT Hub routing due to dead endpoints. This value does not count messages delivered to fallback route as dropped messages are not delivered there.
Routing: messages delivered to fallback (total)
The number of times IoT Hub routing delivered messages to the endpoint associated with the fallback route.
Routing: message latency for Event Hub (avg)
The average latency, in milliseconds (ms), between message ingress to IoT Hub and message ingress into an Event Hub endpoint.
Routing: message latency for Service Bus Queue (avg)
The average latency between message ingress to IoT Hub and telemetry message ingress into a Service Bus queue endpoint.
Routing: message latency for Service Bus Topic (avg)
The average latency between message ingress to IoT Hub and telemetry message ingress into a Service Bus topic endpoint.
Routing: message latency for messages/events (avg)
The average latency between message ingress to IoT Hub and telemetry message ingress into the built-in endpoint (messages/events).
Routing: message latency for storage (avg)
The average latency between message ingress to IoT Hub and telemetry message ingress into a storage endpoint.
Failed twin reads from devices (total)
The count of all failed device-initiated twin reads.
Failed twin updates from devices (total)
The count of all failed device-initiated twin updates.
Failed direct method invocations (total)
The count of all failed direct method calls.
Failed twin reads from back end (total)
The count of all failed back-end-initiated twin reads.
Failed twin updates from back end (total)
The count of all failed back-end-initiated twin updates.
Total device data usage (total)
Bytes transferred to and from any devices connected to Iot Hub.
Total devices (avg)
Number of devices registered to your IoT hub.
Connected devices (avg).
Number of devices connected to your IoT hub.
