Azure IoT Hub Deployment: Default eventHub endpoint 'operationsMonitoringEvents' is missing

Question

Recently I had issues to deploy an IoT Hub. I used an Azure Resource Manager (ARM) template that worked so far but then resulted in the error Default eventHub endpoint 'operationsMonitoringEvents' is missing. Below what you have to add to achieve a successfull deployment.

Answer 1

You need to add the eventHub endpoint 'operationsMonitoringEvents'

"operationsMonitoringEvents": {
    "retentionTimeInDays": "[parameters('opMonRetentionTimeInDays')]",
    "partitionCount": "[parameters('opMonPartitionCount')]",
    "path": "[concat(parameters('iotHubName'),'-operationmonitoring')]",
    "endpoint": "[parameters('opMonEndpoint')]"
}

The endpoint can be found e.g. via the portal here

Additionally you can configure operations monitoring e.g. via

"operationsMonitoringProperties": {
    "events": {
        "None": "None",
        "Connections": "None",
        "DeviceTelemetry": "None",
        "C2DCommands": "None",
        "DeviceIdentityOperations": "None",
        "FileUploadOperations": "None",
        "Routes": "None"
    }
}

Edit: as mentioned by Dipti Mamidala it is also enough to add only

"operationsMonitoringEvents": {
    "retentionTimeInDays": "[parameters('opMonRetentionTimeInDays')]",
    "partitionCount": "[parameters('opMonPartitionCount')]"
}
