Azure Resource Notifications - Resource Management events in Azure Event Grid

  • Article

The Azure Resource Management system topic provides insights into the life cycle of various Azure resources.

The Event Grid system topics for Azure subscriptions and Azure resource groups provide resource life cycle events using a broader range of event types including action, write, and delete events for scenarios involving success, failure, and cancellation. However, it's worth noting that they don't include the resource payload. For details about these events, see Event Grid system topic for Azure subscriptions and Event Grid system topic for Azure resource groups.

In contrast, the Azure Resource Notifications (ARN) powered Azure Resource Management system topic offers a more targeted selection of event types, specifically CreatedOrUpdated (corresponding to ResourceWriteSuccess in the Event Grid Azure subscription system topic), and Deleted (corresponding to ResourceDeleteSuccess in the Event Grid Azure subscription system topic). These events come with comprehensive payload information, making it easier for customers to apply filtering and refine their notification stream.

For the list of resource types exposed, see Azure Resource Graph resources or use the following Azure Resource Graph query.

resources
| distinct ['type']

Note

Azure Resource Management system topic doesn't yet support all the resource types from the resources table of Azure Resource Graph. We are working on improving this experience.

Event types

ARN Resources system topic offers two event types for consumption:

Event type Description
Microsoft.ResourceNotifications.Resources.CreatedOrUpdated Raised when a resource is successfully created or updated.
Microsoft.ResourceNotifications.Resources.Deleted Raised when a resource is deleted.

Role-based access control

Currently, these events are exclusively emitted at the Azure subscription scope. It implies that the entity creating the event subscription for this topic type receives notifications throughout this Azure subscription. For security reasons, it's imperative to restrict the ability to create event subscriptions on this topic to principals with read access over the entire Azure subscription. To access data via this system topic, in addition to the generic permissions required by Event Grid, the following Azure Resource Notifications specific permission is necessary: Microsoft.ResourceNotifications/systemTopics/subscribeToResources/action.

Event schemas

This section provides schemas for the CreatedOrUpdated and Deleted events.

Event schema for CreatedOrUpdated event

Here's the schema:

{
    "id": "string",
    "source": "string",
    "subject": "string",
    "data": {
        "resourceInfo": {
            "id": "string",
            "name": "string",
            "type": "string",
            "location": "string",
            "tags": "string",
            "properties": {
                "_comment": "object-unique-to-each-publisher"
            }
        },
        "apiVersion": "string",
        "operationalInfo": {
            "resourceEventTime": "datetime"
        }
    },
    "type": "string",
    "specversion": "string",
    "time": "string"
}

Event schema for Deleted event

Here's the schema:

{
    "id": "string",
    "source": "string",
    "subject": "string",
    "data": {
        "resourceInfo": {
            "id": "string",
            "name": "string",
            "type": "string"
        },
        "operationalInfo": {
            "resourceEventTime": "datetime"
        }
    },
    "type": "string",
    "specversion": "string",
    "time": "string"
}

An event in the Event Grid event schema format has the following top-level properties:

Property Type Description
id String Unique identifier of the event
topic String The Azure subscription for which this system topic is being created
subject String Publisher defined path to the base resource on which this event is emitted.
data Object Contains event data specific to the resource provider. For more information, see the next table.
eventType String Registered event type of this system topic type
dataVersion String The schema version of the data object
metadataVersion String The schema version of the event metadata
eventTime String
Format: 2022-11-07T18:43:09.2894075Z		 The time the event is generated based on the provider's UTC time

An event in the cloud event schema format has the following top-level properties:

Property Type Description
id String Unique identifier of the event
source String The Azure subscription for which this system topic is being created.
subject String Publisher defined path to the base resource on which this event is emitted.
type String Registered event type of this system topic type
time String
Format: 2022-11-07T18:43:09.2894075Z		 The time the event is generated based on the provider's UTC time
data Object Contains event data specific to the resource provider. For more information, see the next table.
specversion String CloudEvents schema specification version.

The data object has the following properties:

Property Type Description
resourceInfo Object Data specific to the resource. For more information, see the next table.
apiVersion String API version of the resource properties.
operationalInfo Object Details of operational information pertaining to the resource.

The resourceInfo object has the following common properties across CreatedOrUpdated and Deleted events:

Property Type Description
id String Publisher defined path to the event subject
name String This field indicates the Event-id. It always takes the value of the last section of the id field.
type String The type of event that is being emitted. In this context, it's either Microsoft.ResourceNotifications.Resources.CreatedOrUpdated or Microsoft.ResourceNotifications.Resources.Deleted.

The resourceInfo object for the CreatedOrUpdated event has the following extra properties:

Property Type Description
location String Location or region where the resource is located.
tags String Tags for the resource.
properties Object Payload of the resource.

Only the CreatedOrUpdated event includes the properties object. The schema of this properties object is unique to each publisher. To discover the schema, see the REST API documentation for the specific Azure resource. You can find an example in the Examples events section of this article.

            "properties": {
                "_comment": "<< object-unique-to-each-publisher >>"
            }

The operationalInfo object has the following properties:

Property Type Description
resourceEventTime DateTime Date and time when the resource was created or updated (for CreatedOrUpdated event), or deleted (for Deleted event).

To better assist you with specific feedback about a certain event, provide the following information:

For missing events:

  • System topic type name
  • Approximate timestamp in UTC when the operation was executed

For event that was delayed or has unexpected content

  • System topic type name
  • Entire contents of the notification excluding data.resourceInfo.properties
  • Description of issue encountered and impacted field values

Ensure that you aren't providing any end user identifiable information while you're sharing this data.
