Azure resource group as an Event Grid source

  • מאמר

This article provides the properties and schema for resource group events. For an introduction to event schemas, see Azure Event Grid event schema.

Azure subscriptions and resource groups emit the same event types. The event types are related to resource changes or actions. The primary difference is that resource groups emit events for resources within the resource group, and Azure subscriptions emit events for resources across the subscription.

Resource events are created for PUT, PATCH, POST, and DELETE operations that are sent to management.azure.com. GET operations don't create events. Operations sent to the data plane (like myaccount.blob.core.windows.net) don't create events. The action events provide event data for operations like listing the keys for a resource.

When you subscribe to events for a resource group, your endpoint receives all events for that resource group. The events can include event you want to see, such as updating a virtual machine, but also events that aren't important to you, such as writing a new entry in the deployment history. You can receive all events at your endpoint and write code that processes the events you want to handle. Or, you can set a filter when creating the event subscription.

To programmatically handle events, you can sort events by looking at the operationName value. For example, your event endpoint might only process events for operations that are equal to Microsoft.Compute/virtualMachines/write or Microsoft.Storage/storageAccounts/write.

The event subject is the resource ID of the resource that is the target of the operation. To filter events for a resource, provide that resource ID when creating the event subscription. To filter by a resource type, use a value in following format: /subscriptions/<subscription-id>/resourcegroups/<resource-group>/providers/Microsoft.Compute/virtualMachines

Available event types

Resource groups emit management events from Azure Resource Manager, such as when a VM is created or a storage account is deleted.

Event type Description
Microsoft.Resources.ResourceActionCancel Raised when action on resource is canceled.
Microsoft.Resources.ResourceActionFailure Raised when action on resource fails.
Microsoft.Resources.ResourceActionSuccess Raised when action on resource succeeds.
Microsoft.Resources.ResourceDeleteCancel Raised when delete operation is canceled. This event happens when a template deployment is canceled.
Microsoft.Resources.ResourceDeleteFailure Raised when delete operation fails.
Microsoft.Resources.ResourceDeleteSuccess Raised when delete operation succeeds.
Microsoft.Resources.ResourceWriteCancel Raised when create or update operation is canceled.
Microsoft.Resources.ResourceWriteFailure Raised when create or update operation fails.
Microsoft.Resources.ResourceWriteSuccess Raised when create or update operation succeeds.

Example event

The following example shows the schema for a ResourceWriteSuccess event. The same schema is used for ResourceWriteFailure and ResourceWriteCancel events with different values for eventType.

Event properties

An event has the following top-level data:

time string The time the event is generated based on the provider's UTC time.
id string Unique identifier for the event.
data object Resource group event data.
specversion string CloudEvents schema specification version.

The data object has the following properties:

Property Type Description
authorization object The requested authorization for the operation.
claims object The properties of the claims. For more information, see JWT specification.
correlationId string An operation ID for troubleshooting.
httpRequest object The details of the operation. This object is only included when updating an existing resource or deleting a resource.
resourceProvider string The resource provider for the operation.
resourceUri string The URI of the resource in the operation.
operationName string The operation that was taken.
status string The status of the operation.
subscriptionId string The subscription ID of the resource.
tenantId string The tenant ID of the resource.
