+# Semantic Conventions for Azure Messaging systems
+
+**Status**: [Experimental][DocumentStatus]
+
+The Semantic Conventions for [Azure Service Bus](https://learn.microsoft.com/azure/service-bus-messaging/service-bus-messaging-overview) and [Azure Event Hubs](https://learn.microsoft.com/azure/event-hubs/event-hubs-about) extend and override the [Messaging Semantic Conventions](README.md) that describe common messaging operations attributes in addition to the Semantic Conventions described on this page.
+
+## Azure Service Bus
+
+`messaging.system` MUST be set to `"servicebus"`.
+
+### Span attributes
+
+The following additional attributes are defined:
+<!-- semconv messaging.servicebus -->
+| Attribute  | Type | Description  | Examples  | Requirement Level |
+|---|---|---|---|---|
+| [`messaging.servicebus.destination.subscription_name`](../attributes-registry/messaging.md) | string | The name of the subscription in the topic messages are received from. | `mySubscription` | Conditionally Required: If messages are received from the subscription. |
+| [`messaging.servicebus.message.delivery_count`](../attributes-registry/messaging.md) | int | Number of deliveries that have been attempted for this message. | `2` | Conditionally Required: [1] |
+| [`messaging.servicebus.message.enqueued_time`](../attributes-registry/messaging.md) | int | The UTC epoch seconds at which the message has been accepted and stored in the entity. | `1701393730` | Recommended |
+
+**[1]:** If delivery count is available and is bigger than 0.
