# Semantic Conventions for Google Cloud Pub/Sub
|
|
|
|
**Status**: [Experimental][DocumentStatus]
|
|
|
|
The Semantic Conventions for [Google Cloud Pub/Sub](https://cloud.google.com/pubsub) 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.
|
|
|
|
`messaging.system` MUST be set to `"gcp_pubsub"`.
|
|
|
|
## Span attributes
|
|
|
|
For Google Cloud Pub/Sub, the following additional attributes are defined:
|
|
<!-- semconv messaging.gcp_pubsub(full,tag=tech-specific-gcp-pubsub) -->
|
|
| Attribute | Type | Description | Examples | Requirement Level |
|
|
|---|---|---|---|---|
|
|
| [`messaging.gcp_pubsub.message.ordering_key`](../attributes-registry/messaging.md) | string | The ordering key for a given message. If the attribute is not present, the message does not have an ordering key. | `ordering_key` | Conditionally Required: If the message type has an ordering key set. |
