Cloud Attributes

cloud.account.idstringThe cloud account ID the resource is assigned to.111111111111; opentelemetry
cloud.availability_zonestringCloud regions often have multiple, isolated locations known as zones to increase availability. Availability zone represents the zone where the resource is running. [1]us-east-1c
cloud.platformstringThe cloud platform in use. [2]alibaba_cloud_ecs
cloud.providerstringName of the cloud provider.alibaba_cloud
cloud.regionstringThe geographical region the resource is running. [3]us-central1; us-east-1
cloud.resource_idstringCloud provider-specific native identifier of the monitored cloud resource (e.g. an ARN on AWS, a fully qualified resource ID on Azure, a full resource name on GCP) [4]arn:aws:lambda:REGION:ACCOUNT_ID:function:my-function; //; /subscriptions/<SUBSCIPTION_GUID>/resourceGroups/<RG>/providers/Microsoft.Web/sites/<FUNCAPP>/functions/<FUNC>

[1]: Availability zones are called “zones” on Alibaba Cloud and Google Cloud.

[2]: The prefix of the service SHOULD match the one specified in cloud.provider.

[3]: Refer to your provider’s docs to see the available regions, for example Alibaba Cloud regions, AWS regions, Azure regions, Google Cloud regions, or Tencent Cloud regions.

[4]: On some cloud providers, it may not be possible to determine the full ID at startup, so it may be necessary to set cloud.resource_id as a span attribute instead.

The exact value to use for cloud.resource_id depends on the cloud provider. The following well-known definitions MUST be used if you set this attribute and they apply:

  • AWS Lambda: The function ARN. Take care not to use the “invoked ARN” directly but replace any alias suffix with the resolved function version, as the same runtime instance may be invokable with multiple different aliases.
  • GCP: The URI of the resource
  • Azure: The Fully Qualified Resource ID of the invoked function, not the function app, having the form /subscriptions/<SUBSCIPTION_GUID>/resourceGroups/<RG>/providers/Microsoft.Web/sites/<FUNCAPP>/functions/<FUNC>. This means that a span attribute MUST be used, as an Azure function app can host multiple functions that would usually share a TracerProvider.

cloud.platform has the following list of well-known values. If one of them applies, then the respective value MUST be used, otherwise a custom value MAY be used.
