Cloud Config:GetResourceConfigurationTimeline

Last Updated:Oct 10, 2025

Queries the configuration history of a specified resource. Cloud Config records every configuration and relationship change for a resource in a configuration history. Recording starts after you enable the Cloud Config service. By default, the history is retained for 10 years.

Operation description

Cloud Config provides a configuration history for each resource that it monitors. The details are as follows:

  • For existing resources, the configuration history starts when you enable the Cloud Config service.

  • For new resources created after you enable the service, the configuration history starts when the resource is created. Cloud Config records configuration changes every 10 minutes. When a configuration changes, a new node appears in the history. This node contains the resource configuration details, change details, and the associated management event.

This topic provides an example of how to query the configuration history for a resource named new-bucket. The resource is a bucket in the cn-hangzhou region. The response shows that the creation time of the resource is 1624961112000 (18:05:12 on June 29, 2021, UTC+8).

RAM authorization

The table below describes the authorization required to call this API. You can define it in a Resource Access Management (RAM) policy. The table's columns are detailed below:

  • Action: The actions can be used in the Action element of RAM permission policy statements to grant permissions to perform the operation.

  • API: The API that you can call to perform the action.

  • Access level: The predefined level of access granted for each API. Valid values: create, list, get, update, and delete.

  • Resource type: The type of the resource that supports authorization to perform the action. It indicates if the action supports resource-level permission. The specified resource must be compatible with the action. Otherwise, the policy will be ineffective.

    • For APIs with resource-level permissions, required resource types are marked with an asterisk (*). Specify the corresponding Alibaba Cloud Resource Name (ARN) in the Resource element of the policy.

    • For APIs without resource-level permissions, it is shown as All Resources. Use an asterisk (*) in the Resource element of the policy.

  • Condition key: The condition keys defined by the service. The key allows for granular control, applying to either actions alone or actions associated with specific resources. In addition to service-specific condition keys, Alibaba Cloud provides a set of common condition keys applicable across all RAM-supported services.

  • Dependent action: The dependent actions required to run the action. To complete the action, the RAM user or the RAM role must have the permissions to perform all dependent actions.

ACS::OSS::Bucket

Region

string

Yes

The region ID.

cn-hangzhou

NextToken

string

No

The pagination token that is used in the next request to retrieve a new page of results. If the response of the current request is truncated, you can use this token to retrieve the next page of results.

string

The tags of the resource.

{\"\"hc\"\":[\"\"value2\"\"]}

AccountId

100931896542****

ResourceEventType

string

The type of the resource change event. Valid values:

  • DISCOVERED: A resource is discovered by Cloud Config.

  • DISCOVERED_REVISED: A resource is discovered by Cloud Config through a periodic reconciliation task.

  • MODIFY: A resource is modified.

  • MODIFY_REVISED: A resource modification is recorded through a periodic reconciliation task.

  • REMOVE: A resource is deleted.

Note
  • To ensure data integrity, Cloud Config periodically reconciles resource data. This process can generate resource discovery events, which occur infrequently.

  • The time of an event generated by a reconciliation task is the time when the task discovers the change. This is later than the actual time of the change.
