Cloud Enterprise Network:ModifyFlowLogAttribute

更新時間:Aug 14, 2025

Modifies the name, description, and capture window of a flow log.

Operation description

This operation is executed asynchronously. After receiving a request, the system returns a request ID before it finishes modifying the flow log. The task is continued in the backend. You can call DescribeFlowlogs to check whether the task has been completed.

  • If the flow log is in the Modifying state, it is still being modified. In this case, you can query information about the flow log but cannot perform other operations on it.

  • If the flow log is in the Active state, the modification task has been completed.

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.
