Operation Description

Usage notes

ModifyFlowLogAttribute is an asynchronous operation. After you send a request, a request ID is returned but the operation is still being performed in the system background. You can call the DescribeFlowlogs operation to query the status of a flow log.

If a flow log is in the Modifying state, the flow log is being modified. In this case, you can query the flow log but cannot perform other operations.
If a flow log is in the Active state, the flow log is modified.
