Viewing Details About a Flow Log¶
Scenarios¶
This section describes how to view details about a flow log, including the attachment ID, source/destination address, source/destination port, data packet size, and packet quantity.
Constraints¶
Flow logs are generated every 10 minutes. After creating a VPC flow log, you need to wait about 10 minutes before you can view the flow log record.
Procedure¶
Log in to the management console.
Click
in the upper left corner and select the desired region and project.Click Service List and choose Networking > Enterprise Router.
