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

1. Log in to the management console.
2. Click in the upper left corner and select the desired region and project.
3. Click Service List and choose Networking > Enterprise Router.

   The Enterprise Router homepage is displayed.

4. Search for the target enterprise router by name.

5. Click the enterprise router name and click Flow Logs.

   The flow log list page is displayed.

6. Locate the target flow log and click View Log Record in the Operation column.

   The LTS console is displayed.

7. View details about the flow log.

   Flow log format:

   <version> <project_id> <resource_id> <instance_id> <srcaddr> <dstaddr> <srcport> <dstport> <protocol> <packets> <bytes> <start> <end> <direct>

   Example 1:
