Creating a VPC Flow Log
Function
This API is used to create a VPC flow log.
A VPC flow log captures information about the traffic going to and from your VPC. You can use flow logs to monitor network traffic, analyze network attacks, and to determine whether security group and network ACL rules need to be modified.
VPC flow logs must be used together with the Log Tank Service (LTS). You need to create a log group and a log topic in LTS, and then create a VPC flow log.

The VPC flow log function is now available in CN North-Beijing4, CN East-Shanghai1, CN South-Guangzhou, CN Southwest-Guiyang1, CN-Hong Kong, AP-Bangkok, AP-Singapore, LA-Mexico City2, and AF-Johannesburg.
