Enabling VPC Flow Logs

In case the VPC Flows are not enabled, you can enable VPC Flow Logs from the AWS Management Console or the AWS Command Line Interface (CLI), or by making calls to the EC2 API. Here’s how you would enable them for a VPC:

This will display the Create Flow Log wizard:

New Flow Logs will appear in the Flow Logs tab of the VPC dashboard.

The Flow Logs are saved into log groups in CloudWatch Logs. The log group will be created approximately 15 minutes after you create a new Flow Log. You can access them via the CloudWatch Logs dashboard.

Each group will contain a separate stream for each Elastic Network Interface (ENI):

Each stream, in turn, contains a series of flow log records:

Go With the Flow
Here are a couple of things to keep in mind when you use VPC Flow Logs.

Flows are collected, processed, and stored in capture windows that are approximately 10 minutes long. The log group will be created and the first flow records will become visible in the console about 15 minutes after you create the Flow Log.

You can create up to two Flow Logs on one resource.

The Flow Logs will not include any of the following traffic:

  1. Traffic to Amazon DNS servers, including queries for private hosted zones.

  2. Windows license activation traffic for licenses provided by Amazon.

  3. Requests for instance metadata.

  4. DHCP requests or responses.
