Amazon’s Virtual Private Cloud (VPC) Flow Logs log the IP network traffic of your VPC, allowing you to troubleshoot traffic and security issues. Flow Log data is stored using Amazon CloudWatch Logs. Once you have created a Flow Log, you can view and retrieve its data in CloudWatch Logs. The Sumo Logic App for Amazon VPC Flow Logs leverages this data to provide real-time visibility and analysis of your environment. It consists of predefined searches, and Live and Interactive Dashboards.
