Logging and monitoring

Create a Metric Alarm and Filter for VPC changes


Real-time monitoring of API calls can be achieved by directing CloudTrail Logs to CloudWatch Logs and establishing corresponding metric filters and alarms. It is possible to have more than 1 VPC within an account, in addition it is also possible to create a peer connection between 2 VPCs enabling network traffic to route between VPCs. Monitoring changes to VPC will help ensure VPC traffic flow is not getting impacted.
