Cloudwatch (if enabled for the vpc) has the log including those of vpn for your instance - maybe one means is to create a CloudWatch metric filter first and set an alarm for specific flow log of interested use case. http://docs.aws.amazon.com/AmazonVPC/latest/UserGuide/flow-logs.html#flow-logs-cw-alarm-example

More on Cloudwatch log
You can create alarms that will fire if certain types of traffic are detected; you can also create metrics to help you to identify trends and patterns.

The information captured includes information about allowed and denied traffic (based on security group and network ACL rules). It also includes source and destination IP addresses, ports, the IANA protocol number, packet and byte counts, a time interval during which the flow was observed, and an action (ACCEPT or REJECT).

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 ten minutes after you create the Flow Log.

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

Even Sophos has its dashboard to see the vpc vpn log (see pg7/8) https://www.sophos.com/en-us/medialibrary/PDFs/other/UTM-on-AWS-FAQ.PDF
