Monitoring AWS VPC tunnels

While many Amazon Web Services resources with “state” have CloudWatch sensors available, AWS VPCs and tunnels unfortunately do not.  If you’re ever in need of a solution to monitor and log the status of VPC tunnels back to another data center or office, my gist below will be right up your alley.  

It uses boto to list all VPCs and tunnels in a region, perform a custom test for tunnel availability, perform a custom action in the event of a down tunnel, and log the current state of all VPCs and tunnels to a CSV file for reporting and review.  

Just plug in your AWS credentials and preferred region at the top of the script and set this up in cron.

    thanks for this script, nice and simple. it was great starting point for me. I’ve modified the script to cater for multiple accounts (which is what we have), account details is read from a yaml file. It saves me time in running the script multiple times for each account.
    If you want my modified version, let me know.

      Thanks, Karim! If you’d like to post it to Github as a gist, I’d be happy to update the post with a reference to it and acknowledgement.

        better late then never. I’ve uploaded here.

    Great script but I can figure out where to look in CloudWatch for this metric.

    Do you also have a script to monitor a DiectConnect virtual interface?
