Is there a way to terminate beanstalk environment based on the load balancer traffic?. I would like to terminate the environment if there is no request to load balancer/c name for last one week.

Is it possible to create a feature which would allow you to pull values from a resources metadata and apply it to an action? A couple usecases:
  1. aws.distribution - when enabling logging via the set-attributes it would be nice to have the bucket prefix be something like this: Prefix: '{resource.DomainName}' so that all the logs aren't dumped into the same directory and instead it pulls the DomainName value from the resource metadata and puts it as the bucket logging prefix
  1. aws.distribution/aws.lambda and a few others - being that several resource types don't have the resource created date in their metadata, being able to tag the '{resource.LastModifedTime}' as exact creation time would be nice as well, I know the {now} option currently doesn't work for lambda run policies so this would be one solution. We have to have the creation date for enforcement as we do monthly release cycles and our policies apply to all gear created AFTER that monthly release cycle date so we required to verify a resource was created after 'X' date, otherwise we are not allowed to enforce on it at this time.

Hi all,

Guys, as you know a couple weeks ago EC2 key pairs started supporting tags.
Our issue that we had ton of keys for a long time and I got an idea to clean up them, as example:
every 6 hours run CC job to get over all EC2 instances and if EC2 has a key, find this key and update tags for key: LastUsedTime.
Keys, which doesn't have a tag: LastUsedTime or LastUsedTime more than 30 days, should be removed.

Is it possible to write all this steps with CC?

you use a custodian policy to ensure all vpcs have flow logs set to a known cloud watch log group.. and then you use tools/c7n_log_exporter to send the log groups to a centralized kinesis destination, and optionally to archive them to s3
