sensu_aws_cleaner

Overview

A Sensu handler in Go to clean up sensu entries when an AWS EC2 instance dies and also provides cleaning of Route53 records associated with the instance.

AwsCleaner

AwsCleaner is a handler that processes keepalive requests that have gone critical and checks the AWS account in the default region eu-west-1 or the specified one by command line argument -region to find if the instance matching the private IP does not exist or is in terminated or shutting-down state and removes the instance from sensu using the local sensu-api. It also searches all hosted zones in Route53 to match the private IP and removes the record from them. In case of an A record pointing to multiple IPs it will be updated to not include the IP of the instance that doesn't exist anymore.

Requirements: Sensu instance requires the following IAM profile access:

"Action": [
    "ec2:Describe*",
    "route53:ChangeResourceRecordSets",
    "route53:ListHostedZones",
    "route53:ListResourceRecordSets"
],
