After adding an AWS Cloud Provider to my CloudForms environment, I quickly noticed an absurd amount of AWS errors in the EVM log (/var/www/miq/vmdb/log/evm.log).

AWS Config Errors

After working with RedHat support it was determined to be a bug within the new implementation of the AWS config service. You can fix it one of two ways.

1. Implement the AWS Config Service within AWS, instructions AWS Config Instructions.
2. Create an AWS Zone with its own AWS Worker:
   1. Deploy a second appliance and join it to this appliance. Move one appliance to an AWS zone along with the AWS provider, then disable the event monitor roles. Then do the same for VMware so you can enable the event monitor role for that zone.
