I am having an issue with CloudWatch Agent on a specific EC2 instance. I have tested on several other instance with no issue. I have attached the defined CloudWatch Agent IAM Role specified here to the instance (test instances as well): https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/create-iam-roles-for-cloudwatch-agent.html
After attaching, I installed to instance (Ubuntu 16, same as test instances), ran wizard, then started the agent. The only modification I made to the .conf is to change the namespace from the default CWAgent.
I am only having issues with this one instance. Here are the log outputs:. As a note, this instance (as well as test instances) do not have awscli installed, and no defined aws credentials stored.
