Cloudwatch agent installation: Make sure to attach a cloudwatch role to your ec2 instance. amazon-cloudwatch-agent.json file should be created before hand (on your local machine or from where you are executing your ansible playbook), other wise cw_agent will not start. Below is the example of amazon-cloudwatch-agent.json.
