Install the Ansible role gavika.aws_cloudwatchagent via Galaxy

ansible-galaxy install gavika.aws_cloudwatchagent

Create The Playbook File - cw-play.yml :

---
- hosts: all
  become: true
  vars:
  roles:
    - role: gavika.aws_cloudwatchagent

Prepare the AWS CloudWatch Agent configuration

In your variables file, use aws_cloudwatch_agent_config

agent:
    metrics_collection_interval: 60
    run_as_user: "cwagent"
    metrics:
      namespace: "Gavika"
      append_dimensions:
        InstanceId: "${aws:InstanceId}"
      metrics_collected:
        disk:
          measurement:
            - used_percent
          metrics_collection_interval: 60
          resources:
            - "*"
        mem:
          measurement:
            - mem_used_percent
          metrics_collection_interval: 60

In this example, I am using the namespace, Gavika. Feel free to change it. We collect the cpu, disk, diskio, mem and swap metrics. The agent will send these metrics once in 360 seconds.
