AWS Certified Solutions Architect - Associate is one of the most sought-after certifications in the IT industry.

Here’s a few tips for those seeking this certification.

Background Knowledge And Experience

AWS recommends “at least one year of hands-on experience designing available, cost-efficient, fault-tolerant, and scalable and distributed systems on AWS.” In other words, if you recently started your career in IT, there are a few things you have to do before you start preparing for this certification.

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.
