Check CloudWatch dashboard for resources utilization

[AhmedSa-mir]

We need to monitor our clusters resources (CPU, Mem, etc...) utilization to check how much resources are required for our clusters and whether we should change the instance type or not.
CloudWatch might have dashboards that can help in monitoring resources

[AhmedSa-mir]

EC2 instances CPU utilization is available in CloudWatch default dashboards along with some other few metrics. To get memory utilization and other metrics, we would need to deploy CloudWatch agent daemonset to deploy cloud-watch pod on every node. The agent would gather node metrics and send them to CloudWatch where we can build our custom dashboards. We would be billed per metric per node.
We decided to postpone this a bit until we monitor our current environments setup and costs.
