How can I send HorizontalPodAutoscaler metrics to AWS CloudWatch?

Question

I've just set up the AWS CloudWatch agent in my Kubernetes cluster to collect cluster metrics and forward them to CloudWatch. I followed this AWS documentation.

I can't see any metrics from HorizontalPodAutoscaler. I would like to have a graph that shows the number of running / desired pods, and the CPU utilization calculation that it uses to determine the autoscaling behavior.

Can I configure something in cwagent-configmap.yaml or cwagent-daemonset.yaml so that the CloudWatch agent is also sending information about HorizontalPodAutoscaler events and metrics? (Or can I already see this information somewhere in CloudWatch?)

cwagent-configmap.yaml:

# create configmap for cwagent config
apiVersion: v1
data:
  # Configuration is in Json format. No matter what configure change you make,
  # please keep the Json blob valid.
  cwagentconfig.json: |
    {
      "logs": {
        "metrics_collected": {
          "kubernetes": {
            "metrics_collection_interval": 60
          }
        },
        "force_flush_interval": 5
      },
      "metrics": {
        "metrics_collected": {
          "statsd": {
            "service_address": ":8125"
          }
        }
      }
    }
