Cloudwatch : cannot see my host in CWAgent(custom namespace) metric - amazon-ec2

Question

I am trying to push the memory usage of my ec2 instance to cloudwatch. I have the cloudwatch agent running in the ec2 instance. I have the config file on AWS ssm. this is how it looks
{
"agent": {
"metrics_collection_interval": 60,
"run_as_user": "root"
},
"logs": {
"logs_collected": {
"files": {
"collect_list": [
{
"file_path": "/var/log/my-service/*.log",
"log_group_name": "my-service",
"log_stream_name": "{instance_id}"
}
]
}
}
},
"metrics": {
"append_dimensions": {
"AutoScalingGroupName": "${aws:AutoScalingGroupName}",
"ImageId": "${aws:ImageId}",
"InstanceId": "${aws:InstanceId}",
"InstanceType": "${aws:InstanceType}"
},
"metrics_collected": {
"disk": {
"measurement": [
"used_percent"
],
"metrics_collection_interval": 60,
"resources": [
"*"
]
},
"mem": {
"measurement": [
"mem_used_percent"
],
"metrics_collection_interval": 60
},
"statsd": {
"metrics_aggregation_interval": 10,
"metrics_collection_interval": 10,
"service_address": ":8125"
}
}
}
}
I am starting cloudwatch agent with this command
sudo
/opt/aws/amazon-cloudwatch-agent/bin/./amazon-cloudwatch-agent-ctl -a
fetch-config -m ec2 -c ssm:AmazonCloudWatch-linux -s
The logs are being pushed from the locations mentioned in the config, but I do not see the memory metric being pushed. If I understand correctly I should see the ip address of my instance under CWAgent--> host under Metrics. Unfortunately, I do not see this.
I tried checking the cloudwatch agent logs under /opt/aws/amazon-cloudwatch-agent/logs
/amazon-cloudwatch-agent.log
I do not see any logs which says, it pushed or trying to push any metric.
Any help is much appreciated.

I believe that do will you see the instance name not IP address
