On EC2, when updating Cloudwatch agent to a version > 1.247347.3 you get (OTEL support in the CloudWatch Agent)[https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/CloudWatch-Agent-open-telemetry.html]

To setup a default config you just run:

sudo /usr/bin/amazon-cloudwatch-agent-ctl -a fetch-config -o default -s
# to check if the agent is succesfully configured just run:
netstat -an | grep 55681  # OTLP HTTP Receiver
netstat -an | grep 2000  # AWS X-Ray Receiver
