CloudWatch Agent ec2metadata not available

Question

I have 3 EC2 instances which do not have a public IP address and are connected via a VPN to a private network.  I have installed the CloudWatch agent on them.  When I try to start them using the following command:  
  
$ sudo /opt/aws/amazon-cloudwatch-agent/bin/amazon-cloudwatch-agent-ctl -a fetch-config -m ec2 -c file:/opt/aws/amazon-cloudwatch-agent/bin/config.json -s  
  
I receive the following error:  
ec2metadata is not available  
I! detect region from ecs  
Unable to determine aws-region.  
Please check if you can access the metadata service.  For exampe, on linux, run 'wget -q -O - http://169.254.169.254/latest/meta-data/instance-id && echo'  
Fail to fetch the config!  
  
When I try to run the specified wget command I get a 503 Service Unavailable error.  
  
I am at a loss for how to troubleshoot this further.  Is there a way to specify the Region in the config files for the agent?

Answer

Hello,  
  
thank you for sending this message.  
  
it's possible that this might be a metadata issue and not a region issue. I see that you are using VPN, so I suspect this instances needs to get access to ec2 endpoints.
