How to determine which DataSync agent is running on which EC2 instance

Question

We have multiple DataSync Agents deployed to multiple  EC2 instances.

Is there an easy way to see which Agent is running on which EC2 instance?

The AWS Management Console  screens for  DataSync don't not appear to show any identifier which links the agent to its EC2 host instance.
The cli command "aws datasync describe-agent --argent-arn xxxx" doesn't seem to reveal the EC2 instance  and the EC2 screens in the management console don't offer any clue.

We can add custom tags to the EC2 instance but is there any other way to see the link?

Thanks.

Hello,

Greetings for the day!

As of now, Datasync Console or the "Describe-Agent" API call does not return EC2 instance ID or the IP associated. It only displays the below information when running describe-agent API call:

aws datasync describe-agent --agent-arn arn:aws:datasync:ap-south-1:xxxxxxxxxxxx:agent/agent-0f90ffa00ae8axyz2 --region ap-south-1

{
    "AgentArn": "arn:aws:datasync:ap-south-1:xxxxxxxxxxxx:agent/agent-0f90ffa00ae8axyz2",
    "Name": "testDatasync",
    "Status": "ONLINE",
    "LastConnectionTime": "1970-01-01T05:30:00+05:30",
    "CreationTime": "2022-02-18T10:52:03.205000+05:30",
    "EndpointType": "PUBLIC"
}

For now, I would suggest you to use custom tags on EC2 instances associated with Datasync agents to identify them based on the tags that you've assigned.

Thank you!!

The best way as of now is to login(ssh) to the datasync ec2 instance, the agent id will be mentioned in it.
