Working with SSM Agent
AWS Systems Manager Agent (SSM Agent) is Amazon software that runs on Amazon Elastic Compute Cloud (Amazon EC2) instances,
edge devices, on-premises servers, and virtual machines (VMs). SSM Agent makes it possible
for Systems Manager to update, manage, and configure these resources. The agent processes requests
from the Systems Manager service in the AWS Cloud, and then runs them as specified in the request.
SSM Agent then sends status and execution information back to the Systems Manager service by using the
Amazon Message Delivery Service (service prefix:
ec2messages).
If you monitor traffic, you will see that your managed nodes communicate with
ec2messages.* endpoints. For more information, see Reference: ec2messages,
ssmmessages, and other API operations. For information about porting
SSM Agent logs to Amazon CloudWatch Logs, see Monitoring AWS Systems Manager.
