About aws-network-monitoring
A skill for installing and configuring Amazon CloudWatch Network Flow Monitor agents on EC2 instances, intended for AWS users monitoring network paths. It covers IAM permissions, installation, activation, verification, and troubleshooting.
Key features
- 01Install through SSM Distributor or CLI
- 02Configure IAM permissions for metric publishing
- 03Activate and verify agent status
- 04Troubleshoot 403, missing metrics, and connectivity
Use cases
- 01Deploy network monitoring agents on EC2
- 02Set least-privilege permissions for metric publishing
- 03Verify that agents publish metrics
- 04Investigate missing network monitoring data
MCP support
With the AWS MCP server, it can run SSM commands, attach IAM policies, and validate agent status; standard AWS CLI access is also supported.
Install
Copy the command and run it in a terminal.

Overview
Domain expertise for installing and configuring Amazon CloudWatch Network Flow Monitor agents on EC2 instances. Covers IAM permission setup, agent installation via SSM Distributor or command-line install, agent activation, verification, and troubleshooting.
Network Flow Monitor agents are lightweight software that publish performance metrics (latency, packet loss) to the Network Flow Monitor backend, enabling monitoring of network path health between workloads.
Works best with the AWS MCP server — enables running SSM commands, attaching IAM policies, and validating agent status directly. All guidance also works with standard AWS CLI access.

Security Considerations
- Least-privilege IAM: Attach only
CloudWatchNetworkFlowMonitorAgentPublishPolicyfor publishing metrics andAmazonSSMManagedInstanceCorefor SSM management. Do not use*FullAccesspolicies. - Private subnets: When the instance is in a private subnet, prefer VPC endpoints for SSM (
com.amazonaws.<region>.ssm,.ssmmessages,.ec2messages) over a NAT gateway to keep traffic on the AWS network. - Credential storage: Never embed AWS credentials on the instance; the publish policy MUST be attached to the instance role, not configured as static keys.
- Audit trail: Ensure CloudTrail is enabled in the account so SSM
SendCommandinvocations and IAMAttachRolePolicyactions performed during agent setup are logged for security investigations. - References: CloudWatch Network Flow Monitor security, IAM best practices
