Installs, configures, and troubleshoots Network Flow Monitor agents on EC2 instances to monitor network path health. Covers agent installation, IAM permissions, monitoring network paths, and troubleshooting agents reporting no metrics, HTTP 403 errors, or connectivity failures.
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.
