Monitoring your global and core networks with Amazon CloudWatch metrics
You can monitor AWS Global Networks for Transit Gateways using CloudWatch, which collects raw data and processes it into readable, near-real-time metrics. These statistics are kept for 15 months, so that you can access historical information and gain a better perspective on how your web application or service is performing. You can also set alarms that watch for certain thresholds, and send notifications or take actions when those thresholds are met. For more information, see the Amazon CloudWatch User Guide.
You can view CloudWatch metrics in your global network for your registered transited gateways, your associated Site-to-Site VPN connections, and your on-premises resources. You can view metrics per transit gateway and per transit gateway attachment, per global network.
For more information about the supported metrics, see the following topics:
For examples of creating alarms, see Creating Amazon CloudWatch Alarms in the Amazon CloudWatch User Guide.
