Monitoring channels using Amazon CloudWatch metrics
You can monitor AWS Elemental MediaLive using Amazon CloudWatch metrics. CloudWatch collects raw data that it receives from MediaLive, and processes it into readable, near real-time metrics that are kept for 15 months. You use CloudWatch to view the metrics. Metrics can help you gain a better perspective about how MediaLive is performing over the short term and long term.
You can 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.
