Monitoring is an important part of maintaining the reliability, availability, and performance of your Amazon Polly applications. To monitor Amazon Polly API calls, you can use AWS CloudTrail. To monitor the status of your jobs, use Amazon CloudWatch Logs.
Amazon CloudWatch Alarms – Using CloudWatch alarms, you watch a single metric over a time period that you specify. If the metric exceeds a given threshold, a notification is sent to an Amazon Simple Notification Service topic or AWS Auto Scaling policy. CloudWatch alarms don't invoke actions when a metric is in a particular state. Rather the state must have changed and been maintained for a specified number of periods. For more information, see Integrating CloudWatch with Amazon Polly.
CloudTrail logs – CloudTrail provides a record of actions taken by a user, role, or an AWS service in Amazon Polly. Using the information collected by CloudTrail, you can determine the request that was made to Amazon Polly. You can also determine the IP address from which the request was made, who made the request, when it was made, and additional details. For more information, see Logging Amazon Polly API calls with AWS CloudTrail.
