Monitoring and Metrics
Amazon DynamoDB provides several built-in metrics and monitoring tools that help you track the health, performance, and availability of your tables. Metrics such as read and write capacity, request latency, and error rates enable you to analyze your table's performance and identify any bottlenecks or issues that might impact your application's usability. Monitoring tools like Amazon CloudWatch and AWS CloudTrail can help you collect and analyze these metrics, set up alarms or notifications based on specific thresholds, and track API activities for auditing purposes. By monitoring your tables and understanding your application's access patterns, you can make informed decisions about capacity provisioning, scaling, and optimization to maintain optimal performance while minimizing costs.
