File Gateway provides on-premises applications with file-based, cached access to virtually unlimited cloud storage. With this launch, you can configure Amazon CloudWatch Logging to log configuration errors, such as insufficient bucket access privileges, or when applications use the gateway to access files that have transitioned to long-term Amazon S3 storage classes. You can subscribe to these log entries and be notified to correct the errors. Normal operations can be resumed and your file share clients can continue to access their data. You can use the new Amazon CloudWatch metrics to monitor CPU, cache disk, and RAM allocated to your gateway, enabling you to detect performance anomalies, and tune resources before your file share clients are impacted.
