AWS FSx File Cache Monitoring
AWS FSx File Cache - Overview
Amazon FSx File Cache is a high-performance caching service used to process file data, regardless of where the data is stored. It provides seamless integration with existing storage environments, providing low-latency access to frequently accessed data without the need for data migration. AWS File Cache monitoring tool offered by Applications Manager helps you to attain effective performance by detecting latency issues and resolving potential bottlenecks.
Note: AWS FSx File Cache monitoring is not supported for AWS China account type.

Monitored Parameters
Go to the Monitors Category View by clicking the Monitors tab. Click on the FSx File Cache instance available under Amazon in the Cloud Apps section. Displayed is the Amazon FSx File Cache bulk configuration view distributed into three tabs:
- Availability tab gives the availability history for the past 24 hours or 30 days.
- Performance tab gives the health status and events for the past 24 hours or 30 days.
- List view tab enables you to perform bulk admin configurations.
By clicking a monitor from the list, you'll be taken to the AWS FSx File Cache dashboard which includes the following tabs:
