Issue/Introduction

We have observed that the FSx data in AWS extension is not giving the correct values.

It is showing lower values compared to the actual.

Resolution

Iinvestigatied the discrepancies between AWS CloudWatch metrics and APM (Application Performance Monitoring) data for FSX file systems.

The team analyzed throughput metrics, discovering that APM shows averaged values over 5-minute intervals while CloudWatch displays real-time data, resulting in significantly different values. 

Discussed potential solutions including creating calculated metrics or changing the polling interval to 1 minute specifically for FSX services. Also to be explored are the possibility of implementing max-value alerts to better match threshold settings.
