How to use FSx for Windows File Server metrics

There are two primary architectural components of each Amazon FSx file system:

  • The file server that serves data to clients accessing the file system.

  • The storage volumes that host the data in your file system.

FSx for Windows File Server reports metrics in CloudWatch that track the performance and resource utilization for your file system's file server and storage volumes. The following diagram illustrates an Amazon FSx file system with its architectural components, and the performance and resource CloudWatch metrics available for monitoring. The key property shown for a set of metrics is the file system property that determines the capacity for those metrics. Adjusting that property modifies the file system's performance for that set of metrics.

FSx for Windows File Server reports metrics in CloudWatch that monitor network I/O, file server performance, and storage volume performance.

Use the Monitoring & performance panel in the Amazon FSx console to view the FSx for Windows File Server CloudWatch metrics described in the following table.

...determine the file server's CPU utilization percentage? CPU utilization CPUUtilization
...determine the file server's memory utilization percentage? Memory utilization MemoryUtilization
Performance – Storage volumes ...determine the throughput for operations that access storage volumes, as a percentage of the provisioned limit determined by HDD Storage Capacity? Disk throughput utilization (HDD) DiskThroughputUtilization
...determine the percentage of available burst credits for throughput for operations that access HDD storage volumes? Disk throughput burst balance (HDD) DiskThroughputBurstBalance
...determine the IOPS for operations that access storage volumes, as a percentage of the provisioned limit determined by SSD Storage Capacity? Disk IOPS utilization (SSD) DiskIopsUtilization
Note

We recommend that you maintain an average throughput capacity utilization under 50% to ensure that you have enough spare throughput capacity for unexpected spikes in your workload, as well as for any background Windows storage operations (such as storage synchronization, deduplication, or shadow copies).
