The following metrics are provided for FSx for ONTAP second-generation file systems. For the metrics, a datapoint is emitted for each HA pair and for each aggregate (for storage utilization metrics).
Note
If you have a file system with multiple HA pairs, you can also use the single-HA pair file system metrics and the volume metrics.
Network I/O metrics
All of these metrics take two dimensions, FileSystemId
and FileServer.
FileSystemId– Your file system's AWS resource ID.FileServer– The name of a file server (or node) in ONTAP (for example,FsxId01234567890abcdef-01). Odd-numbered file servers are preferred file servers (that is, they service traffic unless the file system has failed over to the secondary file server), while even-numbered file servers are secondary file servers (that is, they serve traffic only when their partner is unavailable). Because of this, secondary file servers typically show less utilization than preferred file servers.

throughput for your file system. This metric is equivalent to the maximum

FileServerDiskThroughputUtilization |
The disk throughput between your file server and aggregate, as a percentage of the
provisioned limit determined by throughput capacity. All traffic is considered in this

FileServerCacheHitRatio |
The percentage of all read requests which are served by data that resides in your file system's RAM or NVMe caches for each of your HA pairs (for example, the active file server in an HA pair). A higher percentage indicates a higher ratio of cached reads to total reads. All I/O is considered, including background tasks (such as SnapMirror, tiering, and backups). There is one metric emitted each minute for each of your file system's file servers. Units: Percent The The The Valid statistics: |
Disk I/O metrics
All of these metrics take two dimensions, FileSystemId
and Aggregate.
FileSystemId– Your file system's AWS resource ID.Aggregate– Your file system's performance tier consists of multiple storage pools called aggregates. There is one aggregate for each HA pair. For example, aggregateaggr1maps to file serverFsxId01234567890abcdef-01(the active file server) and file serverFsxId01234567890abcdef-02(the secondary file server) in an HA pair.

There is one metric emitted each minute for each of your file system's aggregates. The The The The To calculate read disk throughput (bytes per second) for any statistic, divide the statistic by the seconds in the period. Units: Bytes Valid statistics: |

by the number of HA pairs for your file system). This differs from

Detailed file system metrics
Detailed file system metrics are detailed storage-utilization metrics for each of your
storage tiers. Detailed file system metrics have either the FileSystemId,
StorageTier, and DataType dimensions, or the
FileSystemId, StorageTier, DataType, and
Aggregate dimensions.
When the
Aggregatedimension is not supplied, the metrics are for your entire file system. TheStorageUsedandStorageCapacitymetrics have a single data point each minute corresponding to the file system's total consumed storage (per storage tier) and total storage capacity (for the SSD tier). Meanwhile, theStorageCapacityUtilizationmetric emits one metric each minute for each aggregate.When the
Aggregatedimension is supplied, the metrics are for each aggregate.
The meaning of the dimensions are as follows:
FileSystemId– Your file system's AWS resource ID.Aggregate– Your file system's performance tier consists of multiple storage pools called aggregates. There is one aggregate for each HA pair. For example, aggregateaggr1maps to file serverFsxId01234567890abcdef-01(the active file server) and file serverFsxId01234567890abcdef-02(the secondary file server) in an HA pair.StorageTier– Indicates the storage tier that the metric measures, with possible values ofSSDandStandardCapacityPool.DataType– Indicates the type of data that the metric measures, with the possible valueAll.
There is a row for each unique combination of a given metric and dimensional key-value pairs, with a description of what that combination measures.
