Front-end I/O metrics
The following metrics report cache-level information on system read and write
operations. All these metrics take one dimension (FileCacheId) and are
published into the AWS/FSx namespace in CloudWatch.

Description |
DataReadBytes |
The number of bytes for cache read operations.
The Sum statistic is the total number of bytes associated with
read operations during the period. The Minimum statistic is the
minimum number of bytes associated with read operations on a single disk. The
Maximum statistic is the maximum number of bytes associated with
read operations on the disk. The Average statistic is the average
number of bytes associated with read operations per disk. The
SampleCount statistic is the number of disks.
To calculate the average throughput (bytes per second) for a period, divide
the Sum statistic by the number of seconds in the period.
Units:
Valid statistics: Sum, Minimum,
Maximum, Average, SampleCount.

DataWriteBytes |
The number of bytes for cache write operations.
The Sum statistic is the total number of bytes associated with
write operations. The Minimum statistic is the minimum number of
bytes associated with write operations on a single disk. The Maximum
statistic is the maximum number of bytes associated with write operations on the
disk. The Average statistic is the average number of bytes associated
with write operations per disk. The SampleCount statistic is the
number of disks.
To calculate the average throughput (bytes per second) for a period, divide
the Sum statistic by the number of seconds in the period.
Units:
Valid statistics: Sum, Minimum,
Maximum, Average, SampleCount.

DataReadOperations |
The number of read operations.
The Sum statistic is the total number of read operations. The
Minimum statistic is the minimum number of read operations on a
single disk. The Maximum statistic is the maximum number of read
operations on the disk. The Average statistic is the average number
of read operations per disk. The SampleCount statistic is the number
of disks.
To calculate the average number of read operations (operations per second) for
a period, divide the Sum statistic by the number of seconds in the
period.
Units:
Valid statistics: Sum, Minimum,
Maximum, Average, SampleCount.

DataWriteOperations |
The number of write operations.
The Sum statistic is the total number of write operations. The
Minimum statistic is the minimum number of write operations on a
single disk. The Maximum statistic is the maximum number write
operations on the disk. The Average statistic is the average number
of write operations per disk. The SampleCount statistic is the number
of disks.
To calculate the average number of write operations (operations per second)
for a period, divide the Sum statistic by the number of seconds in
the period.
Units:
Valid statistics: Sum, Minimum,
Maximum, Average, SampleCount.
|
MetadataOperations |
The number of metadata operations.
The Sum statistic is the count of metadata operations. The
Minimum statistic is the minimum number of metadata operations per
disk. The Maximum statistic is the maximum number of metadata
operations per disk. The Average statistic is the average number of
metadata operations per disk. The SampleCount statistic is the number
of disks.
To calculate the average number of metadata operations (operations per second)
for a period, divide the Sum statistic by the number of seconds in
the period.
Units:
-
Count for Sum, Minimum, Maximum,
Average, and SampleCount.
Valid statistics: Sum, Minimum,
Maximum, Average, SampleCount.
