Monitoring with CloudWatch
You can monitor caches using Amazon CloudWatch, which collects and processes raw data from Amazon File Cache into readable, near real-time metrics. These statistics are retained for a period of 15 months so that you can access historical information and gain a better perspective on how your web application or service is performing. By default, Amazon File Cache metric data is automatically sent to CloudWatch at 1-minute periods. For more information about CloudWatch, see What Is Amazon CloudWatch? in the Amazon CloudWatch User Guide.
CloudWatch metrics are reported as raw Bytes. Bytes are not rounded to either a decimal or binary multiple of the unit.
CloudWatch metrics for an Amazon File Cache resource are organized into three categories:
All CloudWatch metrics for Amazon File Cache are published to the AWS/FSx namespace in
CloudWatch. For each metric, Amazon File Cache emits a data point per disk per minute. To view aggregate
cache details, you can use the Sum statistic. Note that the file servers behind
your caches are spread across multiple disks.
