Monitoring Your Volume Gateway
Metric
Description
Use this metric with the
Sum
statistic to measure
throughput and with the
Samples
statistic to
measure IOPS.
Units: Bytes
CloudBytesDownloaded
The total number of bytes that the gateway
downloaded from AWS during the reporting
period.
Use this metric with the
Sum
statistic to measure
throughput and with the
Samples
statistic to
measure input/output operations per second
(IOPS).
Units: Bytes
ReadBytes
The total number of bytes read from your on-
premises applications in the reporting period for a
file share.

premises applications in the reporting period.

Monitoring Your Volume Gateway
In this section, you can find information about how to monitor a gateway in a cached volumes or stored
volumes setup, including monitoring the volumes associated with the gateway and monitoring the
upload buffer. You use the AWS Management Console to view metrics for your gateway. For example,
you can view the number of bytes used in read and write operations, the time spent in read and write
operations, and the time taken to retrieve data from the AWS cloud. With metrics, you can track the
health of your gateway and set up alarms to notify you when one or more metrics fall outside a defined
threshold.
