AWS Storage Gateway User Guide
Understanding Gateway Metrics
Monitoring Your Gateway and
Resources
In this section, you can find information about how to monitor a gateway, including monitoring resources
associated with the gateway and monitoring the upload buffer and cache storage. 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.

AWS Storage Gateway provides Amazon CloudWatch metrics at no additional charge. Storage Gateway
metrics are recorded for a period of two weeks. By using these metrics, you can access historical
information and get a better perspective on how your gateway and volumes are performing. For detailed
information about CloudWatch, see the
Understanding Gateway Metrics
For the discussion in this topic, we define
gateway
metrics as metrics that are scoped to the gateway
—that is, they measure something about the gateway. Because a gateway contains one or more
volumes, a gateway-specific metric is representative of all volumes on the gateway. For example, the
CloudBytesUploaded
metric is the total number of bytes that the gateway sent to the cloud during
the reporting period. This metric includes the activity of all the volumes on the gateway.
When working with gateway metric data, you specify the unique identification of the gateway that you
are interested in viewing metrics for. To do this, you specify both the
GatewayId
and the
GatewayName
values. When you want to work with metric for a gateway, you specify the gateway
dimension
in the
metrics namespace, which distinguishes a gateway-specific metric from a volume-specific metric. For
