AWS Storage Gateway User Guide
Using Amazon CloudWatch Metrics
a better perspective on how your gateway and volumes are performing. For detailed information about
CloudWatch, see the Amazon CloudWatch User Guide.
Using Amazon CloudWatch Metrics
You can get monitoring data for your gateway using either the AWS Management Console or the
CloudWatch API. The console displays a series of graphs based on the raw data from the CloudWatch
API. You can also use the CloudWatch API through one of the Amazon AWS Software Development Kits
(SDKs) or the Amazon CloudWatch API tools. Depending on your needs, you might prefer to use either
the graphs displayed in the console or retrieved from the API.
Regardless of which method you choose to use to work with metrics, you must specify the following
information:
• The metric dimension to work with. A dimension is a name-value pair that helps you to uniquely
identify a metric. The dimensions for Storage Gateway are GatewayId, GatewayName, and VolumeId.
In the CloudWatch console, you can use the Gateway Metrics and Volume Metrics views to easily
select gateway-specific and volume-specific dimensions. For more information about dimensions, see
Dimensions in the Amazon CloudWatch User Guide>.
• The metric name, such as ReadBytes.
The following table summarizes the types of Storage Gateway metric data that you can use.
CloudWatch
Namespace
Dimension Description
GatewayId,
GatewayName
These dimensions filter for metric data that describes
aspects of the gateway. You can identify a gateway to
work with by specifying both the GatewayId and the
GatewayName dimensions.
Throughput and latency data of a gateway are based on all
the volumes in the gateway.
Data is available automatically in 5-minute periods at no

StorageGateway
VolumeId This dimension filters for metric data that is specific to a
volume. Identify a volume to work with by its VolumeId
dimension.
Data is available automatically in 5-minute periods at no
charge.
Working with gateway and volume metrics is similar to working with other service metrics. You can
find a discussion of some of the most common metrics tasks in the CloudWatch documentation listed
following:
• Viewing Available Metrics
• Getting Statistics for a Metric
• Creating CloudWatch Alarms
