Dimensions for AWS Storage Gateway Metrics
The Amazon CloudWatch namespace for the AWS Storage Gateway service is
AWS/StorageGateway
.
Data is available automatically in 5-minute periods at no charge.
Dimension
Description
GatewayId
,
GatewayName
These dimensions filter the data you request to gateway-specific
metrics. You can identify a gateway to work by its
GatewayId
or
its
GatewayName
. However, note that if the name of your gateway
was changed for the time range that you are interested in viewing
metrics, then you should use the
GatewayId
.
Throughput and latency data of a gateway is based on all the
volumes for the gateway. For information about working with
gateway metrics, see
Measuring Performance Between Your
.
VolumeId
This dimension filters the data you request to volume-specific
metrics. Identify a storage volume to work with by its
VolumeId
.
For information about working with volume metrics, see
Performance Between Your Application and Gateway
Monitoring the Upload Buffer
You can find information following about how to monitor a gateway's upload buffer and how to create
an alarm so that you get a notification when the buffer exceeds a specified threshold. By using this
approach, you can proactively add buffer storage to a gateway before it fills completely and your storage
application stops backing up to AWS.
You monitor the upload buffer in the same way in both the cached volume and tape gateway
architectures. For more information, see
How AWS Storage Gateway Works (Architecture) (p. 2)
.
Note
The
WorkingStoragePercentUsed
,
WorkingStorageUsed
, and
WorkingStorageFree
metrics represent the upload buffer for the stored volumes setup only before the release of the
cached-volume feature in Storage Gateway. Now you should use the equivalent upload buffer
metrics
UploadBufferPercentUsed
,
UploadBufferUsed
, and
UploadBufferFree
. These
metrics apply to both gateway architectures.

How to Measure
Upload buffer usage
Use the
UploadBufferPercentUsed
,
UploadBufferUsed
, and
UploadBufferFree
metrics with the
Average
statistic. For example, use the
UploadBufferUsed
with the
Average
statistic to analyze the storage usage
over a time period.
To measure upload buffer percent used
1. Open the CloudWatch console at
https://console.amazonaws.cn/cloudwatch/
2. Choose the
StorageGateway: Gateway Metrics
dimension, and find the gateway that you want to
work with.
