AWS Storage Gateway User Guide
Measuring Performance Between Your Gateway and AWS
To measure the latency per operation of a gateway
1. Open the CloudWatch console at
https://console.amazonaws.cn/cloudwatch/
2. Choose
Metrics
, then choose the
All metrics
tab and then choose
Storage Gateway
.
3. Choose the
Gateway metrics
dimension, and find the volume that you want to work with.
4. Choose the
ReadTime
and
WriteTime
metrics.
5. For
Time Range
, choose a value.
6. Choose the
Average
statistic.
7. For
Period
, choose a value of 5 minutes to match the default reporting time.
8. In the resulting time-ordered set of points (one for
ReadTime
and one for
WriteTime
), add data
points at the same time sample to get to the total latency in milliseconds.
To measure the data latency from a gateway to AWS
1. Open the CloudWatch console at
https://console.amazonaws.cn/cloudwatch/
2. Choose
Metrics
, then choose the
All metrics
tab and then choose
Storage Gateway
.
3. Choose the
Gateway metrics
dimension, and find the volume that you want to work with.
4. Choose the
CloudDownloadLatency
metric.
5. For
Time Range
, choose a value.
6. Choose the
Average
statistic.
7. For
Period
, choose a value of 5 minutes to match the default reporting time.
The resulting time-ordered set of data points contains the latency in milliseconds.
To set an upper threshold alarm for a gateway's throughput to AWS
1. Open the CloudWatch console at
https://console.amazonaws.cn/cloudwatch/
2. Choose
Alarms
.
3. Choose
Create Alarm
to start the Create Alarm Wizard.
4. Choose the
Storage Gateway
dimension, and find the gateway that you want to work with.
5. Choose the
CloudBytesUploaded
metric.
6. To define the alarm, define the alarm state when the
CloudBytesUploaded
metric is greater than
or equal to a specified value for a specified time. For example, you can define an alarm state when
the
CloudBytesUploaded
metric is greater than 10 MB for 60 minutes.
7. Configure the actions to take for the alarm state. For example, you can have an email notification
sent to you.
8. Choose
Create Alarm
.
To set an upper threshold alarm for reading data from AWS
1. Open the CloudWatch console at
https://console.amazonaws.cn/cloudwatch/
2. Choose
Create Alarm
to start the Create Alarm Wizard.
3. Choose the
StorageGateway: Gateway Metrics
dimension, and find the gateway that you want to
work with.
4. Choose the
CloudDownloadLatency
metric.
5. Define the alarm by defining the alarm state when the
CloudDownloadLatency
metric is greater
than or equal to a specified value for a specified time. For example, you can define an alarm state
when the
CloudDownloadLatency
is greater than 60,000 milliseconds for greater than 2 hours.
