AWS Storage Gateway User Guide
Measuring Performance Between Your Gateway and AWS
To measure the data input/output operations per second from an application to a volume
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
Volume metrics
dimension, and find the volume that you want to work with.
4. Choose the
ReadBytes
and
WriteBytes
metrics.
5. For
Time Range
, choose a value.
6. Choose the
Samples
statistic.
7. For
Period
, choose a value of 5 minutes or greater.
8. In the resulting time-ordered sets of data points (one for
ReadBytes
and one for
WriteBytes
),
divide each data point by the period (in seconds) to get IOPS.
The following image shows the
ReadBytes
and
WriteBytes
metrics for a storage volume with the
Samples
statistic. In the image, the cursor over a data point displays information about the data point,
including its value and the number of samples. Divide the samples value by the
Period
value (5 minutes)
to get the operations per second at that sample point. For the point highlighted, the number of write
operations is 24,373 bytes divided by 300 seconds, which is 81 write operations per second.
Measuring Performance Between Your Gateway and
AWS
Data throughput, data latency, and operations per second are three measures that you can use to
understand how your application storage using the Storage Gateway is performing. These three
values can be measured using the Storage Gateway metrics provided for you when you use the correct
aggregation statistic. The following table summarizes the metrics and corresponding statistic to use to
measure the throughput, latency, and input/output operations per second (IOPS) between your gateway
and AWS.
