AWS Storage Gateway - Measuring Performance between Your Gateway and AWS

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.
