How to Measure
Throughput
Use the
ReadBytes
and
WriteBytes
metrics with the
Sum
CloudWatch
statistic. For example, the
Sum
value of the
ReadBytes
metric over a sample
period of 5 minutes divided by 300 seconds gives you the throughput as a rate
in bytes per second.
Latency
Use the
ReadTime
and
WriteTime
metrics with the
Average
CloudWatch
statistic. For example, the
Average
value of the
ReadTime
metric gives you
the latency per operation over the sample period of time.
IOPS
Use the
ReadBytes
and
WriteBytes
metrics with the
Samples
CloudWatch
statistic. For example, the
Samples
value of the
ReadBytes
metric over a
sample period of 5 minutes divided by 300 seconds gives you IOPS.
Throughput to AWS
Use the
CloudBytesDownloaded
and
CloudBytesUploaded
metrics
with the
Sum
CloudWatch statistic. For example, the
Sum
value of the
CloudBytesDownloaded
metric over a sample period of 5 minutes divided
by 300 seconds gives you the throughput from AWS to the gateway as bytes
per second.
Latency of data to
AWS
Use the
CloudDownloadLatency
metric with the
Average
statistic. For
example, the
Average
statistic of the
CloudDownloadLatency
metric gives
you the latency per operation.
To measure the upload data throughput 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
CloudBytesUploaded
metric.
5. For
Time Range
, choose a value.
6. Choose the
Sum
statistic.
7. For
Period
, choose a value of 5 minutes or greater.
8. In the resulting time-ordered set of data points, divide each data point by the period (in seconds) to
get the throughput at that sample period.
The following image shows the
CloudBytesUploaded
metric for a gateway volume with the
Sum
statistic. In the image, the cursor over a data point displays information about the data point, including
its value and bytes uploaded. Divide this value by the
Period
value (5 minutes) to get the throughput at
that sample point. For the point highlighted, the throughput from the gateway to AWS is 555,544,576
bytes divided by 300 seconds, which is 1.7 megabytes per second.
