Logging Storage Gateway API Calls with AWS CloudTrail
To measure the data latency from a tape gateway to AWS
1. Open the CloudWatch console at https://console.amazonaws.cn/cloudwatch/.
2. Choose the Metrics tab.
3. Choose the StorageGateway: GatewayMetrics dimension, and find the tape gateway 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 tape gateway's throughput to 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 tape gateway that you want
to work with.
4. Choose the CloudBytesUploaded metric.
5. Define the alarm by defining 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 megabytes for 60 minutes.
6. Configure the actions to take for the alarm state. For example, you can have an email notification
sent to you.
7. 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 tape 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.
6. Configure the actions to take for the alarm state. For example, you can have an email notification
sent to you.
7. Choose Create Alarm.
