Exam AWS Certified SysOps Administrator - Associate topic 1 question 314 discussion

The following are the steps involved in creating an Amazon CloudWatch alarm and configuring it to publish to an Amazon SNS topic: Go to the Amazon CloudWatch console. In the navigation pane, choose Alarms. Choose Create alarm. In the Alarm details section, do the following: For Metric, choose Amazon FSx for Windows File Server. For Namespace, choose FSxWindowsFileServer. For Metric name, choose FreeStorageCapacity. For Statistic, choose Average. For Threshold, enter 100,000,000,000. For Evaluation period, choose 1 minute. For Alarm actions, choose Add action and then choose SNS topic. In the Select an SNS topic dialog box, choose the SNS topic that you created for the SysOps administrator. Choose Create alarm. Once the alarm is created, it will start monitoring the FreeStorageCapacity metric for the Amazon FSx for Windows File Server file system. If the metric falls below the threshold that you specified, the alarm will enter ALARM state and publish a notification to the SNS topic. The SysOps administrator will then receive an email notification that the file system is running low on space.
