Creating CloudWatch alarms to monitor metrics - FSx for OpenZFS

You can create a CloudWatch alarm that sends an Amazon SNS message when the alarm changes state. An alarm watches a single metric over a time period that you specify and performs one or more actions based on the value of the metric relative to a given threshold over a specified period of time. The action is a notification that's sent to an Amazon SNS topic or Auto Scaling policy.

Alarms invoke actions for sustained state changes only. CloudWatch alarms don't invoke actions because they are in a particular state. The state must change and remain changed for a specified period of time. You can create an alarm on the Amazon FSx console or the CloudWatch console.

The following procedures describe how to create alarms for Amazon FSx using the console, AWS CLI, and API.

Open the Amazon FSx console at https://console.aws.amazon.com/fsx/.
From the navigation pane, choose File systems, and then choose the file system that you want to create the alarm for.
Choose Actions > View details.
On the Summary page, choose Monitoring and performance.
Choose Create CloudWatch alarm. You are redirected to the CloudWatch console.
Choose Select metrics, and choose Next.
In the Metrics section, choose FSX.
Choose File System Metrics, choose the metric that you want to set the alarm for, and then choose Select metric.
In the Conditions section, choose the conditions for the alarm, and choose Next.

Note
Metrics might not be published during file system maintenance. To prevent unnecessary and misleading alarm condition changes and to configure your alarms so that they are resilient to missing data points, see Configuring how CloudWatch alarms treat missing data in the Amazon CloudWatch User Guide.
If you want CloudWatch to send you an email or SNS notification when the alarm state triggers the action, choose Whenever this alarm state is.

For Select an SNS topic, choose an existing SNS topic. If you select Create topic, you can set the name and email addresses for a new email subscription list. This list is saved and appears in the field for future alarms. Choose Next.

Warning
If you use Create topic to create a new Amazon SNS topic, the email addresses must be verified before they receive notifications. Emails are only sent when the alarm enters an alarm state. If this alarm state change happens before the email addresses are verified, they do not receive a notification.
Fill in the Name, Description, and Whenever values for the metric, and choose Next.
On the Preview and create page, review the alarm and choose Create Alarm.
