In this step, you visualize the metrics related to your Amazon FSx for Lustre file system using CloudWatch. You can graph several metrics such as the throughput and IOPs. You can also create alarms or display more evolved metrics.
This example looks at the IOPS and free space on the file system as shown in the image below.
To produce a similar graph, follow these steps:
If you want, you can add this graph to a dashboard or build additional metrics as discussed here. In addition, you can set alarms to send notifications on events, such as low storage capacity or high bandwidth utilization. Those notifications can be used to trigger a Lambda function to create and attach a larger file system to your EC2 instances using CloudWatch Events or to send you an email with information about your environment status.
