Architecture

The Amazon FSx Health Monitor is a serverless application that uses AWS Lambda, Amazon CloudWatch Events, and Amazon SNS to monitor the health of Amazon FSx windows file systems in an AWS account. The application consists of the following components:

  • Amazon CloudWatch Events rule
    This rule is backed by a configurable schedule. Based on the schedule the Lambda function is triggered.

  • AWS Lambda function
    This function is invoked by the CloudWatch Events rule and checks all FSx volumes in the linked AWS account for their status. If the status is not AVAILABLE (see here) it publishes a message to the Amazon SNS topic.

  • Amazon SNS topic
    This topic receives notifications from the Lambda function. Users can subscribe to this topic to receive notifications about the health of the FSx file systems.
