AWS Step Functions is a managed service that lets you build and run serverless workflows by coordinating multiple AWS services. It ensures reliable execution of business processes with visual workflow design and monitoring.
Applications Manager tracks execution outcomes (failed, timed-out, throttled, aborted, succeeded), execution rates, and duration to ensure workflow health. For express state machines, it also monitors billed duration and billed memory to aid cost optimization.
To learn how to create a new AWS Step Function monitor, refer here.
Go to the Monitors Category View by clicking the Monitors tab. Click on the Step Function instance available under Amazon in the Cloud Apps section. Displayed below is the AWS Step Function bulk configuration view distributed into three tabs:
By clicking a monitor from the list, you'll be taken to the AWS Step Function dashboard which includes the following tabs:
