Step Functions orchestrates workflows across many AWS services:
| Relationship | Tool |
|---|---|
| Invokes Lambda functions | LambdaTool |
| Sends messages to SQS | SQSTool |
| Publishes to SNS topics | SNSTool |
| Reads/writes DynamoDB tables | DynamoDBTool |
| Starts Glue jobs | GlueTool |
| Starts EMR steps | EMRTool |
| Calls API Gateway endpoints | APIGatewayTool |
| Execution logs in CloudWatch | CloudWatchLogTool |
| IAM roles for execution | IAMTool |
| Deployed via CloudFormation | CloudFormationTool |
Step Functions log groups typically follow:
/aws/vendedlogs/states/<state-machine-name>-Logs
Use CloudWatchLogTool → DescribeLogGroups with logGroupNamePrefix: "/aws/vendedlogs/states/" to find them.
ListStateMachines → DescribeStateMachine to explore definition and configuration.ListExecutions with statusFilter: "FAILED" to find failed runs, then GetExecutionHistory to debug step-by-step.StartExecution requires stateMachineArn and accepts a JSON input string.definition in UpdateStateMachine must be valid Amazon States Language JSON.reverseOrder: true in GetExecutionHistory to see the most recent events first.
