AWS IoT Things Graph now provides workflow monitoring with AWS CloudWatch

You can now monitor your AWS IoT Things Graph workflows using AWS CloudWatch metrics. You can collect metrics for workflow steps that are executed by AWS IoT Things Graph, including success count, failure count, and total count and then set alarm thresholds for each of these metrics within AWS CloudWatch.  For example, you can set alarms that watch for the number of flows that have failed, and send notifications to a downstream application or to an operator.
