Create an alarm for the metric “StatusCheckFailed” in the script using CLI

Question

I am using cloud watch CLI to write a script . As part of this script I need to create an alarm when the status check fails. Steps followed - 1) First I create a launch config for an AMI 2) Then autoscaling group, scale up policy. 3) Now , I need to create a alarm such that when an instance belonging to Ami ( from step 1) fails, then raise an alarm which essentially creates a new instance.

I am having issues with creating an alarm for the same. Help appreciated.

mon-put-metric-alarm TestAlarm --comparisonoperator LessThanToThreshold --evaluation-periods 1 --metric-name StatusCheckFailed --namespace "AWS/EC2" --period 600 --statistic Average --threshold 1 --alarm-actions arn:aws:autoscaling:TestInstance --dimensions "AutoScalingGroupName=TestAutoScalingGroup"

The error received is Status Check failed not recognized.
