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.
