I’m using ansible’s [ec2\_metric\_alarm](https://docs.ansible.com/ansible/latest/modules/ec2_metric_alarm_module.html) for creating CloudWatch metrics alarms. now, I have some metrics defined which uses [metric math](https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/using-metric-math.html), I’m trying to define alarms for those using ec2\_metric\_alarm but I cannot find a way. This [stack overflow question](https://stackoverflow.com/questions/53849899/unable-to-define-math-expression-for-cloudwatch-alarm-in-a-cloudformation-templa) solves the same problem but using CloudFormation template. Let me know if there is a way to do above using ansible’s ec2\_metric\_alarm. Thanks ---

Maybe try using terraform ? I find the terraform module for aws is usually more update than ansible’s aws module Regards Tony
