Cloudwatch Alarms

[jfpaulin]

🙍 Problem Statement

I'm currently changing the way I'm creating alarms in AWS Cloudwatch. I was using the AWS CLI but now I want to use this cookbook.
The problem I have is that when I was creating alarms using CLI, I could set the value for "Missing data treatment" using this parameter here :
--treat-missing-data breaching
It does not seem to be possible right now using the latest cookbook's version.

❔ Possible Solution

Maybe just adding a new property for the resource and use that property when creating the alarm.

Thanks for your help.

👋 I took a look and I think it might be supported, can you confirm if insufficient_data_actions is what you are looking for?

Thanks for your answer, but no. Using insufficient_data_actions tells CloudWatch what action to take when the alarm falls into Insufficient data state.

--treat-missing-data breaching tells CloudWatch that when there is no data found, the alarm should be put in Alarm state.

Thanks again!

I see; it looks like we would need to add treat_missing_data to the options in the section I linked above, with the possible values of (breaching | notBreaching | ignore | missing), and a default of missing based on your explanation and a quick review of https://docs.aws.amazon.com/sdk-for-ruby/v3/api/Aws/CloudWatch/Client.html. I am happy to review it if someone wants to take a crack at this.
