How to Create Alarm Mute Rules in AWS CloudWatch Programmatically?

Asked by TechSavvy42
I'm looking to set up a maintenance mode for the alarms on my work's AWS account. I discovered that AWS recently released alarm mute rules, which are exactly what I need. While it works fine through the console, I'm interested in writing a function that can create mute rules for all alarms containing a specific string, as part of an automated workflow. However, I've found that neither the CLI nor the Python SDK (Boto3) currently support this feature. Does anyone know when these mute rules will be available for the CLI or Boto3?

You might want to look into the Boto3 documentation for the CloudWatch client. Here's a link to the API that could help you out: https://docs.aws.amazon.com/AmazonCloudWatch/latest/APIReference/API_PutAlarmMuteRule.html. This API allows you to create mute rules for specific alarms. The MuteTargets parameter should let you specify which alarms you want to mute.

Actually, I think you're mixing up the mute rules with disabling alarms. Disabling alarm actions won't achieve what you need. Just to clarify, here's the documentation for the mute rules: [Configure alarm mute rules](https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/alarm-mute-rules-configure.html). Make sure to use that resource!
