Alarm for resource created without tag


I need a cloudwatch alarm, to warn if any resource was created without TAG. I couldn't find any service that would make this work or any guidance. Has anyone done this here?

I understand that you want to detect untagged resources.

In your scenario, it's better to use AWS Config instead of CloudWatch alarms.
AWS Config can check the customized compliance status of resources and notify administrators.

In particular, the required-tag managed rules provided by AWS will be useful to you. It is also possible to expand the range of support for various resources by creating your own custom rules.

Either way, AWS Config is for you.

  • Thank you for your help!

    But do you have any solutions or documentation on how this can be done via CloudWatch? To receive email alerts as soon as resources without TAG are created. Psi I didn't find anything like it.

    Thank you again.

  • CloudWatch conditions monitor metrics and logs, but not tags.

    I don't think there is any documentation, but why do you want to use CloudWatch? You should use Config in your use case.
    You should send email alerts from Config using SNS.
