I have created an AWS CloudWatch metric that will filter events based on a warning condition from my Lambda. The condition is going to happen rarely and there is not a way for me to ‘falsely trigger it’ for testing purposes.

I would like to create a CloudWatch Alarm based on the newly created Metric. However, it seems that it is not possible via the AWS console to do this until I have at least 1 data point for the Metric, i.e. at least one Lambda invocation where the rare condition has been met.

I realize I can get around this via e.g. the AWS CLI or CloudFormation, but I am trying to guide other users in how they can set this up via the AWS console alone.

Is there really no way to achieve this?
