Differences between AWS CloudWatch alarms created by Console vs. CLI

I Have created simple AWS cloudwatch alarm with console. It is triggered by metric "Cognito-By UserPoolAndUserPoolClient-SignInSuccesses". It works as supposed and sends an email via SNS Topic. I tried to create same alarm with CLI, but it doesn't work. Alarm doesn't get triggered. I compared in console what is difference between those two alarms. When creating alarm with console in metric selection I see metric with information "UserPool" and "UserPoolClient". When using CLI command there isn't parameters to set those two. How could I configure new alarm with CLI so that it is identical to one created in console?

CLI command:

aws cloudwatch put-metric-alarm --alarm-name NewSignupAlarm --alarm-description "New Signup have been done." --alarm-actions arn:aws:sns:eu-west-3:681278469643:NewTestTopic --metric-name SignUpSuccesses --namespace AWS/Cognito --statistic Sum --period 300 --unit Count --evaluation-periods 1 --threshold 0 --comparison-operator GreaterThanThreshold --profile user3 These are missing when created with CLI

Solution

  • These values are dimensions on the metric. You can specify them with the --dimensions parameter, like this:

    --dimensions Name=UserPool,Value=eu-west-3_... Name=UserPoolClient,Value=117...

    Make sure the values are exact, I used ... just to illustrate the usage.
