How can i notify a result of lambda when status OK(normal) and NG both?

I set a alarm on cloudwatch when status NG. It was working. But when i got OK(normal) status, i couldn't get notify email. I set up custom metrics by lamda result log when OK(normal) status on cloudwatch alarm.

Is it possible on alarm? Is there an any simple way?

It sounds like your requirements are:

  • Trigger an AWS Lambda function when a CloudWatch alarm enters the ALARM state
  • Trigger an AWS Lambda function when a CloudWatch alarm enters the OK state

Each AWS CloudWatch alarm can be configured with multiple Actions.

Therefore, you can create one Action for ALARM and another action for OK:

CloudWatch Alarm notification

The CloudWatch Alarm can send a notification to an Amazon SNS topic. The AWS Lambda function can subscribe to the SNS topic and will be triggered when the alarm sends the notification to SNS.

  • Thank you for a reply. I think the above settings are couldn't notify state from OK to OK. So, i just want to notify when even normal( OK → OK). Is there any way?

    A notification can only be generated when an alarm changes state. There is no facility for sending out continuous notifications of the same status.

  • What do you mean by "monitor a lambda batch is working fine everyday"?

  • It means regardless of lambda(OK, ALARM) result, i wanted to know result. But it seems impossible only on cloudwatch alarm.
