How to setup an alarm when Lambda function fails in AWS

Hi Guys,

I have my Lambda functions in AWS. But I don't want to check every time, my functions are running or not. 

How can I create an Alarm for that?

Thank You

Hi@akhtar,

To create an Alarm for Lambda function, follow the below given steps.

• Go to your CloudWatch Console:

• Click "Alarms" at the left, and then Create Alarm.

• Click "Lambda Metrics".

• Look for your Lambda name in the listing, and click on the checkbox for the row where the metric name is "Errors". Click "Next".

• Enter a name and description for this alarm.

• Setup the alarm to be triggered whenever "Errors" is above 0, for 1 consecutive period(s).

• Select "Sum" as the Statistic and 5 minutes (or the amount of minutes that's reasonable for your use case) in the "Period" dropdown.

• In the "Notification" box, click the Select a notification list dropdown and select your new SNS endpoint.

• Click "Create Alarm".

Hope this will help.

Thank You
