I was able to create a cw alarm based on the duration metric (raise alarm if lambda runs for over a minute) using the GUI. But I was wondering how to do this with cloudformation. So far, I have this -
Resources:
testAlarm:
Type: AWS::CloudWatch::Alarm
Properties:
AlarmName: test-alarm
AlarmDescription: "I'm taking too long!"
ComparisonOperator: GreaterThanThreshold
EvaluationPeriods: 1
DatapointsToAlarm: 1
MetricName: Duration
Namespace: aws/lambda
Period: 60
Statistic: Maximum
Threshold: 0
Dimensions:
- Name: 'FunctionName'
Value: 'hello world'
TreatMissingData: notBreaching
I am not able to link the duration metric of the lambda function. I tried doing that with the dimensions above but it understandably doesn't work. Any help would be strongly appreciated!
Edit - doesn't work as in the alarm doesn't turn on, the threshold is 0, so if the duration>0 which I do with time.sleep
, the alarm should be active. But there is no change and the graph doesn't depict duration in the test runs. It does so for the alarm I created with the web console.

Based on the comments, the issue was that it should be:
Namespace: AWS/Lambda
rather then
Namespace: aws/lambda
