I am trying to create a data dog monitor that will alert whenever a specific lambda function has not been invoked within 1 hours. This needs to happen at a scheduled basis and if it has not happened I need an alert.
I have tried to create several monitor queries but it is not working.
My metric query looks like
sum:aws.lambda.invocations{resource:my-lambda-function}.as_count()
These are my alert conditions
I then don't invoke the lambda function as necessary within the 1 hour. Then after the 1 hour passes the monitor never alerts. I think it's because it's not getting any data?
How can I get this to work?
