当我们从s3触发lambda函数时。 如何获取lambda被触发的日志。 我想用terraform做这个

Question

Need to get output when trigger lambda function from s3. need to know whether lambda function is triggered or not. I can check in the console but need to be done with the terraform

I tried with resource "aws_cloudwatch_metric_alarm" but no I don't know weather lambda triggered or not

Answer 1

If you don't get an alarm notification then this means that your Lambda executed without any issues. That's the whole point of alarms: To be notified when things go wrong. So you should test your lambda and see if the errors are reported in "Monitoring", check if the alarm is triggered and the notifications sent. In addition you can trigger notifications when your alarm goes from alarm to normal

You could send an SNS notification at the end of your Lambda code, but this approach would be cumbersome, as you would have to figure what' missing.

Setting up your Lambda and the alarms with Terraform is another task You should come up with specific questions about this. What you've tried and what does not work.
