How to check whether my user data passing to EC2 instance is working | AWS EC2 bootstrap script log

The cloud-init output log file (/var/log/cloud-init-output.log) captures console output so it is easy to debug your scripts following a launch if the instance does not behave the way you intended.

This will give the output of bootstrap execution
