@karurung
Is there a specific reason why you add this?

[karurung]

This change is not really necessary, but I think this change will help displaying error codes, makes troubleshooting easier for developers and users, if I understand this code correctly.

[karurung]

Also, the file name is RestartManagement, so I believe my code is helpful to show error types.

Hi, Why is this file using stdout instead of the actual logging infrastructure we have in place?
What actual errors will this change help in debugging? Are there some specific utilities you are looking into debugging?

[karurung]

Hi, I'm new for this project, the reason why I used stdout because it quickly display error codes during development and testing. Especially, I think this helps debugging for RestartManager APIs fails, which making it easier to identify issues.
