------------------------------------------

[~leftnoteasy], [~vinodkv]  the Jira is not assigned, anyone is welcome to pick it up and
continue with suggested additional features. If needed I can spend some cycles on rebasing/fixing
the original minimum value patch but I won't have time to do additional enhancements.

> When all AM attempts crash, there is no record of them in JHS. Thus no easy way to get
the logs. This JIRA automates the procedure by utilizing the jhist file in the staging directory.
