Unused Servers

UnusedServers module is used to automatically discover unused physical or virtual servers (VMware or AWS) in the infrastructure.

Module will deprecate virtual machines but shutting them down and renaming to <original name>-<Year><Month><Day> so another script can delete them in two weeks.

Physical servers will only be displayed so it is easy to re-claim them if need to.

Module can send output to console as well as send HTML email reports for further analysis.
