Please guide me with the name of WHM Cpanel in which CPU usage and current running process will display same like Hostgator's panels have.?
Version 11.30 or later will display this information in the sidebar of cPanel&WHM if you are running CloudLinux. CloudLinux is required to have this functionality in cPanel&WHM.
EDIT: You will need to be using the X3 theme (any style/branding of the X3 theme will work) to view this information.
Furthermore, keep in mind that HostGator substantially customizes our software so they do have some items in their display that we do not, for example: inode usage.
